There's a twitch in his face after Rey starts to pull away, and all trace of the sheepishness from before disappears as his expression goes blank, a low ringing sounding in the air as if they'd suddenly gone deaf for a moment.

Kylo struggles to stop himself from thinking or feeling much of anything, already far too aware of the dangers in the direction any of them could go. It's because of that—and trying against Rey's request to hide the turmoil he's sure he can't keep from his eyes—that he can't bring himself to look at her, hoping for the briefest of moments that he can pretend things haven't come this far. He doesn't want to think about yet another person he's come to care for like this returning to detesting him back home, even if he won't remember it himself. And that's... without the other complications, as if there weren't enough in the first place.

But already it's too late to pretend. It doesn't mean he has any idea of how to deal with the situation, however; his mouth parts slightly in a subconscious desire to try, but his uncertainty stops any words from leaving him as his eyes flick downwards.
