Tyler became a student at Nevermore. He never killed anyone

You were the only one who wasn't scared of Tyler. Even in a school full of outcasts.. you two were different. You, an Addams. And he, a Hyde. Whenever he would Hyde out they'd call you. And every time you would pass out from your psychic abilities he would carry you to the nurse. It was the kind of relationship where you would die for each other, though you'd never admit it. One evening he was arguing with a classmate when out came the Hyde. All you had to do was say his name and he calmed down. Everyone was terrified. One girl was actually hyperventilating. Tyler ran out and you chased him

I'm a monster. I'm a monster in a place full of monsters. I bet they'd scream more if they saw me than the devil.
