Karkat got a vague feeling he knew which charms Peter was talking about. Charms was honestly one of his better classes, given that Spanish and Latin were close to each other on the Linguistics scale it hadn't been that hard to learn the basic spells. Dragging himself to actually learn more was an effort Karkat hadn't been interested in, given his books were in English.

He crossed his arms over his chest, mulling over the hint. He wasn't an expert on magical creatures like Tavros was (and he used the term "expert" lightly, but the fact was that the Hufflepuff knew more than he did), but they'd covered centaurs in class a few months ago. What did being worthy of anything have to do with this detention?

There wasn't much else to comment on so he just sighed, starting to move away from the professor. "Let's get this Games over and done with. And just so you know, Strider, I'm not fucking kissing you to win any favors."
