He's dressed weirdly (it doesn't look like a costume, even accounting for the lack of a mask) but he doesn't look African or East Asian. It's unlikely he doesn't know any of those languages, he probably just doesn't want to talk. Despite saying a sentence in a language unlike anything Velocity ever heard.

Oh, well, nothing for it, he's been asked to keep tabs on Rider until a team gets here that can take him in and that's what he'll do --

His radio crackles and he bursts a few hundred feet ahead of Rider and slows then enough for it to work. Velocity here.

You're nearing the end of the road, Console says, the team won't get there in time. Stop his horse, try not to hurt him.

Ah, excitement!

The faster he is, the less force he can apply (and the less force he feels). He can't counter the horse's momentum, but maybe he can spook it? The tools he carries are limited to the very thin and very very light and most of that budget is used up by his skintight suit, but he's got two tinkers on his team.

He speeds all the way up until the horse is almost frozen in place, unfolds a very thin but importantly opaque square of fabric and drapes it over the horse's eyes. He can't squeeze it under the bridle when he's so sped up but it's just barely large enough to tie its corners behind the horse's ears so it'll hopefully stay in place for a few seconds before the wind blows it away.

Move away, slow back down. How does the horse deal with Sudden Temporary Blindness Handkerchief Trick? He thinks horses are supposed to be able to run blind, or something, but maybe it'll twist its leg on the sand while it can't see? Velocity is admittedly not the world's greatest expert on horses, let alone power-projected ones.

"What the fuck is your problem?" Raimon demands, reaching forward to pull the scarf off.

Mounts will run blind. Raimon actually uses this trait of theirs a lot when it's dark, and he can see and the horse can't.

Oh well, it was worth trying. What now.

Next up in his his super-small-and-light not-quite-tinkertech toolkit: ten meters of kevlar thread! If he ties the horse's front leg to its rear one - no, it will probably just tear the thread, it's got to be much stronger than a man.

He spends a few slowed-down minutes studying the horse's gait. Tying up a leg to itself while it's halfway folded... doesn't work, the way it straightens the leg will make the loop slide off... But the two front legs don't move in tandem, like he thought galloping worked, they bend and straighten out of sync with each other. So if he ties the two front legs together when they're at the closest, it might not be strong enough to tear the thread because it'd be forced to pull a bit sideways. Or the horse might stumble because it wouldn't be prepared and trying to exert enough strength even if it theoretically could.

This might not work but what the hell, it doesn't cost him anything to try. He loops the thread as many times around as he can and ties it off. He'll watch this one in slow motion so he can capitalize on any weakness.

The horse trips. Raimon pitches forward over its neck, lands hard, and gets up. He gets up and draws his dagger and advances on Velocity with his other hand held empty but like it'll be doing something in a moment. "What is your problem?" he snarls at Velocity. "What did I ever do to you? You want to fucking go? Fine! Let's fucking go! Come at me and I'll see what the weather's like in the Maelstrom but I'm not coming quietly when I never did fucking anything to you!"

That definitely sounds like a real language unlike any he's heard before!

He's going to keep his distance and speed up if Rider seems to be using any powers and, uh, repeat his litany of different languages because he has no better idea? And stop him from re-mounting the horse if he tries to, obviously.

Technically he's supposed to stay sped up to be safe until the PRT team arrives, but that would take so long.

"I don't speak any of that shit! If you wanted to talk you wouldn't've tripped my godsdamned horse when you can apparently just jog up to it, that's not what wanting to talk looks like!" He's going to try to cut the horse's legs free. It's not dead so he can channel away its fucked up ankle.

Kevlar is pretty hard to cut with a steel knife! But also he's going to speed up and take the thread back before Rider can get it. And then he'll gesture at him not to remount, and if he does anyway then he'll tie the horse again when Rider can't reach its legs.

The attempt at gesturing at him not to remount is a complete communicative failure in and of itself. Raimon does already know this asshole doesn't want him to be on the horse, but he is not inclined to cooperate. When the adventurer approaches the horse-and-rider situation again he's going to get lunged at with the dagger.

Pfft, no-one can get anywhere near him when he's sped-up. He's long gone by the time the dagger has moved a few inches, and the horse is re-tied.

...admittedly this would not be wise if Rider was a Mover or had a Shaker power or something, approaching unknown hostile capes is never safe, but he's been near him already and it wouldn't make sense for him to have the power to make horses if he could move as quickly himself.

Okay, the asshole only has one of those threads, right?

Raimon hops off this horse, strolls far enough away that they can't just be tied together, and makes a new one.

...he can untie the thread from the old horse and retie it to the new one? He knows proper knot technique and everything!

This guy is real fucking annoying.

"You wanna talk? You have something to say to me? Get someone who can cast Tongues, bitch," he snaps.

And then he's going to dismiss the horses - he does have the knack of landing on his feet from a dismissed mount - and start walking.

He can tie his legs together too! This is really annoying, he has to speed up repeatedly to get the thread off when he tries to cut it and back on every time he's walked a few steps, but he is not going to get very far.

Raimon will continue to try to stab Velocity whenever he gets a glimpse of him in reach. He's got a Liberating Command prepared but that won't destroy this fucking thread, so he's just going to be the biggest possible asspain to this asspain.

It's not exactly a fun 'what did daddy do at work today' moment but he's getting paid for this. And this man does need to be off the streets even if he hasn't managed to stab anyone, so. You're not going anywhere.

The fact that he hasn't stabbed anyone is no longer for lack of trying.

After a few minutes, a big black carriage rushes up. Four men in full-body armor and black face-concealing helmets get out, and a woman in a tight green-black dress and a scarf tied around her mouth. There's a green-black glow flickering around her hands. They all jog over to where Raimon is failing to run away.

"He speaks some language I never heard and won't admit to understanding any of mine, and" speed up, retie the thread for the hundredth time "he won't stop trying to run away, can you please foam him."

One of the men removes a kind of hose connected to his backpack. It sprays Raimon with a grayish goo that rapidly covers his body, leaving only his head free. It's hard to move against and over the next twenty seconds it rapidly settles to become as strong as rock.

"Finally. The last two hours were so bloody boring." 

Okay now he's going to try "Liberating Command!"

But this probably winds up sounding like just an impotent swear word because the resulting Escape Artist check is not high enough to make any appreciable motion towards not being foamed any more.

"Any observed powers?"

"Only the horse creation, he made a second one." The first one is crying about its broken ankle and it is a horrible sound. "And the horse didn't react until I broke its leg, he might control them? But the second horse hasn't tried to kick me yet and I think this guy would do it if he could."

Sigh. "We'll need to take in the horses for testing in case they're real. There are procedures for dealing with powers that create biological matter. We'll foam them until they can't walk, leave two troopers to guard them and send a bigger vehicle to pick them up. The rest of us will ride back to base with the detainee."
