Kai does not want to do that, at least not right now. Instead, he lets himself relax into the softness and trust that he's safe for now. Nothing bad or scary is going to happen for the next few minutes, and no new surprises are going to demand his attention. He has space to breathe—and to think.
So. In the last few hours, he's been captured by man-eating monsters, found out that he can talk to them in his head and vice versa, and been told—although Kai's not sure he entirely believes it yet—that he's one of them...well, something like them. That he's not human. Oh, and he has to eat people.
That's kind of a lot to process.
Start from the beginning. Being kidnapped by Zveri was terrifying, but Kai seems to have accepted at some point that they're not going to kill him. They've had plenty of opportunities to do that, and haven't taken any of them. Besides, there's no way he's getting out of here if they decided to stop him, so they've got no reason to lie about it.
...that's a point. Would they let Kai go if he asked? He suspects the answer is 'no', but doesn't particularly want to test that right now in case it messes with the fragile feeling of safety that's letting him slow down his thoughts enough to notice them as they go past. And assuming they're telling the truth, he should probably stay long enough to eat. Humans. That's going to be fun. At least he can console himself that it won't be anyone he's met, not this far from home. Probably. He hopes.
Yeah, he's not gonna get any more processing done until that's happened. There's too much uncertainty about how the whole 'eating people' thing is going to work. How it's going to feel. If he'll be able to make himself do it or if they'll end up force-feeding him. If he'll end up discovering that he likes it, that it feels good to eat the flesh of people he thought were his own species.
Kai's shaking now, his bubble of calm gone. He feels cold, even with all the blankets.
