He is in -

- it doesn't really matter, because he's not conscious. Skipping ahead a bit, he is in a weirdly cozy doctor's office, lounging in the buff on an exam table draped in a thick sheet sort of thing, with his possessions neatly stacked on an adjacent chair. There some kind of six legged flying squirrel looking thing perched on the back of the chair and a doctor murmuring at another such squirrel.

Hm.  That's much worse than he thought this was going to go, although maybe it wouldn't have been if he'd thought about it while properly awake.

Heeeee.... reaches over for his earings??  Are they close enough that he can grab them without getting up.

Yup, they're on top of the stack of his effects.

He puts the first one in, then tries to not react to whatever he can make out of the human's muttering while he does the second.

"- contusion of the elbow but otherwise in a state of physical health not consistent with origins in - oh, hello."

- He has an idea.  "Hello."

"Where might you be from?"

"I don't... remember....."

"...what do you remember?"

Jensi attempts to look thoughtful.  And confused.

"Do you know your name?"

"What sort of words are names?"

"...let's circle back to that later." Time for a battery of cognitive tests.

Can he put his clothes on first?  Ideally without an audience?

He can put his clothes on but the doctor is not leaving. Neither are the flying chipmunks. Just when you think you've counted all the flying chipmunks in the room there turns out to be another one.

Fine.  What are the tests like?

Repeat back this list of words. Spell this other word. Draw a square. Identify the commonality between all these nouns (they're fruits). Repeat that list of words from the first exercise again. Describe this here varmint verbally. Add six and five. Mime making breakfast. Subtract nine from seven hundred and four, and then subtract it again a few more times. Draw a tree.

He can repeat the list, and spell, and draw a square, and identify that fruits are the thing in common even if he doesn't recognize all of them.  He intentionally whiffs an item on the list the second time.  The varmint is small and furry and has six legs and round-bead-like eyes; eleven.  ....He mimes receiving a sandwichish item from another person and eating it by hand.  695... 686..... 677... 668.  He sketches a deciduous tree, starting with a shaky, somewhat impressionistic outline of the leaves and hatching in some shading before sweeping down some lines for the trunk and branches.

Okay, and he still doesn't remember his name or where he came from? His family? What happens if the doctor digs up an old dialect-triangulation test to find out if he calls water fountains "bubblers" and so on to get a guess at where he learned English?

He does not.  But sure, he can take a quiz.

('The devil is beating his wife'???  Small freshwater lobsters?  The night before Halloween??)

He picks answers that contain words from the question wherever possible (a sale of unwanted items in your porch or yard: is probably a yard sale) and is vague whenever not (he uses firefly and lightning bug interchangeably; he has no word for a lot of 'this'es; he has never heard of a lot of 'such a thing's).

Wow, that's an incredibly inconclusive dialect test, though of course it's twenty years out of date so it couldn't possibly be that good anyway.

"Do you know what you want to do next? What kind of place you would like to live?" asks the doctor eventually.

"Not really."

"Okay. Do you remember about aliens?"

".....No."

"Ah-huh. - do you have any expectations about what will be outside when you leave my office. At all."
