Good Trouble Wiki
I barely remember a time when I wasn’t the sick girl. And you never looked at me like that. Which is one of my favorite things about us. I didn’t want to change what we had.
Grace to Brandon

Grace Mullen was a recurring character on the Freeform series, The Fosters. Grace was a volunteer at the hospital who helps kids with autism by communicating with them through music. Recently, Grace's leukemia returned, but her treatment failed. She made her first appearance in Doors and Windows.

Grace was portrayed by Meg DeLacy.


When Grace was nine years old, she became sick and had to be admitted to the hospital. The doctors diagnosed her with leukemia and, as a result, she had to begin chemotherapy. Grace was put later into remission and declared cancer-free. When she was thirteen, her cancer seemingly returned, and she restarted chemo. Grace also was able to participate in clinical trials and went into remission for the second time.


Grace was an old and beautiful soul, who wanted to help people with autism get better. She was originally closed hearted due to not wanting to open up to anyone because of her illness, but she later fell in love with Brandon. She was adventurous, daring, and worked every day to face her fears no matter how crazy they may have been. Grace was also exceptionally kind and fun-loving, adjusting to any situation she was put in and making the best out of it. She was also good with children. Despite having a life-threatening illness, Grace remained vibrant and seemingly happy toward the end of her young life.
