It just made me feel so hopeless. Like I was never going to be normal.

Sophia Quinn is the daughter of Robert and Jill Quinn and the paternal younger half-sister of Callie Adams Foster. She first appeared in Things Unknown.

After getting to know Callie, Sophia immediately grew attached to her and expressed how she wished her family could adopt her. In later episodes, once her true suicidal feelings are brought to light, Sophia is diagnosed with a personality disorder. She is subsequently entered into professional help and begins making positive progress.

Sophia is portrayed by Bailee Madison.

Physical Appearance

Sophia has fair skin, wavy brown hair, and brown eyes. She bears a striking resemblance to her half-sister, Callie. Sophia's fashion style is very high-maintenance and girly, consisting of skirts, blouses, dresses, and tights. She wears a lot of bright-colored clothing, such as pinks, yellows, purples, and blues.


Sophia appears to be an open-minded, opinionated, outgoing, cheerful and bubbly young girl. She was excited to get to know Jude and especially Callie, delighted at the prospect of having a sister.

However, Sophia has demonstrated suicidal tendencies along with desperately craving Callie's approval shortly after learning of her existence and personally meeting her. This is displayed in Over Under when Sophia responded to Callie's refusal to forgive her for sabotaging the latter's adoption process by the Fosters by walking straight into traffic - almost getting hit by a car and causing it to crash into another to avoid hitting her. In Someone's Little Sister, Sophia appeared to attempt to drown herself when Callie called her "a spoiled brat".

Callie soon admits to Sophia's parents that the car crash she caused was not an accident, to which Sophia admits her suicidal thoughts, much to her parents' devastation. In Light of Day, she is mentioned to be in a mental health facility and is believed by the doctors to have a personality disorder. Sophia soon returns home in the Season 2 finale, where she admits to feeling good again, but has insecurities regarding her mental disorder.

Someone's Little Sister
Sophia and her family agree to host a fundraiser for Girls United at their home. Sophia objects when her parents and Callie decide to only mention Callie as a 'friend', and asks if Callie can spend the night at their house the night before the fundraiser. The Quinns agree, and the night before the party, the girls bond, talking, and even sharing Sophia's bed. After Callie gives a speech revealing that Robert is her father and Sophia is her sister, Sophia pulls her aside, telling her that she has taken Callie's abandonment papers out of the mail, and has destroyed them, telling her that it's not too late for them to be a family. Callie becomes angry, calling Sophia an "spoiled brat", and runs out. Sophia, visibly upset, locks herself in the bathroom.

Over Under
Sophia attempts to drown herself in the bathroom. When her parents try to get custody of Callie, she goes with them to the judge and seems hurt when Callie says she doesn't want to see her. Later, Sophia goes to Callie's work to apologize, but Callie says, "There is nothing she could say to make her forgive her". Sophia responds saying that if Callie doesn't forgive her, she'd kill herself, but Callie thinks Sophia is being melodramatic. She walks into the traffic and almost gets hit by a car. When Sophia's parents come, she tells them she walked in the traffic by accident, but Callie tells them that Sophia tried to kill herself. She then admits to her parents that "sometimes she just wants to die" and that "she doesn't think she can do this anymore".
