"I... guess that would be a reason, sort of," acknowledges Bella. "Do we have any other classes together?" She shows him her schedule.

...No wonder he's in remedial classes. Bella snorts softly. "My roommate and his sister are in Charms with us," she volunteers.
"I guess that would make it tricky," acknowledges Bella. "Do you have a hard time getting along with your roommate?"
Bella blinks. "That sounds like a reasonable thing to do if you set things on fire in your sleep," she says, "yeah."
"If you were asleep I don't see how you could've been trying to," says Bella, "but I don't blame them for being scared."
"Isn't there a magic equivalent of an automatic sprinkler so you could wake up wet instead of surrounded by fire?"
"So basically this entire building wouldn't pass Muggle fire code," says Bella.
