"You mean, for the next few hours?"

"Yeah. Or, you know, whenever."

"Probably for the next few hours," he says. "I don't know how 'being a vampire' will work out for the next while since I keep finding out more things."

"Right. Okay.—I'm sorry about all of this."

"… It's still not your fault," he says, frowning.

"Yeah I know but I still regret that it's happening."

He shrugs. "Anyway, do you want to continue some tests or something?"

"...sure."

"What?"

He shakes his head. "We could test vision, now. Can you see microscopic stuff?"

"I can't see, like, bacteria and stuff, if that's what you mean? I'm not super clear on how to check if what I'm looking at is 'microscopic'."

"Dust motes? How much detail do you get on those?"

"The creepy little mites in the air? Enough to see how creepy they are."

"Okay, then yes to microscopic vision, I wonder if this extends to distance, can you see mites over there?" he points at a wall across the hall from them.

"That's really not that far away," he says. "… That's a yes."

"Okay how come you can see creepy mites over there but not bacteria over here?"

"I mean, I don't know how big bacteria are nor what in particular I should be looking for? I haven't actually seen bacteria under a microscope before, I've just seen vague diagrams of them."

"I... don't either. We might want to perform these experiments with easy access to Google, do you have a computer somewhere?" In your gigantic house, he doesn't say.

"Yeah, laptop in my room," he says. "Should I go fetch it or should we just go up there?"

Shrug.

"I will bring it down and we can go to the kitchen then," he says, and goes to fetch it.

Sadde waits for him in the kitchen.

He doesn't have to wait very long, and then Theo places the laptop on the kitchen table and plugs it in and turns it on.

"… Am I just looking up what bacteria look like or what?"

"I guess? I dunno why you'd need to know what they look like to see them but," shrug.

So he goes onto the Wikipedia page and– "It says here that they're a few micrometers long? On average? Pretty sure the dust mites aren't that small."
