Cassie was a crazy child, she would sit in the bushes in her front yard, singing dark songs. When she was 7, she took her sister out of Granite City, running past the gaurds. Allie warned her the whole way, but she ignored her, wandering farther. She fell asleep in the middle of a city and woke up only to be in Granite City. She was confused and spoke to her sister, who declined that she did anything. When she was 12, she started to befriend the strange kids, as they grew up, they never split, goth or prison-like it didn't matter. She also continued to sneak out of Granite City.
She is suspicious and dark. She's one of those people who are totally rude and mean to everyone, but is very protective about their younger sister when it is needed.
