I told you I'd have reffs up soon :D here's her Backstory:
Drea and her brother are twins, her brother would always be sitting in the backyard melting bugs with magnifying glasses and this relatively disturbed their mother, so she took them to a child phycologist, Drea is diagnosed as a normal kid. Her brother is diagnosed with being a sociopath, Drea always loved her brother and at first didn't want to believe it. But she believed it when he accidentally cut her with a knife and showed no remorse or any emotion for that matter. after they turned 18 they moved to their own apartment, he wanted to hurt someone and he wanted his sister to help him "find someone who didn't deserve to live" so she went out her brother made her find 2 people that night, 1 to kill and one to torture till they begged for death itself. She found a prostitute who was begging for money, Drea whispered in her ear, "I'm so sorry, I wouldn't do this if I didn't need to." then she killed her. There was a witness, another prostitute a Friend of Drea's who Didn't recognize her. She chased after Serenity ( the cougar) and offered to give her a ride home, not knowing anything Serenity accepted. Drea didn't want her friend to be hurt but if she didn't do it her brother would. So she drove to an abandoned lot and tied Serenity to a tree with rope she whispered "blink twice when a car comes, that's the one you need to be afraid of, I son't want to hurt you." Serenity did as she was told and Suprisingly Drea's brother didn't kill her he left her basically dying in her "work clothes" (Serenity is a prostitute so use your imagination)
