He's just glad it's dark enough down here that his blush is probably not visible, because that's just what this situation needs, right, a discussion of his inappropriate reaction to bloodbending, that'll help and will not in any way make the whole fucked-up situation ten times more awkward.
"Um. Thanks. I think I'm good now," he says.
So Dao goes upstairs. With the bone-stealing serial killer walking silently behind him. Which on the one hand is totally unfair and not something any reasonable person should have to do, and on the other hand, he's pretty sure he's genuinely less scared of this guy than this guy is of him.
It's a small house, and every curtain or shutter on every window is firmly closed with only a tiny bit of morning sunlight leaking in around the edges, and the furniture is sparse and not well-organized. It looks... lonely and sad.
But instead, something occurs to him: "Hey, um, what's your name? Or. A name, I don't care if it's like, your real one or whatever, I just," he shrugs.
"...I'm sorry I kidnapped you," says Spider, very quickly and quietly, like he's afraid of the words.
The kitchen is as sad and lonely as the rest of the house. Dao finds the most uncomplicated breakfast food available, and sits down with it. He is dizzy and tired and hungry but at least one of those things is about to be solved.
It's creepy and weird but, when he considers what he knows about Spider, also perfectly understandable. Unfortunately that doesn't tell him what to do about it. He finishes eating and asks, "Is there somewhere I can sleep...?"
"Yes." There is, rather inexplicably considering Spider's blatant and extreme discomfort with other people, an impeccably tidy little guest room.
He's not sure how long he sleeps for, but the room is a lot brighter when he gets up. He sits on the edge of the bed for a bit, and then feels a vague obligation to straighten things up in memory of how immaculately tidy the room was when he got here, so he does that, and then he sits on the edge of the bed again and feels very awkward.
Spider is quiet.
Dao waits until after lunch before he says, "So do you like... want to sit down somewhere and talk about stuff? With optional hugs?"
They do that. Spider doesn't quite collapse into a small miserable lump, but he does lean on Dao quite a bit.
