"I didn't think," Feral mumbles into her shoulder, "I didn't think he was there, I didn't think he'd see me, I didn't think he'd - and then I was just afraid I was gonna set him on fire - that's why I didn't turn back, I didn't know if it was just being a Thestral that was stopping me. Last time I was that scared I lit up my broom."
Charlie doesn't evince an objection when Feral makes his own outdoor sleeping arrangements and hangs around. Bella gets Feral to quiz her on Potions and lets him go through her Muggle book collection. And then he flaps away back to school and she waits out the rest of the summer and busses back.
Bella contemplates this, then decides, "It would have to be ridiculously nasty to not be worth getting rid of one of those. Especially the wild ones that can suck out souls whenever they feel like it. At least the domesticated kind only prey on a certain short list of people."
Bella thinks about this, and then says, "I bet I could find at least a few people I would trade in, particularly since Dementors kill people anyway just roaming around. I'd rather not. But people include, like, the people who decided to domesticate them and use them as prison guards. And people who are already dying of something."
"I bet it's possible to do it another way, though. We break the laws of physics all the time, and there aren't that many wizards compared to Muggles and so it wouldn't be that surprising if there was a way to do it that didn't hurt anybody that no one had run across yet."
And classes ensue fairly unremarkably. Bella is in the second level of Magizoology, which is fun, and of course all the standard courses. They learn a nifty bruise-healing potion; she makes two extra batches on her own time to keep around for when she falls down stairs or otherwise finds it useful but doesn't want to go all the way to Healer Song.
"I don't think I'd be scared if I saw a very convincing image of myself dead and knew full well what was going on. But I don't know what I'd do to it to make it funny, either. And I know I don't function very well around a real Dementor but if the boggart is bad at faking it I guess there could be something funny that could happen to it."
"Corpse in a party hat," muses Bella. "No, I think if I had that to work with I'd make it look like I'd died cartoonishly. Put it under an anvil, tongue sticking out, X's for eyes, about to pop back up as soon as the plot demands. Dementor I think I'd put in tie-dye."
"You use that excuse to get out of a considerable amount of work," snaps the teacher, "but you've had more than enough time to grow out of infantile accidental magic. If you do the exercise correctly you will experience scarcely a second of actual fear - the incantation is Ridikkulus, you must think of a way to render your fear humorous, and if Miss Swan cannot then she at least has the history of classwork to conceivably make up for it. You on the other hand -" He flicks his wand, and Feral scoots forward in front of a cupboard, and the cupboard opens.
Feral flinches back.
The Boggart goes up in flames with an unearthly scream. The cupboard does likewise, unearthly scream not included.
And Feral spins around, snarling, to give the teacher a venomous glare.
"Sure," he says. "Maybe not today, but I will. I just—" He shivers, bites his lip, and hugs her tighter. "I didn't know it was going to be that bad," he murmurs. "I thought it would be more like when the Dementor hit me - but - that was all in my head. With the Boggart, he was there. It's a whole different thing."
"It's so bad," he says. "I bet he doesn't even know, and if he does he obviously doesn't care - there's people who have real things to be scared of, things where it doesn't matter if you only see them for a second, it'll still fuck up your whole day. And some people might not even be able to guess what they are ahead of time, or they might think it's something else, or there might not be a way to make it funny to them, or if there is they might not think of it."
"Like - I'd need to get my notebooks to find a perfect example but after the thing with the memory charm he didn't like me, he spent the rest of sixth grade making little snide remarks whenever I was about to practice something, asking if I was sure it wasn't against my religion or did I want a minute to paint a protest sign against throwing signal sparks or whatever. He was very quiet about it, I could ignore it, I'm not sure anyone else heard."
