Uhh, okay. He asked then why they were interested, and then proceeded to tell them that they shouldn't be. Brian sincerely hoped that he understood the fact that he was really only making the situation worse. Besides, it was their opinion, right? Some people weren't all that into it and that was their prerogative, but most were and that was probably due to lack of exposure. He was right, though. It was really dangerous but if all they were being taught was fluffy stuff that didn't relate to how they would defend themselves in real life, obviously they'd be more likely to turn to the dark arts.

What could Brian tell him about a patronus, though? He didn't know much about it, but he knew enough to know that he was PROBABLY not good enough at charms to do it. Especially not at twelve years old. So he said just that. "Oh. It's really advanced magic and I am most probably not going to be able to do it successfully right now. Or any time in the very near future." He was just a second year!
