Maybe it was part of that craziness last week. Talking goats seem just as likely to happen as him being nice.

Well let's be honest here, you said so yourself up there. Fighting isn't allowed in Hogwarts, and for pretty damn good reasons too. Kids who think too much of themselves could get hurt real bad. Might have nightmares about it, aside from the cuts and bruises. Besides, the professors wouldn't want to deal with angry mums and dads asking why their kids got beat up in a club activity.

It's too soon after the Wizarding War for fights at school anyway. Not saying the fight club is wrong, but if there's no teacher around to check that students don't get out of hand, things could take a turn for the worse.
