Mariana is a brilliant coder who discovered her skills in high school after joining the STEAM team. After graduating high school, Mariana attended and graduated from MIT, before being hired to work at the tech up-start Speckulate as a software engineer. Mariana has since witnessed first-hand the blatant sexism and racism in her workplace and is fighting for equality. Upon leaving Speckulate, she pursued her objective of creating an app alongside a team of women. When this failed due to Mariana's secrets surrounding her love life, she was removed from the team and left to find a new career. As she searched for the "new Mariana" she accepted a job at the Law Office of Kathleen Gale, where she works alongside Callie.
Mariana was born May 17, 1998, and is the fraternal twin sister of Jesus. She is the biological daughter of Ana Gutierrez and Gabriel Duncroft, although Gabriel was originally unaware of the twins' birth. Ana and Gabe and a consensual relationship when she was 15 and he was 18, which resulted in Ana's parents having him arrested for having sex with a minor despite her objections. Infuriated with her parents, Ana left home and began drinking and doing drugs more heavily, which was around the time she discovered that she was pregnant.
After the twins were born, Ana was still a drug addict and for this reason, Mariana and Jesus grew up in a tumultuous and unstable environment. Mariana vividly remembers a Christmas when she and Jesus were five years old and left alone at home for what felt like days while Ana was away getting drugs. Mariana described the experience as "terrifying", but, Jesus soothed her despite being scared as well. Following this incident, it became apparent that Ana couldn't care for her children due to her addiction. The siblings were placed into the foster care system soon after.
While the time they were in the foster system is unknown, Mariana was likely only in the system a year or so. Mariana lamented to Callie how she remembered frequently moving around as a foster child, and the various girls she had to room with, and sometimes being put in some "messed up" homes.
One day, Mariana and Jesus' foster parents decided that they couldn't deal with the kids anymore and dropped them off at the police station for CPS to handle. At this time, Stef Foster was a police officer and noticed the children. She approached them and learned their names before giving them each a lollipop. Mariana was quiet and didn't speak to Stef, nor did she accept the candy until Jesus handed it to her. After this, Stef and her partner Lena Adams decided to foster the twins. They brought them into their home, where they became foster siblings with Stef's biological son, Brandon. The twins were later adopted by the couple when they were 11. Mariana once said that she didn't feel true love and safety until Stef and Lena took her and Jesus in.
Mariana is very smart and girly and cares about appearances, in the least hers, very much. She's shown to be popular and is always organizing social events. Frequently, Mariana has shown strong leadership among her peers and is very proactive during a variety of situations, even organizing a protest against Mr. Timothy's firing at Anchor Beach. Not unlike the rest of her siblings, Mariana is extremely loyal and protective over her family and friends.
While she is usually kind, she can be naïve when it comes to certain topics. However, she usually learns from her mistakes. Mariana also loves to gossip and speaks Spanish fluently. Despite her confident exterior, underneath it all, she can be very insecure and sometimes caves into peer pressure to be accepted. This is shown multiple times throughout the series. For example, when seeing old friend Garret had a new edgier scene and friends, she pierced her nose herself at home to fit in. When making it onto the dance team, she had overheard fellow dance teammates claiming she only made it because she's Latina. This led her to dye her hair blonde so she could fit in while distancing herself from her Latin heritage. However, she has learned not to give in to how others make her feel and to be herself.
Mariana is a young, beautiful girl with a pale complexion, dark brown eyes. She has medium length deep brown hair which she wears in a variety of styles: curly, straight, or naturally waved. She has a slim, yet toned and athletic figure. Mariana's clothing sense is very girly; she often wears bright colors, such as pinks, yellows, and blues. She is often seen wearing a mixture of floral dresses and skirts with colorful cardigans and heels, and dark jeans and jackets over bright colored shirts.
While working at Speckulate, her fashion sense was forced to change due to the misogyny at the office. She began wearing jeans, simple t-shirts, and her hair pulled back in a ponytail.
When Lena brings the possibility of the twins meeting their birth mom, Ana, Mariana appears uninterested despite having talked about it excitedly for the past six months (according to Lena). Mariana says she is not ready to meet her yet.
Callie catches Mariana stealing pills from Jesus. It is later revealed when Jesus discovers a large amount of cash, that Mariana was selling the pills because Ana needed money. Jesus was angered and reminded her that Ana abandoned them so she could run off with a "dumbass" and screw whoever she wanted. He was holding a picture of them and ripped it in half. Mariana tearfully tells him that Ana has come back to town. Mariana fakes a stomach ache to sneak out and meet Ana, whom she has been chatting with online. They finally meet, but it is not what Mariana was expecting. Ana takes the money and leaves suddenly. Mariana is devastated and goes home.
Lena and Stef is told that Callie has been taking pills from Jesus and selling them for money by one of Mariana's friends. Later, Jesus convinces Mariana to tell them the truth. She asks him to accompany her while she tells them and he agrees. Jesus seeing how scared she was, ends up taking the blame for Mariana. Lena and Stef abashedly apologize to Callie.
Mariana prepares for her Quinceañera and asks Callie to take Kelsey's place in her court. Callie agrees to do so. Mariana also asks Mike to do the traditional father/daughter dance with her because she is a little embarrassed about having two moms.
During the Quinceanera, Mariana finds out about Jesus and Lexi's relationship and is not happy. Mariana tells Jesus she knows about the relationship. Lexi tries to talk to Mariana in the bathroom but gets the cold shoulder. Mariana ends up dancing with Mike instead of with her moms.
Lena and her mom disagree. Lena's mom thinks that Mariana shouldn't have a party. She also says that just became Mariana thinks she is Latina doesn't mean she's Latina. Lexi insists on leaving but Jesus stops her and says it's his birthday too and that he wants at least one dance with her.
They have cake and have a family photo including Callie and Jude. They show a slideshow of Jesus and Mariana. During the slideshow, it shows some pictures of Mariana and Lexi. Mariana smiles at her. Mariana tells Lena and Stef that she is acting selfish, reflecting on what Jesus said earlier. He called her selfish because they raised her and threw her the party and she wouldn't even dance with them. Mariana apologizes to her moms, who disagree and say she is wonderful. In the end, no one saw but she did dance with them.
Mariana is still mad at Jesus and Lexi for dating and doesn't want Lexi around her at all. Lena tries to tell Mariana that Lexi is Jesus's girlfriend and her best friend and that she should accept that. Mariana tells Lena that that's not what a best friend does. The conversation ends with Mariana leaving and saying "If that's love, I don't want it." Later that day, Mariana sees Garret one of her old friends; her moms' friend's an adopted son. They catch up and he invites her to a poetry slam with him.
The next morning, Mariana and Jude were talking about nail polish and she offered to paint his nails. Jude accepted the offer and Mariana began painting Jude's nails a bright blue. Callie walked in and told Jude not to wear the nail polish to school, and Mariana tells him that he doesn't have to do everything Callie says. He takes Mariana's advice and wears the nail polish to school.
The next day as Mariana goes to a poetry slam where Garret was performing, she performed her first poem. They read the list of people who will be reading again and she is disappointed when she finds out she is not on the list. The next day Mariana gives herself a nose piercing before the whole family goes to Garret's poetry session.
At breakfast, Mariana rebuffs Jesus' wanting to go to a church camp for the weekend with Lexi, and questions his religious beliefs; "Since when are you religious?" Later, Mariana meets with her birth mother, Ana, instead of seeing Garret like she told Lena. They discuss her Quinceañera and Ana even gives her a gift. Back at home, Callie and Mariana discuss Wyatt's party, and Mariana suggests that they should go. Callie reluctantly agrees before they tell the moms that they are going to Wyatt's to watch a movie. At the party, Mariana runs into Kelsey who lets slip that Jesus and Lexi had unprotected sex. Mariana, angry and upset, gets drunk and Callie decides it's time to leave. When Mariana and Callie arrive back home, Mariana makes a scene in front of the dinner party and tells Lexi's parents that Jesus and Lexi had sex. Angry, Stef and Lena put Mariana to bed.
Mariana and Jesus are fighting over the fact that Mariana told Lexi's parents that he and Lexi had sex. Stef ends the fight and tells Mariana that she brought it upon herself. Because of what Mariana did, Lexi's parents refuse to let Jesus date their daughter and have decided to send Lexi to a boarding school. Feeling guilty, Mariana helps Lexi hideout from her parents after running away. While helping Lexi, the girls talk and reconnect. After finding out from Jesus that Lexi and her parents are not legal U.S. citizens, Mariana reveals where Lexi is staying.
During dinner, the phone rings and it's for Mariana. When she answers and realizes it's Ana, she tells her she should not be calling her at home. She tells her birth mother that she has no more money to give her and frustrated, hangs up. Suspicious, Jesus asks Mariana about the phone call and Mariana tells him that Ana is asking for more money. The next day, Jesus and Mariana go to visit Ana at her house. Back home, Jesus tells Mariana they should take their birth mom to a women's shelter. Mariana rebuffs and tells him that they can never go back there. Later, Jesus goes back anyway and worried about her brother, Mariana confesses to Stef and Lena where he might be.
Lena and Mariana pick up Jesus after he lied about his whereabouts. After picking him up, Lena receives a phone call from Mike about Stef's shooting. They immediately drive to the assigned hospital. Meanwhile, Brandon, scared and angry, yells at the twins for their actions. But Callie calms him to which he leaves. Mariana along with Brandon, Jesus, and Lena visit Stef pre-surgery. Mariana (as a child) appears in a flashback of how Stef met the twins. They were dropped off to Stef's precinct after their foster parent said that they couldn't take care of them anymore. Stef, feeling bad, visits the twins giving each a lollipop and they introduce themselves. Back to the current time, Mariana (as a teenager) is going through boxes. Jesus joins her. They notice a poem that the moms have written to them about introducing the twins in their lives. Mariana becomes upset about it, and she asks Jesus "What if they don't us anymore?" Brandon joins the twins. He apologizes for bursting as they are family. The next morning, the rest of the family go back to the hospital. Mariana, feeling like nobody wanted her around, was sitting outside until Lena sat beside her. She explains that her actions were to grow up, and she didn't want supervised visits. Lena comforts her saying "DNA doesn't make a family. Love does." Lena and Mariana embrace.
Mariana tells Callie that she wants Liam put away for his crimes. After class, Lexi reveals to Mariana that it's definite that she'll move to Honduras. Mariana promises to Lexi that she won't tell Jesus, but she ends up telling him anyway. Mariana removes her nose piercing for her moms to please them. Mariana dances with her family. She is asleep when Callie runs away.
Mariana and Jesus get into an argument about who gets to spend time with Lexi before she leaves for Honduras. Jesus enters Mariana's room while she and Lexi are working on their English assignment. He asks for time alone with his girlfriend, but Lexi lets him go after feeling she is letting her best friend down. She tells her that it is complicated when you are in love and that she will understand once she has a boyfriend. Mariana is left angered by this. Jude rushes into Callie and Mariana's bedroom checking her closet and her drawers only to find out that it's empty. The family has a family meeting discussing Callie. Brandon asks Mariana if she thinks Callie is back with Wyatt. She says that she doesn't think as she thinks they broke up a month ago. Brandon doesn't understand why Callie would take off. Mariana says that finally felt like she had a sister. They realize they are late for school until Stef's car won't start. At school, Mr. Timothy tells Mariana that she will need a new partner. She now finds out that Lexi is leaving for Honduras and not returning.
Marianna and Jesus confront Brandon about kissing Callie. Marianna says he is going to tear the family apart. She leaves, and Jesus tells Brandon that he agrees with Marianna. Marianna is recruited by a cute senior named Chase to audition for the school play. Marianna shows up to audition for the school play. She is greeted by Zac, who is a designer for the play. He is unimpressed with Chase, unlike Marianna. He pairs Marianna and Kelsey together to work on costumes. Marianna and Kelsey argue over working with each other. Marianna and Kelsey shop for costumes for the play, but Marianna is nervous that Kelsey will shoplift. While Marianna is trying on a dress, Kelsey shares that she thinks Chase is “hot.” When the girls leave the store, they are stopped by a security guard who wants to check their bags. Kelsey looks nervous. Marianna confronts Kelsey about the hat when Chase appears and spots the hat. He is impressed and says it defines his character. He thanks Marianna for the hat and walks off. Kelsey smiles and tells Marianna she can thank her later.
Mariana takes a liking to Chase and agrees to help him run lines after school. This angers Kelsey, so Mariana decides that neither of them should be with Chase if it means ruining their friendship. She cancels reading lines with him, but to her surprise, Kelsey offers to read lines with him instead. When Kelsey gets detention, Mariana goes to read lines with Chase, and they end up kissing. Kelsey sees this and out of anger, she tells the principal that Mariana was the one who was selling her drugs, getting Mariana suspended.
Mariana is seen getting along with the girls for the United Girls home.
Mariana finally thought she was going to get a sister and then Callie ran away. And top of that her best friend moved thousands of miles away and she lost Jesus as well. Her twin is too focused on juggling his relationship with his girlfriend and a very good friend, Emma. Maybe that’s why Mariana asked Brandon if he was the reason Callie wasn’t staying.
Mariana got caught up in getting the guy of her dreams that all she served to do was make a fool of herself. She also risked her friendship with Zac. He was trying to tell her his true feeling and she ignored him.
Mariana had foolishly ditched her friend, Zac, just to spend time with the boy she had a crush on. Too bad he was a jerk then and is a jerk now. He told everyone at school about her putting her underwear in his pocket. And in his version of events, they hooked up. That’s not the truth but who’s going to believe her. Mariana has to deal with Chase and his friends stuffing his underwear in her locker. Lena and Stef found about it and were forced into talking with her. Panties aren’t the best way to tell a guy you like him. Zac, He was upset with Mariana ditching him but chose to help her get some payback. He wrote a terrible review of Chase’s play and let it go to print. He never liked the way Chase was targeting to her and he’s all too willing to let bygones be bygones between him and Mariana.
Mariana's glad her best friend is back. Although she could do without Lexi’s evidence. Mariana thought she and Zac were just fine being friends. Then Lexi comes along and tells Mariana to open her eyes. If she could see how much Mariana is in love with Zac then why can’t her friend come out and admit it? Lexi had given Mariana the courage to pursue Zac. And once he became clear of the situation he was all for it.

Zac was embarrassed about his mom and this was the reason why he did not call her back that day when they kissed.
In the hallway at school, Marianna sees Zac’s mom who is going to volunteer at the school dance. Zach approaches both of them. When his mom leaves, it is clear Mariana wants Zach to ask her to the dance, He appears to be afraid and opts out of asking her. Callie tells Marianna that she should ask Zac out herself because it appears that he may be a little shy after their previous encounters. We then see Marianna with Zac. She was going to ask him out when he showed her a card that pictured him in a suit. It was his way of asking her to the Winter Ball. Marianna and Zac are dancing when Zac mom cuts in to dance with Zac. She accuses Zac of sleeping with Marianna before running off.

Mariana slips on Jesus's skateboard and breaks her ankle before her dance performance. As a result of Mariana's ankle injury, she and Emma pull an all-nighter so that they can implement coding into their dance performance for the dance-off. When Mariana's dance team performs, Mariana isn't in the dance, but she is replaced by a virtual dancer that she and Emma programmed in. Mariana's dance team combines coding with dance and ends up with a successful dance. After the dance-off, Ana drives Mariana and Jesus home.

Mariana Adams Foster moves to Los Angeles with her adoptive sister, Callie, to pursue their respective job endeavors. When they arrive, they realize the reality of LA differs from the version they created. A string of bad luck follows them as their moving truck is vandalized, their belongings stolen, their new communal living space less-than-perfect, and the guy Mariana moved to The Coterie to pursue takes a liking to Callie. Mariana's job at Speckulate also shows a cause for concern as she witnesses firsthand the sexism running rampid in the workplace.
In Capoeira, Mariana stands in the elevator as she remembers her hookup with Evan. The next morning, she wakes Alice up to ask her to sneak into her room and grab her some clothes. She doesn't want to see Isabella until she has a chance to talk with Raj. At Speckulate, Mariana is conflicted over Raj and Evan, remembering Alice telling her that Isabella’s confession might not be about Raj. Isabella had confessed to Alice that she slept with a past boyfriend but insists she wouldn’t do it again. Alice reminds Mariana to ask herself if Raj would cheat on her. Mariana receives two texts from Raj and Evan asking to talk. The moments after her fling with Evan were awkward as she didn't know what to say to Evan after they had sex. In the present, Mariana's meeting at work isn’t going well and she runs out of it early.
She hides in the bathroom to avoid Raj who texts her to say that he’s no longer confused about Isabella and loves her. She texts Raj back that she loves him and wants to be with him too. She goes to the team office where she sees a message from Isabella confronting Raj about telling Mariana they slept together. She hurries to the Coterie only to find that Isabella has moved out.
That afternoon, Mariana tells Callie that Isabella moved out, though Raj claims he didn’t sleep with her. She tells Callie about sleeping with Evan with Callie understanding her motives. Mariana asks her for advice. Callie suggests working it out unless she doesn’t want to, with Mariana admitting she’s conflicted over things. She asks about Jamie to which Callie admits emotionally that things might be over. Mariana comforts her sister who is emotional.
The next morning, Mariana meets Raj on the roof with him swearing he didn’t sleep with Isabella, which she knows. She thinks their feelings for other people are telling them they shouldn’t be together. She also tells Evan their relationship is complicated with him being her boss, though she thinks things could still work between them. They decide to be in a secret relationship.
That night, Callie arrives at the Coterie and Mariana gives her a letter that came for her, promising that she didn’t open it. Callie gives it back and asks her to open it. The letter tells Callie that she passed the bar and the Coterie residents come out of their hiding spots to celebrate. Callie reveals that Kathleen asked her to quit Legal Aid and work for her, which Callie has accepted. The group toasts with Gael and Callie exchanging a look that Mariana asks about, though Callie claims that nothing happened. Mariana toasts to Callie moving in, and Gael asks about Isabella and why she moved out, to which Mariana lies that Isabella just left and didn’t leave a note. The group decides to have a family dinner.
In Arraignment Day, Callie dresses in her new pantsuit while Mariana encourages her. Mariana hurries into the work elevator and Evan remarks that he is impressed by the work on her activism app and wants to celebrate with the team for the success. They make plans to meet trying to remain discreet in the presence of an employee who is in the elevator. She arrives at the office and her team tells her that something is wrong.
The team tells Mariana that a white supremacist group is spamming Act=ivism and using their app to spread hate. They are also pushing down Malika’s crowdfunding campaign. They decide to delete as much as they can and block the users before Evan finds out, as he might close down the app.
Mariana heads to the sit-in to support Malika, but is kept up-to-date on the white supremacy situation by her team. As soon as she hangs up she is confronted by a group of supremacists who call her racial slurs and intimidate her. Gael appears and records the protestors which continue as they chant for DA Hanson’s re-election and continue to scream “All Lives Matter” to Gael and Mariana. Gael helps Marian retreat into the courtroom. She calls her team who tells her that the activists are using the app to continuously protest and enlist others to help. When they shut down one user five more pop up. The team thinks they should tell Evan, though Mariana disagrees and instructs them to switch to shadow banning which they can fix later. Mariana assures the women in charge that they’re trying to shut-down the users but they’re using the chat feature to intimidate people who might show up. She warns Mariana that even if they shut-down the activists it might be too late to save the app. Patrisse emerges to tell everyone that they have raised the bail money but aren’t going to leave until DA Hanson comes out and they convince her to drop all the charges. Together, they chant “shut it down”.
Mariana enters Evan’s office to see a bucket of roses he was planning to bring her. He asks if that was okay which she says it’s very okay. He asks about the comedy show but she tells him the truth about the app needing to be shut down. He explains they can’t shut down the app as while they created the product they aren’t responsible for what people say. They aren’t political so it isn’t their job to censor anyone. She is worried about bad publicity, but he explains that they are about to release a new media app and can’t shut down act=ivism without guaranteeing bad publicity. They can’t be seen as catering to either side. Mariana doesn’t agree with giving the bigots an online presence but Evan is thinking about business as his hundreds of employees have families they need to provide for. She understands that it’s his choice.
Callie and Mariana return to the Coterie with Callie apologizing for what happened to her app. Callie’s nice suit smells as it’s become her cheap arraignment suit. Mariana wonders if Malika will be okay which Callie hopes for. Gael interrupts to tell them that Malika is back with her charges dropped.
Mariana packs up her desk and convinces her team that ever since they got here they aren’t taken seriously or own their work. She tells Evan that she is leaving the company which he is upset by, especially since she doesn’t know what their future looks like. Mariana walks out of the office and one-by-one, the Byte Club girls agree to leave to create their start-up.
In Whoosh, Pow, Bang, Davia, Gael, and Alice sing happy birthday to Mariana, who sees Callie walking in, looking very confused. Mariana hugs Callie tightly, saying it’s her birthday, though Callie whispers back that it isn’t. Mariana blows out her candles happily.
The Byte Club holds a meeting at The Coterie where they toast to being free from the bro-life at Speckulate. They talk about money and how long they can last without an income, with Mariana estimating three months, while Gina and Claire can last two, but Rachel only three-weeks. They use this as motivation to get funded ASAP. Claire points out that a tech incubator is being held in a few weeks, with Rachel having an idea for an eco-friendly bath and beauty product delivery app. Everyone loves the idea which Rachel calls Bulk Beauty, BB for short, and they toast to not needing Evan anymore. Kelly enters with a bouquet of roses for Mariana.
She remembers having cookies delivered that says DTF and a letter from Evan, saying he is down to fight for her. Callie asks what she plans to do, but Mariana isn’t sure as she can’t tell the team she is dating Evan since they quit in solidarity over him.
In the present, Mariana asks Kelly not to tell her who the roses are from, though Kelly hasn’t had time to read the card. Mariana opens the card which is from Evan, apologizing again by sending the three-dozen roses. She lies to the Byte Club that the roses are from her moms for her birthday. Later that evening, Kelly brings in a huge set of balloons forcing Mariana to lie to Gael and Davia that it’s her birthday since the Byte Club girls are still there.
Alice, Davia, and Gael sing happy birthday to Mariana as Callie walks in. The girls go to their room where Callie is amused by the situation Mariana has managed to get herself in. She also thinks Mariana should tell Evan to stop giving her gifts, though she already talked to Evan. She recalls entering Evan’s apartment which is grand and expensive. He knows the gifts aren’t enough to make up for not shutting down the app, but tells her that he hired a group of moderators to police the hate speech. Speckulate also pulled their promotion for the app with all the profits being donated to the ACLU, which should ensure that the app burns itself out in a few months. She smiles and asks to jump on his trampoline and he joins her in jumping. They proceed to kiss and have sex on the trampoline. At the Coterie, she explains that Evan technically isn’t her boss anymore so she just has to keep her personal and professional lives separate. She plans to tell the fight team girls about her relationship if she and Evan are still dating by the time they get their seed money. A humored Callie reminds Mariana that she can’t celebrate her birthday this year.
Mariana can’t focus on a meeting with her team as she remembers things with Evan after the trampoline, where she told him about the app idea. He doesn’t think it’s a good idea as their coders without experience in retails so they would be in over their heads. He suggests starting with something small to gain capital, like a game app. She’s a little offended by his honesty but he’s confused as she told him not to hold back, which she explains was sarcasm. He doesn't understand sarcasm. He explains that the idea itself is fine but it’s too big of an idea to start with, apologizing for his bluntness. She relays all of this to her team members who agree with her and starting small, creating the next Candy Crush.
In Klompendansen, Callie and Mariana get ready to leave for Jim and Diane’s party, with Callie feeling weird about going after her relationship with Jamie fell apart. At the Coterie, Callie admits that she doesn’t regret what she did and brings up Jerod’s case, which Mariana isn’t sure he knows about. At the house, Mariana convinces Callie to go in but tells her not to tell anyone she’s dating Evan. They ring the bell and Diane answers happily while wearing Dutch wear. Diane explains that in honor of Brandon and Eliza’s Amsterdam adventure, she’s throwing a Dutch-themed party where everyone is dressing up. She tells the surprised sisters to go get changed.
Calle and Mariana emerge and hug everyone as they say hello. Callie whispers in Brandon’s ear that he should have warned them about the outfits, and Brandon whispers back that he didn’t think they wouldn’t come if they knew. The moms ring the bell and Diane leaves to get the door, making a snide comment about them being almost on time. When Diane and Jim are gone, Callie learns that Jim and Diane do know about her and Jamie breaking up but not why they broke up. Mariana whispers to her that them not knowing explains the warm welcome. Brandon also reveals that he didn’t warn their moms about the costumes either.
The Adams Fosters and Hunters go on a tour of the house, and when they emerge, Jamie has arrived. He makes his rounds with hugs, even hugging Mariana who nervously looks to Callie who gives Jamie a brisk nod. The Hunters and Brandon leave for the table while Stef, Lena, Mariana, Callie, and Jude talk about Connor. Mariana slyly asks if they are planning to get back together, but Jude doesn't want to talk about it now. They eventually make their way to the table, with Callie waving Mariana over to their assigned seats together.
Jim asks Jamie how his law firm partners feel about his facial hair, to which Jamie reveals he quit. He didn’t like the track he was on and isn’t sure what he’s doing yet, which upsets Jim. Jim excuses the band so they can talk freely. Eliza chimes in that Jamie might just not know what he wants to do yet, but Jim is convinced that he should have waited to quit until he knew to quit. Mariana adds that she and Callie just quit their jobs which is news to the moms, who thought Callie was still at the clerkship. Callie and Jamie exchange a look from across the table. Mariana tries to cover that she meant Callie’s other job, making Jim question how many jobs she has. Callie explains she left her clerkship early to work at Legal Aid, but now she’s working for a highly regarded defense attorney. Lena asks when this happened. Callie promises she was planning to tell them today. Jim asks Mariana about quitting her job so soon after her app was released, to which Mariana explains it was overrun by white supremacists so she quit. He pointedly asks if he knows any of them. He covers it as a joke but Callie snips back that it isn’t funny. She tells everyone about the verbal attack on Mariana, a revelation that horrifies Stef. Mariana brushes it off as nothing. Diane asks if everyone is ready for their first dish.
The conversation shifts to politics so the children begin to text one another; Mariana asking Callie if she thinks Jamie really quit but she doesn’t know, Carter confronting Jude if he wants Carter to go to UCLA, to which Jude just wants to be sure Carter isn’t coming for him, and Eliza telling Jamie to make their dad stop talking about politics. Jamie asks Eliza if she has a muzzle, Mariana asks if the party can get any more awkward, and Brandon chiming in that it can as he and Brandon have news. The texting continues between everyone, with Eliza asking if Jamie still loves Callie which Mariana points out to Callie that he does. Diane asks everyone to put down their phone so they oblige, though the conversation remains uninteresting to Mariana.
After the meal, Mariana finds her moms hiding in the bathroom as they are "taking a break". Lena asks why she didn’t tell them about the supremacists, but Mariana just didn’t want to upset them. Stef assures her that it’s okay and asks what happens. She explains that the men asked if she was from brown lives matter and told her to go back to Mexico. She tries to claim it’s not a big deal, and Lena comforts Mariana as Stef assures her that she was right to quit. Mariana tries to stand up for Evan just as Callie enters. Lena asks how it is seeing Jamie to which Callie covers that it’s fine. Stef asks why they broke up.
Callie explains why she had and Jamie ended things and the situation behind her reasons for telling the tenants the truth. She asks if what she did was wrong and Mariana chimes in that it isn’t. Lena asks Callie if she thinks it was wrong. Callie isn’t sure which Mariana claims isn’t true. Stef tells Mariana, who she affectionately calls “Miss Thing”, to let her sister speak for herself. Callie thought what she was doing was right but didn't know it would end their relationship. Lena thinks it was the right thing to do with Stef knowing how hard it can be to be in a relationship with someone so different. She tells Callie to decide what she’s willing to compromise, prompting Mariana to remark how she knows about that. Lena asks if things are hard with Raj, and Mariana reveals they broke up, which surprises the moms. Mariana quickly reveals that Brandon and Eliza have news, just as he emerges in the bathroom. He chuckles when everyone says they’re taking a break. He tells about the guest house in the back that he usually hides out in. Stef asks what his news is.
The Adams Fosters emerge from the bathroom as a group and run into Diane. Diane asks why they were all in the bathroom, to which they cover that they were washing their hands. Diane introduces them to Fleur, who will be teaching them traditional dances. Everyone lines up outside as Fleur explains Stef’s role in the dance, which includes an instrument. Their attempts are humorous as the group begins to have fun with the dances, eventually getting the hang of everything. Mariana and Diane gleefully dance together until the song ends.
When the day is over, Callie joins Mariana, her moms, Brandon, Eliza, and the rest of the Hunters at the door where they say goodbye. Stef, Lena, Callie, Mariana, and Corey leave first. Callie is excited to meet Ka’maya, Corey's half-sister that Stef and Lena have decided to foster, while Mariana knew the nest wouldn’t stay empty long. Lena asks Callie if she got the answer she needed when it came to Jamie. Callie feels that she did get an answer - what she did was the only choice she could have made. Lena is proud of the girls for taking such strong stands, and Mariana blurts out that she’s dating Evan. She presses that she isn’t like Callie and can’t ignore her feelings for principals, especially since Evan is doing the best he can which she’s okay with. Stef and Lena are okay with that since she’s being true to herself which is all they can ask. The sisters hug Stef and Lena, then Corey. As they leave, Stef tells them to text when they get home. Stef whispers to Lena that she’s looking forward to dealing with four-year-old problems and kisses her cheek. Corey waves goodbye to the car as Callie and Mariana drive away.
In Because, Men, Mariana teaches Evan her prototype game which he finds satisfying. As he finishes watching the game she goes to get something to eat, with him instantly being agitated by her lack of footwear or socks. He follows her downstairs in his slippers, asking her to consider in-app purchases while she looks for food. As they talk about the perks of in-app purchasing, including the dopamine release it gives, Evan goes behind Marian restoring his fridge to the exact order and straightening the silverware drawer. He abruptly leaves the conversation to get her socks under the guise of not wanting her to catch a cold.
Callie tries to track down a family member of Jerod’s but doesn’t have much luck as his sister won’t answer. Mariana inquires about the phone call so Callie explains the DA’s offer and Kathleen suddenly wants to take the case to trial, putting Jerod in jail for even longer. Mariana asks if that’s legal, which it is, though it is ethically gray. Kathleen thinks that Jerod can’t decide for himself right now, which is why Callie is trying to track down his sister though Kathleen isn’t apprised of the situation. Mariana points out that Callie doesn’t trust Kathleen, though Callie remembers how Marcus told her about Kathleen leaving her old firm under shady circumstances. She worries she made a mistake.
The Byte Club girls meet at the Coterie to discuss in-app purchases, with Claire on board while Rachel and Gina aren’t sure if it’s the right move. Mariana thinks it necessary if they plan to gain investors. The club agrees and makes a note of it, while Rachel asks if they knew that Evan is the co-founder of an app called Day Trader. Evan texts Mariana about dinner reservations while Rachel prattles about how the people involved in Day Trader knew nothing about the stock market but thought it was a big idea, so they pitched it and figured it out after they were funded. Mariana is surprised to hear the information while Rachel and Gina remark that they did it “because, men”. Mariana remembers her conversation in bed with Evan that morning about setting herself up for success and not diving in over her head.
Evan texts Mariana back about her inquiry on dinner being at 11, as he doesn't’ understand if the question mark on the end meant how that idea sounded to him or if she was being sarcastic. She quickly responds that they have to work late on their pitch for tomorrow but the question mark wasn’t sarcastic. He asks if she’s mad at him but then doesn’t send the text as he ponders why she would be mad.
Mariana and the Byte Club girls arrive at the incubator where she gets his text but brushes it off. They are approached by Alex and Sam who heard about their walkout at Speckulate. Sam thinks it’s because of PMS as they’ve “synced cycles” but Mariana brushes it off as they have an idea to pitch. Sam wishes them luck though they already pitched a female app about interior design then proceeds to shower them with sexist remarks. Mariana congratulates them on their work with Alex feigning gratitude then leaves, calling her “Mary-anna” once again. When they leave, Mariana is annoyed by their “figure it out later” mentality when it comes to their app. She vents how men trust other men to figure things out and decide last-minute to pitch Bulk Beauty. The girls are worried as they don’t have a deck, but Mariana thinks it’s time to be bold and figure out the rest later.
Mariana storms into Evan’s apartment as she is mad. She calls him out for being a hypocrite as he told her to start small when he didn’t. He didn’t think they could figure it out because it’s hard, as he meant that it’s stressful as they bit off more than they could chew. They got lucky but they ended up hating each other. She, however, thinks the girl’s only downfall was not believing in their idea which is why they pitched Bulk Beauty. He asks if they bought the app.
Meanwhile, Mariana and the girls leave the meeting defeated as Gina thinks they should have pitched the app idea. Mariana doesn’t want to quit after one pass and convinces them to do it again next time with more preparation.
In Help, Callie and Mariana have trouble sleeping with Rachel’s abrasive snoring. Mariana throws a pillow at her but she sleeps through it. Callie begs Mariana to do something as she has to be up in two hours. Mariana whisper-yells Rachel’s name until the girl jolts awake.
In the morning, Mariana is eating breakfast when Kelly enters wondering who has been using all the hot water. Mariana apologetically reveals that it’s probably her friend Rachel. She remembers a Byte Club meeting where Rachel reveals her cards are maxed out, she doesn’t have next month’s rent, so she’s going to move back with her parents in Indiana. Claire and the women don’t want Rachel to leave as Bulk Beauty was her idea, but Rachel can’t afford to live anywhere. Mariana impulsively recommends living with her. In the present, Mariana claims it’s only for a few nights as Rachel’s place is being tented. Kelly tells Mariana to make sure Rachel takes shorter showers. Malika and Kelly exchange playful banter on their way out of the kitchen. Once alone, Callie asks Mariana how long Rachel is planning to stay since app funding could take a while. She remarks that she’s sorry to be a downer but she needs her sleep. Evan texts Mariana about missing her and having to ditch Rachel, just as Rachel taps her on the shoulder enthusiastically wondering if Mariana is texting a new boy. Mariana lies that it isn’t but Rachel isn’t convinced but leaves anyway, shouting back that they are out of shampoo.
At The Coterie, Mariana and Rachel skype with Claire and Gina about their progress but they haven’t had any luck achieving funding. Gina asks how living together is going, with Rachel quipping that it’s great while Mariana reluctantly agrees. She gets a message from Evan and quickly dismisses it before Rachel can see it. She asks Rachel to join from her computer just as she gets another message from Evan, prompting an excited Rachel to tell the other girls that she thinks Mariana has a new boyfriend. Unable to tell them the truth, Mariana lies that she’s been messaging her brother Jesus who is going through a hard time. The other girls are sympathetic.
That night, Mariana sneaks out of her bedroom and past a snoring Rachel. She changes outfits and hurries out of The Coterie.
Evan and Mariana lay in bed as he asks how long Rachel is staying at The Coterie, but Mariana isn’t sure as they can’t even find an investor. He offers to help but she refuses despite his insistence. She blurts out that she loves him but when he questions it she corrects that she loves him for trying to help, but she also doesn’t want his help. He tells her to think of it as him helping himself since he’s tired of her sneaking out to see him so he’s acting in his self-interest. He wouldn’t be helping her sell it but she politely tells him not, as she wants to do it on her own. Rachel texts Mariana asking where she is.
Mariana meets the Byte Club at a coffee shop with news that they have a meeting. The girls are excited and ask how that is possible. Mariana remembers coming home from her tryst with Evan to an inquiring Rachel, prompting her to lie that she was in the bathroom. Rachel claims she looked everywhere including the other residents but no one found her. Mariana claims she sleepwalks which worries Rachel deeply. Mariana lays down in bed and decides to text Evan to get them a meeting but that’s all. At the shop, Mariana lies about going to an assistant who went to MIT together. Mariana thinks it would be a great team-building exercise for Rachel to stay with the other girls intermittently too.
In New Moon, Mariana and Callie discuss the ceremony since Mariana isn’t thrilled with the idea. Claire texts Mariana to talk about Raj. She remembers collecting Raj’s things to leave in a box on the kitchen table. She opens up to Callie about feeling sad about moving on from Raj, but even though she’s happy with Evan she still loves Raj. Calle understands it’s hard to let go. In the present, Mariana tells Callie about the text from Claire but Callie thinks it can wait. Malika collects everyone’s phones which sparks Mariana to run out with her phone.
Mariana facetimes Claire and she tells Mariana that they have been talking to one another. She wanted to talk to Mariana before anything happened as she doesn’t want things to get here without Mariana’s blessing. Raj arrives for his box so Mariana hangs up to talk with him. She tries to make small talk with him and denies having his NASA shirt, even though she remembers putting it in a drawer after smelling it. He thanks her for the stuff just as she hears animal noises and something bumps the lamp. It falls over and the pair run into the bathroom and hide in the stalls.
Mariana can’t reach any of her Coterie members and panics over what it could be. She talks to animal control about the kind of animal it could and Raj denies it being a bobcat or bigger than one foot. The people promise to be there in a few hours. He goes to leave the stall but she feels safer with him there. She asks if there’s anything new in his life but he declines though he’s looking for a new job. She asks if he’s seeing anyone and he admits that he is but doesn’t want to say the name since she might know his new girlfriend. She then tells him to go back to his stall so he complies. Mariana angrily texts Claire that she knows they’re already dating.
Mariana’s phone rings, and Claire calls and asks if his relationship is serious. He admits that it’s new but not serious. Claire has her ask if it’s exclusive to which he replies no. Mariana hangs up the call while Raj smiles. Gael goes to the bathroom and finds Mariana and Raj. Raj points out that raccoons can carry rabies. When the racoon situation is dealt with, Raj admits to Mariana that he’s missed her and goes to kiss her but she stops him. Raj apologizes to Mariana for misunderstanding the situation. She knows it will always be hard but knows that he and Claire are talking but assures him that Claire is interested in being more than friends. Raj realizes they are over and she pretends to suddenly find the NASA search in her drawer. He thanks her and they hug goodbye.
In Trust, Mariana and the Byte Club pitch Bulk Beauty to Kelly as a practice run, though Gina stumbles on her pitching. In the bathroom, Claire, Rachel, and Mariana agree that Gina’s pitching sucks which is why they asked Kelly, however, Kelly wasn’t listening as she had AirPods in. Gina asks if the group has any feedback for her, so Mariana recommends having more energy.
At the Coterie, Gina’s pitch is louder and exaggerated but still terrible, so Mariana suggests splitting the part for dynamics which all the girls agree with. Gina suggests that she just be in charge of clicking through the slides and is sad when the girls agree.
In the bathroom, Kelly asks Mariana what the deal is with Gina, as she caught her crying in the bathroom the other day. Kelly explains that she did hear the pitch but it wasn’t her place to tell Gina as she isn’t a business partner or friend. Mariana explains that Gina left on her own accord, but Kelly asks if Gina bowed out because Mariana and the girls made her feel like shit. Kelly validates the strategy but tells her to own it.
Mariana and the Byte Club apologize to Gina for cutting down her pitch instead of telling her the truth. Gina notes that they won’t be good partners or friends if they can’t be direct. Gina asks how she can improve, so they give her honest feedback. Gina asks for help on working with that, so Mariana suggests going around and giving honest feedback. Gina tells Claire that it’s difficult for her to abandon past projects but she knows it’s because Claire is just a great problem solver who wants to make it work. Claire tells Rachel that her focus isn’t always great so she misses deadlines, even though the work is elegant in the end. Rachel, in turn, tells Mariana her code is sloppy and the other girls agree.
In Driver's Seat, The Coterie group plays a game that Kelly invented, with nearly everyone being confused. Gael compliments her on the game being specific, with help from Callie. Mariana tells Callie that she got their mom a candle of the month subscription, remembering Callie turning down all her ideas so Mariana lies that there was a pop-up sale.
Kelly, Mariana, and Alice play the game until Kelly becomes angry with the game and leaves. Mariana asks Alice if she’s okay and learns that Alice feels like she sucks at everything, especially Ruby as things are over between them. Alice was tired of being in the passenger seat but now she and Ruby are in different cars. Mariana tells her to figure out what she wants and ask for it. She invites Alice on a date tomorrow night.
Callie is getting ready when Mariana enters and compliments her appearance. Davia wonders why Gael is playing coy but he just doesn’t want to get hurt again nor does he know what she wants. Callie doesn’t think he’s interested anymore and if she’s wrong, as Mariana points out, she’ll keep a different shade in her purse.
Mariana and Alice go to Douro for a date and she puts down Alice’s idea to go there and Alice fails her first test. She tells Alice confidence is sexy.
Mariana and Alice have their date and she tells Alice to take the photos on her phone instead. She tells Alice that it's not okay for someone to change her look, Mariana looks at her phone and then asks if she’s interested in the person or just wants the person to like her. As the night progresses, Mariana tells Alice to learn to say no without lying. Alice finally gives herself confidence which makes Mariana so proud.
Callie is working when Mariana arrives guessing that things didn’t go well with Callie and Gael. Mariana suggests that Gael is playing it cool but Callie isn’t sure, but she has to get work done or Tommy will go to prison. Callie asks about her date with Alice, which Mariana remarks were fun. She remembers telling Alice that if she wants to be in the driver’s seat, she has to stand up for herself and not play games. Alice knows she’s right and remarks on how great Mariana is at this, to which Mariana admits that she isn’t always that way and there is a relationship she feels like the passenger in.
Mariana tells Callie she lied about the candle of the month present being on sale because Callie is always in the driver’s seat and shoots down her ideas. Callie notes that mom wouldn’t have liked any of them, but Mariana is annoyed by this. Their fight escalates to Callie pointing out that Mariana chose LA, The Coterie, their furniture, without consulting. Mariana thinks that lying is the only way she can get what she wants because Callie makes her feel like her opinion isn’t valid. Callie quips back that when Mariana lies she feels like she can’t trust her. Mariana wants them to be a team that compromises, and they promise to try and work on their ideas. Mariana states that the candles are amazing and mom will love them. Callie laughs at this, but when Mariana asks her the time Callie realizes the final piece of their novel defense.
In She's Back, Mariana admits she didn’t think through the situation which Callie thinks is very on-brand for her. Mariana doesn’t think that she should tell the Byte Club girls about her and Evan even if they do sell the pitch, as she doesn’t think they’ll be accepting; they resent, dislike, and distrust him. Callie reminds her that she can’t keep her relationship a secret forever. Mariana asks about the court case and learns that Kathleen is presenting Callie’s novel defense argument in the hopes of getting a continuance. They wish one another luck as Callie leaves.
Mariana and the group pitch Bulk Beauty to investors, where the leader of the board is a woman. They leave the meeting elated as the woman in charge agreed to fund the app. The woman and the CEO Vincent meet the group and he’s excited to talk with them.
Mariana arrives at Evan’s apartment to follow a trail of rose petals and candles that lead outside, where Evan has prepared a twinkle light dinner. He wanted to take her out but knows they can’t be seen together yet. She thanks him for setting up the dinner and the pitch meeting. He just opened the door for her to walk through. He gives her a BB necklace for Bulk Beauty. He got it on Etsy and she likes it and tells him she loves him and he returns the sentiment so they kiss. They wake up in bed in the morning and he asks when she’s going to tell the Byte Club about her. Mariana answers a call from Jackie that sadly tells her that Vincent passed on the project. He usually signs off but didn’t on this one, but assures Mariana it’s a great idea that will land somewhere. Evan apologizes for the app not getting picked up, but Mariana feels responsible as the girls quit their jobs to follow her, but they're out of money now. Evan offers them their jobs back but Mariana and the girls want to put something good in the world and not listen to a boss who didn’t shut down something Evil. She doesn’t feel the same as them but knows that’s what they will say.
Mariana goes to see Vincent and he tells her that Jackie never pitched her idea to him. Jackie appears to ask what’s going on. They talk outside, with Jackie apologizing for lying and even though she loved it she found out about her Speckulate pay gap initiative. The perception is that Mariana and her team are trouble makers, and Jackie doesn’t have the luxury of making a mistake, and Mariana confronting Vincent only validated her concerns.
Mariana tells the group who are mad about the gaslighting and mocking from Speckulate and think Evan is to blame for the toxic work environment. They want to sue Speckulate and Evan Speck for workplace harassment and then use the money to fund Bulk Beauty. Marina refutes the idea and admits that Evan is her boyfriend.
In "Knocked Down", Alice waits for her toast to pop whilst listening to sad music. Malika cries as she walks into the kitchen. Davia is solemn and crying as she gets her breakfast. Mariana sits down with her coffee, also sad. Kelly asks who died and the four sitting girls begin to cry while Kelly worries that Dennis it was Dennis, but the girls protest. None of them want to talk about it. Callie walks in happy and chipper which makes everyone sob.
Mariana and Evan sit in her room to which she admits to telling the girls about their relationship. She told them and they freaked out, angry that she was dating him. Claire jumps to the conclusion that Mariana cheated on Raj with Evan, but Mariana protests the claim. Gina is mad she lied the whole time. Mariana doesn’t think it was a lie as they didn’t have anything to do with them. Rachel asks if the pitch meeting was because of Evan, but Mariana knows it’s because Evan believed in them. She’s sorry that she didn’t tell them but she’s not going to sue him. Claire asserts that they can sue him.
Mariana tells Evan it didn’t go well and about the impending lawsuit because of the harassment and discrimination they experienced. They want to fund Bulk Beauty themselves. Evan is nervous as he fears that it could delay the IPO, as he removed board members to make a deal to control the company. She thinks he should settle but he’s worried about the message it will send. She argues that the complaints aren’t unfounded. Evan retorts that he handled it when he found out. When Act=ivism happened he couldn’t shut it down out of free speech. He offers to be the private silent investor in Bulk Beauty so they’ll get the money instantly.
Mariana visits Evan unannounced as she needs to talk with him.
Callie and Mariana talk on the phone with her knowing that if Mariana does this she might lose Evan, which Mariana knows.
At Evan’s apartment, Mariana reveals that he has to settle with the girl because she told them about the IPO. If he doesn’t want them to go public they have to be paid what they deserve.
Mariana tells Callie that she’s decided to choose her friends instead of Evan. Callie thinks she’s doing the right thing and is proud of her.
Mariana sits with her Byte Club as they thank her for getting the settlement. The tip gave them leverage with the lawyers. Mariana knows it’s the right thing and the least she could do. She asks what their next step is. Rachel reveals that their next steps don’t include Mariana. She asks if this is about Evan.
At Evan’s apartment, he admits he still wants to be with Mariana. She tearfully admits to loving him and wanting him to. But she can’t as she keeps making excuses and that doesn’t make her a better person. She can’t do this anymore. She hugs him as they both cry. She hurries out of the apartment and breaks down in the hall as she cries.
Mariana tells the girls she broke up with Evan asking if they can move on. Claire knows they can’t fix and forget as she betrayed them. They don’t trust her anymore as she only does the right thing when there’s no other option. They don’t need that in the business, their team, or friendships. The girls leave as Mariana sits in the chair crying.
In "Shame", Gael gathers the Coterie group to tell them Isabella is back. He lies that she’s just looking for a job until she can get on her feet. He will stay with Dennis and pay the roommate fees. He asks them to refrain from the usual gossip and treat Isabella nicely. When he’s gone, Kelly remarks that this will be hard for the tea spillers. Mariana asks Callie if she knew already and she does. Davia isn’t okay with it and learns that Dennis already knew. They bicker with Davia abruptly leaving.
Mariana prepares for her job hunt which Callie thinks is exciting. Mariana is mad that the Fight Club Girls kicked her out after she helped them. Callie offers to cover her rent for the month, but Mariana assures her it’s fine. Callie is texting Gael to meet up for lunch, and Mariana offers to make herself scarce that afternoon which Callie appreciates. She’s okay with the situation because he’s a nice guy. Mariana doesn’t trust Isabella and knows that won’t change.
She interviews with a new company, though the pitch mirrors that of Speckulate which gives her flashbacks to the toxic environment she was subjected to. She tells the person she’s interviewing that she’s interested so she’s offered the position. Mariana accepts the position.
Isabella sneaks downstairs to the kitchen where she finds Mariana. She blurts out that she didn’t sleep with Raj, but it doesn’t change anything for Mariana. Isabella apologizes for getting closer than she should have. She understands why Mariana can’t forgive her as she’s the reason they broke up. Mariana remembers Evan and admits that Isabella wasn’t the reason. Isabella presses that she’s trying to be a better person. Mariana appreciates the apology and understands losing friends because she betrayed some too. She apologizes for assuming she was wrong. Mariana offers Isabella liquor and asks about her relationship with Gael. Isabella takes the glass but doesn’t drink it. She brushes it off as not drinking and Mariana realizes that the other part of her being here is a pregnancy.
Meanwhile, Callie is forced to truck through mud and dirt as part of her job assignment for the day. She calls Mariana and asks her to drop off a change of shoes for her at the office. Callie and the group return to the office when Callie finds Mariana answering messages. When Mariana came to the office no one was there and the phone was ringing. She answered it and took messages as they flooded in. When Kathleen entered, Mariana gave her the messages and handed over the messages. Kathleen offers her a job on the spot. Mariana tells Callie about the job.
The sisters talk in the office as Mariana explains that she can’t be her old self anymore. She can’t handle it anymore and knows she’s to blame for the Fight Club and needs to change. But she needs a break from the tech world. She thinks it’ll be fun to work together. Callie introduces Mariana to Tony and Rowan. The boys make more passive-aggressive remarks which make Callie snap. She didn’t ask to be Kathleen’s lawyer and think she was asked because the boys only care about kissing her ass with lattes and scones instead of doing the work. Tony thinks that’s fair enough but tells her not to pretend she doesn’t like being the teacher’s pet or the center of attention. Mariana remarks that Callie does as she was always the center of attention growing up. Callie gives her a pointed look so Mariana stops talking. Kathleen enters with a discovery from the prosecution that says a beer bottle near the drop point has Tommy’s prints on it. They claim it was forgotten from the evidence list. Callie is called aside by Kathleen while Mariana delightfully remarks that this is fun.
That night, Gael calls a Coterie meeting with Isabella present. He tells them that she’s pregnant with his child. She’s going to stay as long as she needs to. The group is quiet for a moment before everyone assures him that they’re supportive of them. Mariana whispers to Callie that she knew about Isabella’s pregnancy, and knew that Callie knew, but didn’t say anything because she’s the new Mariana now. Dennis emotionally shares that he had a son who died at the age of six. He’s kept it to himself because he couldn’t talk about it or handle it. He needs to move through it and everyone here is his family and he can’t hide anymore. They assure him they’ve got him. Kelly apologizes for what she said about his loft. She then stands offering a hug. Malika is touched as she never does that. Dennis chuckles and stands up, hugging Kelly. It isn’t long before it turns into a group Coterie hug. Mariana invites Isabella into the hug.
In "Making a Metamour", Kathleen has a meeting Callie, Tony, and Rowan to prove reasonable doubt. Mariana interrupts since DA Adler is on the line, so Kathleen tells her to take a message. Kathleen refocuses but Mariana interrupts again with another call, so Kathleen tells her to keep taking messages. She invites Mariana into the room to answers the phones. The lawyers are interviewing teenagers who need to reissue their statements to the police since they saw Tommy and Zack fighting at the party.
The trio begins their interviews as they try to dissuade one of the teens from saying that Tommy and Zack were fighting. Mariana tells Callie to ask the kid if he was high that night as she believes the kid is a stoner. When Callie asks the teen if he was intoxicated that night, he claims he didn't smoke or drink. Mariana continues to text Callie her ideas and thoughts as the interviews unfold.
After the interviews, Mariana is sure that Tommy's girlfriend Katie is sketchy, but Tony asks about the fake tears. Mariana begins to swell up and cries fake tears. Callie notes that Mariana is proving a point. Mariana asks if Tommy will go to jail or juvie, with Tony answering that he would go to juvie. Mariana blurts out that Callie can attest to how scary juvie is. Callie tries to make her leave by asking about the phones, but Mariana programmed a boarding system for the calls. Callie gives Mariana a pile of files to file for her. Rowan and Tony ask about Callie being in juvie. Mariana once again says that Callie was in juvie twice and is a badass as she took a baseball bat to her foster father’s car. The men want to nickname her Criminal Callie, but Callie notes there were extenuating circumstances.
Mariana comes home to find Isabella eating ice cream as everything makes her nauseous. Mariana jokes that she’s not craving anchovies which makes Isabella gag. Her morning sickness is all day now. She asks if Callie said anything about this morning and brushes it off when Mariana doesn’t know anything. Isabella wants to do something nice for Gael and Callie but needs Mariana’s help. She happily agrees.
Callie comes into the apartment meets Mariana, who wants to investigate the teenager's social accounts. Callie prefers she uses her skills to act professionally and keep her personal life out of the office. Mariana apologizes but thought they knew since her criminal background is an asset. Callie proclaims she is not a criminal. She also can't see the humor in the situation, as she was worried when they started working together. Mariana was worried Callie would underestimate her. She learns that Kate and Zack aren't following one another on social which Mariana thinks could indicate they aren't friends.
The sisters work together to scroll through the teenager's profiles. Callie thinks she and Mariana are old as they have to pay taxes now. She is incredulous over when she got this old. Mariana notes that they're not old, even if Callie acts old sometimes. They find a comment with a hashtag that Callie's not familiar with, so Mariana finds the hashtag on Katie’s photo too. She searches it and discovers that the account is private. Izzy follows the Instagram account, but not Kate. Mariana thinks it could be Katie’s alternative Instagram account. Mariana suggests asking Izzy about the Instagram account to see what she knows.
Callie and Mariana interview Izzy, but she wasn’t at the party that night. They wanted to ask her about Tommy and Zack’s friendship. Rowan and Tony wonder what the “Sleuthing Sisters are up to. Callie asks Izzy how Katie felt about Zack and Tommy spending so much time together. Mariana asks Callie if she remembers her ex-boyfriend Brad, joking that he was always hanging around with the guys and should have put down the Red Bull and Axe body spray. Izzy laughs and begins to relax.
Callie and Mariana walk up the Coterie steps as Callie frets over being late for work. Mariana notes she has an appointment with the love doctor. Mariana takes Callie to the roof, where Isabella has planned a breakfast for Callie and Gael to spend time together.
The next day, Callie and Mariana tell Kathleen what they learned, but give Tony and Rowan shared credit. Callie notes that after scouring the student’s Instagram. They all discovered that Katie and Zack didn’t follow each other, so they brought in a friend of Katie’s who admitted that Katie was over the relationship.
Izzy admits this to Callie and Mariana, but also that Katie wanted to go to a movie and not the party. But Tommy always did what Zack wanted. Katie wasn’t Zack’s biggest fan but she didn’t hate him. Izzy claims she didn’t talk to Katie since graduation. Mariana asks about the hashtag in the recent photo tagging - #2LDRZAS. Izzy lies that she doesn’t know what it means. She doesn’t get how this helps Tommy and asks to leave.
Callie tells Kathleen that they can get Izzy to follow Mariana on Insta; Mariana created a fake account called @CaturdayNightLive since Izzy loves cats. The boys chuckle and compliment the cleverness of the accounts handle. Mariana is waiting for her to accept her request. She hopes the account has photos from the party. Kathleen tells them they did great work. Tony is curious if they are going to blame Katie. Kathleen notes that they will if she has means and opportunity. Tony thanks the sisters for having his and Tony's backs. Mariana notices that Katie accepted the following request on her Finsta. They find a photo of Katie not being happy on the night of September 3rd, but Katie deletes her Finsta before they can see anything else. Izzie must have tipped her off, so now they don't have anything. Tony asks who’s going to tell Kathleen.
In "Lunar New Year", The Coterie Group gathers for drinks while Gael monitors Isabella’s water intake. She has 48 more ounces to go, which Mariana notes are a lot of water. Kelly notes that their baby will be born in the year of the Ox; they’ll be earnest and honest like this crowd. Callie asks Gael to elaborate on the pregnant women needing more water. He offers a refill which Callie says yes to but he takes Isabella’s instead. Callie then takes Mariana’s drink and downs it.
Callie vents to Mariana about Isabella being capable enough to track her hydration without Gael’s help. She doesn’t get why Gael is acting weird and that he might be rethinking their relationship. Mariana wonders if he worries she’s overwhelmed, but Callie hasn’t said anything about it.
In the bathroom, the other night, Gael asked Mariana about Callie being okay. She states that she doesn’t know for a fact but if it were her, she wouldn’t want to hear every detail about him, Isabella, and the baby.
Mariana admits to Callie that she told Gael to dial back the baby talk. Callie is horrified and asks why she did that.
The other night, Callie talked about Gael and Isabella taking parenting classes. Mariana can’t believe they’re doing it together. Callie thinks it’s the right thing to do even if it is going quickly. Mariana notes that it must be hard and Callie admits that it is, but if Gael told her less it might be easier.
Now, Mariana admits that’s why she told Gael because Callie told her. Callie vehemently states that she told Mariana that not Gael for a reason. Mariana wants her to be honest. She doesn’t know what she wants to know. Callie takes another drink as she needs to unwind and not have Mariana monitor her either. Mariana is later present during all of the Lunar New Year festivities.
Callie calls a group meeting with Isabella, Mariana, and Gael, to talk about their living situation. She has a proposition that will solve everything, though no one realized there was a problem. Callie happily says that Isabella will move in with Mariana, Gael will move back to his loft, and she will move in with him. The trio hesitantly agrees as Callie giggles to drink more.
The next morning, Callie undoes the moving situation. She lays in bed with Mariana to tell her she isn’t moving out and did take her advice to talk with Gael. Mariana thinks it’s good she was honest. She warns that they won’t have a happy ending in every problem in their relationship. Callie wonders when her sister got so wise, to which Mariana retorts this is the new Mariana. The one Callie should have listened to when she told Callie to drink water and not whiskey. Callie admits he was right which thrills Mariana, who makes her say it again. She wants to record it and send it to their moms as video proof. Callie obliges and records the saying. Mariana is thrilled.
In "Opening Statements", Callie and Mariana walk downtown as Mariana complains that there’s nothing for her to do at the office. She wants to be in court but Callie tells her to just supervise the painter. Mariana is a little paranoid about the murder case. They bump into Raj and Claire who are holding hands. Claire says things are going great. However, at Bulk Beauty, Claire and the team are falling apart. They can’t find product partners and focus on writing code. Now, Claire lies that they have more brands signing up than they can handle. Mariana states she’s working at Callie’s law firm doing a lot, even though she lays around most of the time. She stacks office supplies and plays in the copy room. The groups say goodbye with Callie questioning Mariana, who spirals that all she’s capable of is answering phone calls.
Mariana vents to the painter over changing her occupation just as Callie texts her asking her to bring the team coffees. Mariana is enthusiastic about leaving. She stops at the coffee shop and gets the coffees, but notices the names on the cups are those of the Byte Club girls. She turns around and is shocked to see the girls behind her. Flashing backward, Callie got a text from Raj after she and Mariana ran into Raj and Claire. Raj tells Callie that BB is not working without Mariana. Callie admits that Mariana is miserable too. Now, Mariana realizes they’ve been set up.
At The Coterie, Callie comes in to find Mariana eating hazelnut spread out of the jar. Her meeting with the Fight Club goes wrong. Rachel is insistent they’re meeting a coder for an interview. Claire realizes the name is an anagram for Mariana. Raj and Callie must have worked together to pull this off. Mariana wishes them luck on the app and apologizes for all of this. She then leaves. In the present, Callie apologizes as Raj said they needed her. Mariana thinks this was Callie’s way of telling her she didn’t want to work with Mariana either. Callie can see that Mariana is miserable. Mariana knows the girls are done with her and didn’t offer her the job. Callie thinks she should ask for the job, though Mariana doesn’t want to be demoted from partner to employee. Callie thinks it is the only way to prove she’s changed or get friends back. Mariana wants that so Callie tells her to humble herself, as being a coder at BB is better than not being at BB at all.
Mariana visits the fight club girls as she’s there to interview for the new coding job. She gives them her resume. They look at her incredulously as they know she’s overqualified and will be underpaid. She’s okay with that if she gets to work with the right people. She also needs to work on her code per their feedback, so this allows her to do that. Before, the team wanted to hire Mariana as a coder and think she deserves a second chance. Claire is the only skeptical one. Mariana is hired on the spot and starts right away. They don’t let her sit at the table with them as her desk is in the corner. Mariana takes her seat but is visibly hurt by the lack of inclusion.
In "Closing Arguments", Callie gets dressed when Mariana walks in and asks if Isabella is okay since she went to the hospital. Callie remarks that she is but her blood pressure was just elevated so she’s on bed rest. Her date with Gael didn’t really happen which is fine. Mariana asks if that’s really okay since she knows Callie thrives on complications, telling her to look at history. She sought after every complicated situation she could find. She asks how Callie will feel when the baby is born and Gael has even less time. Unless Callie is hopelessly in love she needs to pump the breaks, as she might not even be over Jamie yet. Callie diverts to ask how Mariana’s life with the Fight Club girls are going, calling her Miss Take-The-Easy-Path. Mariana admits it isn’t great but now she has a new interview which will give her an easier path.
Mariana meets with the rival startup and they gush over Zelda. The women have heard about Speckulate and its toxicity towards women. The women then talk about their app and detail the exact same thing that Bulk Beauty is doing. She remembers pitching the app idea during her budget meeting and reflects on the similarities to BB. Mariana lies that it’s original and asks who’s funding it. She learns Jackie Morris from the Hallis group is funding the whole thing. Jackie was the woman who said Vincent passed on the funding. Mariana states that the name sounds familiar.
She rushes back to BB and is scolded for being late as her appointment wasn’t approved by the team. Her code also had some small syntax errors which Claire makes a big deal out of. Mariana snaps back that if it was a mess it’s because she was rushed by Claire, as she can either have things done fast or right. She doesn’t appreciate the way she’s been treated when she’s proven that she’s valuable. Claire tells her to do the work right the first time, prompting Rachel to tell Claire she’s being harsh. Claire retaliates that it was Rachel’s idea to cut Mariana loose, while Rachel argues it was everyone’s decision. Claire doesn’t see the point if they’re just going to let Mariana back in. Mariana argues that she can just lead because she can do more than just code.
Now, Mariana meets with Jackie about Revitalize Beauty and the similarities in concepts. Jackie insists that similarities are purely coincidental. Mariana isn’t there too sure about Jackie but to ask for a job. She pitches herself to Jackie as she’s no longer working with BB. Jackie is worried that Mariana was part of the drama in the group, but Mariana has a glowing recommendation from Evan to prove otherwise. Flashing back to last night, Mariana texted Evan to ask for the recommendation which he happily gave. Now, Mariana tells Jackie that she’s the right person for the job.
Mariana returns to BB and publicly gives her notice that she’s quitting. Flashing back, Mariana tells Claire she wants a chance to prove she can change. Rachel stands up for Mariana as she thinks they should drop their grudge and let Mariana prove she’s changed. Claire relents as it’s exhausting. She agrees as long as there are no more secrets, schemes, or lies. Mariana confesses that she applied for another job. Now, Mariana states she got the job and will burn revitalize beauty to the ground. The girls hug happily. That night, Mariana texts Evan to thank him for the recommendation, but he needs to talk with her. Meanwhile, Evan sits with Jackie admitting that Mariana hasn’t responded yet.
Jesus Adams Foster - (see Jariana) Jesus and Mariana are fraternal twins. They were born to Ana and Gabe, and were raised in a rough and unbalanced environment. Their biological mother was addicted to drugs and their father was in prison. They were placed into foster care for a few years and moved around frequently. They were eventually adopted by Stef and Lena Adams Foster when they were around five-years-old after their former foster parents could no longer take care of them. The siblings were extremely close growing up, as they only had one another when they were moving around foster homes. Even as teens they remained close, even though they did argue frequently and have a few falling outs. In the end, they are each other's best friends and always have one another's back.
Callie Adams Foster - (see Callie and Mariana) Callie is Mariana's adoptive sister and one of her best friends following Jesus. Mariana was originally off-put by Callie's rough and abrasive attitude. The two had such strong, differing, personalities that they got into many arguments. When Stef and Lena decided to fully foster Callie and her younger brother, Jude, Callie was moved into Mariana's room. This led to them fighting more and simultaneously developing a deeper bond. Their biggest falling outs concerned Callie's relationship with Brandon, as well as Mariana's inability to keep a secret combined with both girls' lies. As the years passed, the girls only grew closer and referred to one another as sisters, especially after Callie was finally adopted into the family. After graduating college, the girls moved to Los Angeles and became roommates, where they currently are embarking on the next chapter of their lives. Their relationship in LA was initially similar to that of what they had in San Diego - close, bickering, yet always supporting one another. This began to change as they drifted apart, with Mariana growing closer to the clique of girls in The Coterie, while Callie yearned for a different lifestyle. They had a large falling out when old resentments came back to haunt them, including Callie's relationship with Gael Martinez despite Mariana's feelings for him. Their lies to one another reached a breaking point, especially when Callie learned that Mariana was part of a group chat called the "Coterie Bitches" that dedicated most of their time to hating on Callie. This being the metaphorical straw, Callie moved out of their apartment leaving only a letter to Mariana explaining that she will uphold her end of the lease until Mariana finds a new roommate. This strain lasted for months, as they seemed to agree that they are "sisters but not best friends." It took their personal lives crumbling for them to reconnect, and Callie to move back into the Coterie.
Tia Stephens - Mariana and Tia met through the dance team at Anchor Beach Community Charter School, where they bonded and became close friends. They practiced together in the backyard of the Adams Foster House. They formed their dance team together after Mariana and Tia left Hayley's, which brought their relationship even closer. After their team competed and won their competition, the pair drifted apart and eventually stopped being friends.
Lexi Rivera - Lexi and Mariana were best-friends years prior to Pilot and had mutual respect for one another. Lexi and Mariana's brother, Jesus, had started a secret relationship which they hid from Mariana as they knew she wouldn't understand and would be hurt. When Mariana found out about the relationship during her Quinceanera, she became angry at both of them. She explained that she was uncomfortable with the idea of her best friend and her brother dating. Lexi tried to talk with her, but Mariana refused to forgive her. They ultimately made-up, and became close once again. They remained best-friends even when Lexi had to move Honduras. They parted for the final time after Lexi moved to Honduras permanently under the pretenses that she had a boyfriend back in the country. Lexi had lied about her boyfriend to make Jesus feel better about moving on with Emma.
Isabella - Mariana placed a request with Alice for a new roommate. Alice referred Mariana to Isabella. When Isabella arrived for the introduction, they were wearing the same shirt. They quickly bonded over their mutual love for Grey's Anatomy and even had the same favorite episode - the plane crash. Mariana liked Isabella so much she disregarded her references and approved her. Isabella moved in shortly after. They bonded for the first time when Mariana vented about her boss and boyfriend.
Raj Patil - (see Mariana and Raj) Their relationship originally began as co-workers when Mariana thought he was just like the other sexist employees at Speckulate, however, they grew closer as they learned more about one another. They grew closer through their work and eventually allowed themselves to cross the line between co-workers and lovers. Mariana was initially hesitant as she didn't want people to measure her success by her relationship with Raj. She has since overcome that hesitation and he's helped her and the byte club in their efforts to make Speckulate an equal environment. They have since dated, had sex, and proclaimed their love for one another. Raj is Mariana's first serious relationship since high school.
Evan Speck - (see Mariana and Evan) They first met when Mariana was hired at Evan's company, Speckulate.

He confided in her about his personal struggles with Asperger's syndrome and how it effects his daily life. Their attraction to one another grew until they had sex, which Mariana instigated. However, her relationship with Raj Patil left her feeling conflicted over who to choose. She ultimately decided to be with Evan, though they agreed on a secret relationship for the betterment of the company and their careers.
Zac Rogers - (see Mariana and Zac) Zac was a classmate Mariana met while on the set of a school play. It is hinted that he had a crush on her. Although, she didn't initially feel the same way.

They had a short-lived relationship, with his mother suffering from Alzheimer's disease and requiring proper care. This resulted in Zac moving away to live with his father. Zac was Mariana's first boyfriend.
Mat Tan - (Mariana and Mat) Matt is a member of Brandon's band. This is how Mariana originally got to know him. The two initially bantered often, and as the two grew close, Matt, after asking for Brandon's permission, asked her out, to which she accepted. The two connected over having biological parents abandoning them and the uncomfortableness of letting someone know. Mat and Mariana then say "I love you" for the first time in Light of Day. They break up for the first time a few episodes later. They finally tell each other they still love one another in The Show.

However, after he increased his EQ and apologized, they reconciled and began to date. During their relationship, Nick repeatedly pulls out the big stops for her. Their relationship was always complicated due to Mariana's feelings for Mat, and this escalated until one day, he brought a gun to school. Mariana and Nick talk at school and she explains that she was only saying goodbye to Mat, but Nick doesn't believe her. Nick, on the loose with a gun, breaks into Mariana's house and sneaks up on Mariana with the gun. Nick is ultimately arrested. Under the belief that they are still together, Nick reaches out to Mariana by calling and texting her while he's in a mental facility. Mariana allows him to continue believing this, even though she has begun dating Mat again. Nick had insisted that Mariana was the only thing keeping him alive. Mariana was afraid of what he'd do if she ended things with him. In Collateral Damage, Nick says he understands they aren't together anymore and apologizes for how he's made her feel.
Logan Bayfield - Mariana became interested in Logan when he moved next door to her and instantly tried to win him over by acting as if she had the same interests as him. They became friends, but Mariana always wanted to be more than that. When she learned that Logan has a girlfriend she backed off and started helping him to win over his girlfriend when they were fighting. Mariana's relationship with Logan became increasingly awkward, especially after his girlfriend claimed that she liked him which forced Mariana to pretend she was in a relationship. Logan's mother, Tess, even threatened Mariana to keep her away from her son. They eventually dated for a while, however, Mariana decided that she wasn't ready to be in a committed relationship, and wanted to date other people as well as Logan.
