Evie is spotless, cop mom, Jack, Nick, all of that has been said.
Rosalie has nothing on record. Born in New York, prominent family, debutante, some page 6 type stuff.
Nina has a fake background for Nina Castel that she put together when she left LA. It shows her as a normal kid, parents were migrant workers, moves cities a lot now, no trouble with the law :D Any rumors regarding her killings talk about the Castillo girl though.
