Aly Teri is the younger brother of Jamie Teri and the daughter of Lise Teri. She goes to school at P.S. 510, where her mother teaches, and loves biking, gymnastics, and bagels. Aly lives in Queens with her family. Her father left them when she was six. Aly never expected she would end up in a car crash, but when it happened, it ended up changing the way she looked at the world around her forever. She was treated by Dr. J.M. Gemina after the accident, and nearly died during a testing of a new simulation therapy method.

"Jamie... this isn't real."
