Kuai's sudden movement is met with the twitch of his own pistol, keeping it trained right on Kuai's nose in case he judged the situation wrong. But there's just enough doubt to keep him from firing. Kuai's movement isn't voluntary, he sees - he must have missed it before but he too has one of those parasite strings arcing up into the sky, controlling his movements. From somewhere above, a pink feather drifts down, and yet he doesn't dare look up to seek out the distraction. People being puppeted are still as deadly as they would be otherwise. To look away might mean being speared right through the eye with one of those icicles. And wouldn't that be just the sort of irony Doflamingo would enjoy? An eye for an eye, in some sort of literal sense, as if any of this had ever been his fault just because he was the one who ran.

No, Kuai is talking and he needs to concentrate on reality even with his mind trying to sprint several extra miles at once.

"I have been all week. So have others. I can't tell what's real half the time and what isn't." He was afraid to admit it earlier but by now it's gotten hard to care. His ability to think straight is compromised and he knows it, and if this is really Kuai, he deserves the warning.
