Jade is known for using Lilly's family just to be in the "rich kids" group. She was always so annoying then...and she still is, but I don't know if for sure if she would go out and murder kids. Granted, she was always there when something went wrong, but so was Maddie, and it turned out not to be her!! Eve was never suspected, that's why she is the killer!! She hates her sister BECAUSE of Louis raping her, she feels like Maddie stole her husband, but doesnt' know that Maddie didn't want him, and certainly didn't want to be raped!!! Eve's just pyschotic!!!!
