Owl to Zuko
I'm not sure this is the reaction that I'm meant to be having, but I actually like you more for that.
I mean, yeah, of course the teachers aren't going to like physical violence especially with swords instead of wands or fists, but the mental image of you threatening a bully and slicing off his garments? It's priceless. Though I guess the teachers might not have really believed you when you said that you weren't intending on doing anything beyond humiliating him.
I hate bullies. Hogwarts seems more likely to have a lot of them with how the Houses are divided up, though -- from what I've heard, I think that it's easiest to say that Ravenclaw sounds the most like Beauxbatons. There are bullies here too, of course, but people tend to tattle to the teachers instead of taking care of matters themselves.
I'm glad you're being left alone, at least, but I can see how that would get in the way of being able to talk to anyone else.
