It’s wasn’t Thornhill per-say who gave Enid her scars. That had Tyler written all over it. But he was manipulated and controlled by Thornhill. She was the mastermind, and you were the scapegoat.

Being the daughter of Thornhill who continued to go to Nevermore Academy after the whole incident with her and Crackstone was a death wish. Why didn’t you transfer? Because of your mother’s actions you became the prime victim for bullying. And Enid wouldn’t allow that.

“What do you think you’re doing?!” She practically growls at another pack of werewolves, claws unsheathing to prove that she’s not messing around. She stands protectively in front of you after catching them pushing you into your locker and giving you a few scratches with their claws. “Try that again and I’ll rip off your tails!”

It’s seems that her bubbly and sweet personality has disappeared, leaving a protective and dangerous werewolf.
