"What if he makes more horses inside the van," wonders one of the men.

Hmm. Foaming his head might stop him from being able to aim or to use his power. On the other hand, being unable to see might lead him to make a horse and squish them all because of not realizing he's in a confined space.

"Leave him alone in the back of the van to minimize the risk," she decides. "I'll ride up front and Velocity will accompany us outside, the rest of you stay here."

They have to arrest many strange parahumans and they can't keep them unconscious all the time. If he's going to make horses offensively, it's probably better to learn that now rather than later when he's inside the building.

They carry him into the back of the carriage (the hardened foam can be handled safely), restrain him to the wall and close the doors. A few minutes later the carriage starts making noises and accelerates.

He dismisses the horses during this process.

They weren't fully foamed, so this gets noticed!

"So they weren't real after all. Must be a range limit." This is good news because it means they don't have to run the biological safety tests. ...or at least they can't run them until Horseman makes some more horses.

"Or he has a cap on how many he can make and is preparing to make some more," says Velocity as he jogs alongside the van.

"He didn't have eyes on them when they disappeared. I hope he can't make them without line of sight, or he might be hard to contain." Spamming horses into a secure holding area isn't a serious security threat now that they know to expect it, but it could become extremely annoying.

After driving for at least half an hour, the carriage stops in an enclosed space filled with other carriages. The troopers blindfold Raimon and carry him to a little prisoner-transport-cart, which they will roll through a maze of passages and into a little empty room that they spend a minute in and then back out and through more passages and into a prison cell. 

Well, he's going to do his best to bite anyone approaching his head, but he can't really do that very well right now.

It is possible to blindfold bitey people! (Ask them how they know.)

Once he's in the cell they'll spray a little foam dissolver carefully so they can get his dagger away from him without him being able to stab anyone in the process. And then they'll remove his blindfold, lock him in, and spray a lot of foam dissolver from the ceiling sprinkler, and then a lot more warm water. The cells has grates for it to run down, like a big shower stall.

At the end of this process Raimon is free, clean, and soaking wet. Any paper and such that he may have had on him is probably ruined.

His bag of mail didn't come with him on this misadventure, so no big deal.

Detect Poison.

He is not poisoned. Some of the things in the cell would be poisonous if he ate them, including the remnants of the foamy water.

After half a minute, a guard comes by to slide through the mailbox-y slot in the door:

- A towel

- A folded set of dry clothes in approximately his size

- A rectangular plate made from some strange material, containing two objects wrapped in what might be paper and smelling of bread and some other, less familiar things (they are Not Poison)

- An empty cup

- A toothbrush of likewise unfamiliar material, and a red-and-white tube from which a white paste can be extruded (Not Poison unless he eats the whole tube)

- A blanket

He'll have to actively take some of these things from the shelf in front of the door so the guard can pass the rest through.

Other than the door with a window in it, the room contains:

- A flush toilet and a sink with a water faucet (the handles that operate these may not be obvious)

- A curtain which can be drawn to ostensibly cut line-of-sight between the door and the toilet

- A bed (waterproof and almost dry)

- A little desk and chair for e.g. eating

- A couple of empty shelves

- A number of gadgets in the ceiling and walls whose purpose is not obvious

This is a swanky prison, which miiiiight or might not bode well. He'll take the stuff. He's not going to change into the clothes right away. He's been wet before. Detect Poison doesn't really care about dose dependency and he attempts to push the toothpaste back. Everything else he'll take even when it's confusing.

He is allowed to refuse toothpaste. If he pushes it back through they'll take it away.

After they confirm he can't or won't speak English, Spanish and a few other common languages they'll leave him alone for the rest of the night. (The room is brightly lit; it was not a design consideration that someone might be unable to find the light switch.)

They won't come for him right away next morning because Armsmaster is busy, and then he is busy with a different thing that the in-building hospital is also busy with, and then...

By the time somebody does come it's over two hours past dawn, and dawn is relatively late in the day this time of year.

Raimon can in fact sleep in bright light. It doesn't make any difference to whether he can see his surroundings.

He sleeps. (He changes into the dry pants eventually, but he keeps his shirt. He can cast off the embroidery on the sleeve cuffs even though it's homemade and hard to recognize if you're not looking for it - Calistria's an assassin's goddess as much as anything else, and She gets the picture. They haven't taken his holy symbol yet but they could get it into their heads any moment.)

When dawn hits he prays. All these assholes have it coming, Calistria.

Right then.

If they're going to keep holding him they would like to do a routine medical examination. (They will not in fact like this, but they are legally liable if he came in with treatable injuries or diseases and they miss them, and that shirt looks iffy.) However, given the lack of communication and the biteyness, it can be postponed for now.

Two men in full plate come up to his door. One raps on the door to get his attention. "Can you understand me?" he demands. "¿Hablas inglés, puedes entenderme?" He'll go through a few more languages briskly.

The other one would like to know how Rider feels about this!

He feels like these are the biggest fucking idiots in the world. Like, wait for him to cast his Comprehend Languages first. He didn't speak it yesterday so if they think he might speak it today that's the only way it's going to happen! He only has one of it so they'd better be about to make it good.

"Comprehend Languages." Sarcastic inviting gesture.

Armsmaster continues repeating "Can you understand me" in a bunch of languages.

"He's exasperated. Sarcastic. Feels superior, maybe."

Raimon makes a rude gesture at Gallant. To Armsmaster he says, "I just cast Comprehend Languages. Do you have anything else to say."

Whatever he's saying, he doesn't think he's lying. (This goes over comms to Gallant's helmet, because his truth-detector is still secret and also experimental.)

He will continue trying languages! After that he'll try repeating them, interleaved with plausible-sounding but nonsense strings of sounds, and see if he or Gallant can pick up on any differences in reaction.

"Gods, what a fucking waste of time," Raimon says, rolling his eyes when he starts speaking nonsense. "It lasts ten minutes. Whatever is so important you'd better hurry up with it."

Was that a different reaction to the gibberish, can he elicit it again? 

Armsmaster also doesn't want to spend more than ten minutes here!

"Bitch do you have anything to say to me or are you just trying to figure out if you can make me discover that I miraculously speak fucking Arcadian?"
