He's awake, sort of; he's curled up around a pillow with one eye open, looking over his shoulder at Lev. 

"Hey, kid," he says in Russian. "Are you okay? Do you need anything?"

"I think I'm okay. Food would be good." 

"Let's go find you something." He thinks about how to explain Jarvis to a person from an unknown world. "Do you know what a computer is?"

"I've never used one but they exist." 

"There's a computer who's a person in the walls and he speaks Russian and if you need anything you can talk to him." He keeps his voice quiet and gentle.

"I do speak Russian," Jarvis confirms.

Sasha isn't sure whether he believes in computers that are people, but. ".....I guess I didn't believe in magic once. Hi. Do you have a name?" 

"My name is Jarvis," Jarvis says. "Do you know what kind of food you want? I can bring it to you."

He thinks about it. 

"Just something that'll keep me full for a while." 

Then a little robot will come knocking on his door carrying an unopened rectangle of cheese and a loaf of bread and assorted fruits and vegetables.

"Thank you," he says, and takes the food and eats it. 

"I am married to a you in a different world," Lev says.

"....okay?" 

"I thought I should probably say that. --What is your world like?"

"....it has magic in it? We have computers but they aren't nearly good enough for Jarvis to exist? People write a lot about robots but they aren't real? — I guess I thought magic wasn't real either but you know." 

"Is it an Earth? Like--" He takes out his phone and shows Sasha a map of his earth. 

"Yes, it's that. I'm from the Soviet Union but my family and I got out a few months ago and now I go to a magic school in England because apparently I'm magic." 

"What year is it?"

(He tries, as best as he can, to be reassuring.)

"It's November of 1988." 

"That's fifty years earlier than my world! Cool. You can do magic?"

"Yeah. — I'm not very good at it. I'm kind of stupid and they only teach in English." 

He knows two facts about this school and he is already incredibly pissed off about it.

"I've met the other yous and I'd be pretty surprised if you were stupid."

"I mean, it's not helping or anything that I can't sleep and don't speak English but I was dumb even before." 

"...Why can't you sleep?"

"The dorms aren't safe because I'm a —" and he repeats the word mudblood, mimics the tone as well as he can. "And when I tried sleeping in the common room instead someone tipped the chair over. I can get enough to be okay in free periods and things but it's not great."
