Hannah was a very interesting person, but aren't all serial killers? She was popular, pretty, smart, mentally insane and she had the perfect life. But what made her go to the dark side? Maybe it was her twin sister Courtney, who she killed. Or maybe it was her friends, Bianca, Ivy and Taylor who all had their individual problems but still managed to stay popular. It could be her family: her younger adopted sister, also named Courtney, her parents, Jack and Rachel, or maybe it was the monster inside of her, the voice that told her what to do, the teacher that gave her advice on how to kill her victims, the friend that cared for her more than her own family did. But no matter what it was, the one thing that's certain is that Hannah was a very interesting person.
