Stella

— She's running a lot despite her prosthetic leg. She dreams to be a champion in athletics and puts a lot of effort in this goal.

— She likes collecting pins and hair clips. She has two complete boxes of them hidden under her bed.

— She is a bit chubby, she tends to eat a bit too much. She dislikes junk food and is trying to keep a vegetarian diet (however she likes eating meat, so yeah, we can say she is flexitarian).
