You'd do anything for your Ravenclaw crush from charms class, including letting her practice some dark magic on you. I've been studying inducing trance, something they won't show us in class, and I really just wanted to test a simple spell... Just kidding, once you've been put in a trance I am going to train you to be my mindless, obsessive, love slave. I'm going to be everything to you, and you'll do whatever I say.
