"Um, if Feral drew his wand back then Mark might have caught fire even if Feral didn't mean him to," Bella says. "I don't know what they were fighting about, but as long as they were already fighting, biting him probably was safer."
"...Yeah, so've I. He doesn't do it on purpose. He's waiting to grow out of it," says Bella.
"Um, I don't think most people who've watched someone die killed them personally, but why are you telling me all this stuff anyway?" Bella asks.
"I'll ask him about the thestrals," suggests Bella. "Um, thanks for warning me?"
Bella hurries the rest of the way to theory, which passes uneventfully, and to transfiguration, similar, and then it's lunchtime.
Is it Feral? Bella bets it's Feral. There she plops herself. "Some girl thinks you might murder me," she says. "She thinks you can see thestrals because of having killed somebody and that it's not safe to hang around you. Also she said you bit someone, but she said he drew his wand on you so I think that was probably the best thing you could've done if you couldn't just run away because otherwise he might have caught fire and that's worse than getting bit."
Bella nods firmly. "I don't understand why the faculty is being how they are about the fire thing. I hope you grow out of it soon, it sounds awful."
"I didn't think so. How come you can see thestrals, though? I didn't ask last time it came up."
"That's what the girl said," Bella says slowly. "I didn't think it was true."
