Kyeo's head hurts very badly. He doesn't remember how he got that way but he can guess that he's taken a blow to the head. That doesn't explain why he's not on a spaceship any more but he should probably not expect to figure that out right now. He looks confusedly at the non-spaceship around him for a minute before closing his eyes.
"I'm... a human... from Ibyabek, which I don't think is in this system, because the other inhabited planets in that one speak a related language."
"A few dozen planets and a few tens of stars? For a hundred-odd years, some of them. Except Earth, where humans came from."
"In Earth years?"
"Two thousand one hundred something."
"That's the standard Earth year."
"I'm not actually sure what Earth counts from. Ibyabek counts from independence."
"I... think the moon landing was in nineteen-something."
"Okay, so that would put you . . . roughly a hundred and fifty years into the future? That's not too inconsistent with your number of planets. Assuming you aren't making all of this up for some reason. I have no particular reason to think you're lying except that time travel is very implausible but if you have more evidence I want it."
"...where is my sidearm? It's dangerous if you don't know how to use it."
"- I don't believe I should explain. Just leave it in the bag and it will be fine."
"I don't have one of those."
"Did you lose it in the time travel or do you have something else--wait, did they get braincomputers working, I super hope they got braincomputers working! That's really unlikely to be backcompatible, though, let me get you one of the spares for people who were in hangglider accidents or similar."
He takes his handcomp back and types into it a bunch, then hands it back so it can translate more. "Linguist and spare are on their way, in the other order. While we wait you can ask me questions about the past--ooh, and write down everything you remember about the future before you forget any of it!"
"This is Earth?"
"They're not necessary for ship duty. Recursively nonpublic?"
