"Yeah, let you in and then let you fall straight to the basement," he says. "Were there any skeletons of previous descendants down there?"
"The only thing in the room was a weird sourceless probably-magic glow, and the book and the hex."
"Great, now I'm imagining that the floor down there eats skeletons," he says. "...Stop me if I'm creeping you out."
Bella laughed. "I don't think so. I think Elias Frobisher just didn't have a lot of descendants who happened to wander into the house. It's a two-story fall - it could kill me if I dove headfirst, but it wouldn't be too likely." She shrugged. "For practical reasons he wasn't really concerned about being injured, himself - maybe the point of the fall is specifically so what happened to me was possible."
"Well, it's definitely one way to make sure whoever finds the book would use it," he says, rubbing the back of his head and looking half-suspiciously, half-admiringly at the chimney.
"It does seem like it could backfire, though. Anyone can use the coin and there was only the one in there. I could have wasted it fixing my leg if I'd been a slightly different person." She glances at her backpack, currently on the floor. "I guess that's what the stash is for."
A little bit maniacally.
Bella laughs, and laughs, and laughs, and bites her own hand to keep from laughing, and a triangle appears between her first and middle fingers.
This just sends Bella into another paroxysm of giggles. She gets another triangle out of biting her hand, then chomps harder and gets a square.
Where'd he put that notebook she gave him? He gets up to look for it.
Bella watches this with interest, releasing her hand from her teeth. She puts the coins in her pocket, which now contains enough that the glow is visible through the material. She frowns at this, and then puts her accumulation in the thicker backpack.
"So," he says, digging in the laundry drifts near the chimney, "will it creep you out if I say it's kinda hot when you do that?"
"Nah," Bella says. "It would only escalate to creepitude if you started swatting me without me signing up for that - whether you were doing it because it's hot or to try to steal the coins or because I annoyed you or whatever."
There it is! As he predicted, under a couple of shirts that he kicked aside while he was clearing a path to the desk for Bella. He holds it up triumphantly, then swings by the desk to grab a pen.
Bella cranes her neck slightly so she'll be able to see what he writes, but if he's not interested in showing her she's not going to make a fuss.
He looks between the desk and the bed for a moment, and then takes option c) none of the above and sits on the floor at her feet.
"Mm-hm. If you don't mind." Bella peers over his shoulder.
At the top of the very first page of the notebook, he writes: but why is it hot?
Bella mulls over whether to be helpful. He doesn't have any practice at this yet. "Would it be hot if I did the same things and no coins happened? Or if the coins happened some other way?"
So that's two lines dropping down from the main topic. At the end of one he writes: you were laughing; at the end of the other, his pen pauses. Then he goes back up and draws a third line. The two other subpoints, apparently, are it hurt and you're gonna take over the world.
He goes back and crosses out 'laughing', replacing it with having fun for a more general case. Then he circles 'you're gonna take over the world' and draws a question mark beside it.
