Isabella's diaz. Brian O'Connor's sister. I know... diaz? O'Connor? how are they related? after their parents died in a car crash they both handled it very differently. Isabella took her mother's last name and went into the life of cars and crime while Brian did the exact opposite. keeping his father's name and becoming a cop. When isabella or izzy as Brian calls her turned 15 she ran away with nothing but a note left for Brian to find. They stayed out of each other's way. That is till Brian had to go after Dominic toretto. What's izzy's story? How did she meet Dominic? Now that Brian is here, what changes? what will izzy do now?
