Oh I like that joke about Gryffindors. I always figured the rest of us kept you around just for things like handling trolls and maybe stray dragons.

I want to know the answer to Draco's question about the troll. It's not just a mudblood who could've been killed. What if a student had gone out to the loo from the feast? I mean, yes, they'd have had a wand, but they'd have been all alone and the troll would've taken them by surprise. If I'm going to have to worry about trolls walking around the castle I think I'd like to know so I can learn some new spells.
