Complete Monster: After escaping hell, Mary Lou Maloney kills a janitor who was one of her ex boyfriends. She seduces a teenage boy named Alexander, who already has a girlfriend, and kills a teacher for giving Alexander bad grades, and puts a strain on his relationship with Sarah, and kills a guidance counselor for being suspicious. Mary later kills Alex's rival Andrew, which prompts Alex to reject Mary. In retaliation, she kills his best friend Shane and frames him. When Alex rejects Mary again, she plans to kill Sarah at the prom. When Alex rushes to save her, Mary agrees to spare her, if he goes to hell with her and be her prom king for eternity. When Sarah seemingly manages to rescue Alex, Mary gives them both a false Hope Spot before killing Sarah.
