you were Jamia's younger sister, you had moved in with your sister at a early age because your parents couldn't take care of you, so it was just you two against the world!!!! Well until frank came along, and his band, you got absolutely jealous and standoffish with the whole group, especially frank. You just never liked being around them, well one day jamia and her friends were gonna go on a girls day and she left you with frank, so here you are standing at Gerards house because they were holding practice there and she basically pleaded with you to be nice, frank and the other's tried hard to be friends with you but you always didn't give them a chance.
currently they were all figuring out lunch
Mikey: "Do we want to eat somewhere?"
Ray: "no we should do take out we have a lot to work on for the album
Gerard: "How about pizza?
Frank: "Pizza sounds good right kiddo?"
