"Tell me when you're done permanently! And if it'll take forever I'll just go home."

"We're not sure how long it'll take, we're testing the properties of my blood!"

"Ugh," she says in a normal volume.

"You can watch the TV if you want!"

The sounds of the TV can be faintly heard a few seconds after that.

"And the intervening time, what should we do?" He looks at Sadde. "Or are you, uh. Too busy."

"I am not currently incapable of doing things."

Matt can stifle his giggles. That's a thing he'll do.

"If you say so," allows Theo. "I haven't tested my brain all that much yet – we did memory tests."

"I don't know what's so funny, you've seen my 'o' face before," he snarks at Matt, then looks at Theo. "Got anything in mind?"

That really doesn't help Matt to stop laughing.

"I'd suggest an IQ test but I'd basically be cheating with the time constraints, and I haven't done much mental math – never really liked it all that much, still kinda weird to do it – but that's presumably upgraded similarly, and, uh, things like working out where a projectile will hit, throwing balls and stuff, I was good at that as a human and that's presumably also been upgraded but I'm not coming up with any sudden tests for higher precision than 'yeah it's pretty good'."

"And higher precision tests are pretty boring."

Shrug. "I mean, yeah, but– we could go to some big field, have me throw a baseball quite a ways, then run to stand where I expect it to land? Might be kinda boring, but it could give an idea of how much it's improved, since I assume it has."

"Makes sense. But it's another test that has to wait for the evening."

"Yep, but the mental math things – I mean, I don't really need you to help me set up an experiment, I don't know why I haven't done it yet, I can just go use the computer to flick math questions at me quickly – I could go test them now for curiosity's sake and to waste a few minutes?"

"Sounds good," he shrugs.

So he goes to his laptop and brings up a site that will flick random math questions at him!

… He's quite a lot better than he was before. Not an absolutely absurd amount better, but enough that he does have to complete a captcha after a few of them to confirm he's not a bot.

"New captcha: are you a vampire? Please click on the pictures from this list that are actually food: hamburger, carrots, a woman, salmon, and a baby."

"Heh," responds Theo, slightly half-heartedly. "But I think captchas are usually to distinguish machines from humans."

"Yes. That is indeed what the joke was about."

"Yeah."

"...sorry."

He shrugs. "I don't want it to just– slip my mind again."

"It won't, we'll make sure of it."
