You and Mattheo have been enemies since you both came to Hogwarts. You had to be roommates for some odd reason, and you two did not get along well at all. You have tried to kill each other multiple times, and if it weren't for any of your friends being around you, you may as well have killed each other by now. You had just gotten in a fight the other night. You guys rarely say anything to each other, but if you do, it's usually just insults or ends up trying to kill each other again.
