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.
"Well, the best way to be absolutely sure will be to take a blood sample and sequence your genes, and I will definitely do that and won't do anything I expect* to have nontrivial effects until that's done, but that will take two days and I'd like to see if we can't be faster. So I was thinking I'd show you a bunch of diagrams and you can tell me if they match how people where you're from work."
*Literally expect!>=50%. Don't worry, there aren't!>=99% about to metaphorical!be an avalanche of these.
The room has a computer with a big monitor; Met pulls up a bunch of diagrams. DNA, with its four color-coded bases and ability to unzip! The process of transcribing DNA into RNA and translating it into proteins! The digestive system! The skeleton! The retina, with its stupid layout of rods and cones and blood vessels!
Not all of this is familiar to Kyeo but in no case is he confident that he works in some other fashion.
"Alright. Well, conditional on you being basically a human, you're rather underweight and you should eat more. And I'll want to check your vitamin levels, but conveniently that's also a blood sample so it's no extra work for you."
He is promptly minus some blood.
"Next thing is your medical history. Do you have any ongoing health concerns?"
"Have you ever needed inpatient medical treatment--that's anything where you had to stay in a hospital overnight?"
"I'm afraid that didn't translate properly, do you mean a mental disability? Can you describe the symptoms you had and what the treatment was?"
"Ah." This is a doctor, he should - "I had a problem where I wanted to kiss other boys. It was a, a combination therapy."
"That . . . really didn't translate. You wanted to kiss other boys in . . . some kind of dangerous way?"
"Then, ah, what was the treatment for? Couldn't you just--look for boys who reciprocated your interest?"
