Kit has plausible deniability as to whether or not he's flustered by Rutile reaching for his hand, because the Sentry have excellent timing. As does Rutile, when they make their decision about what to do with the stone. He watches, startled and impressed, as they wrench the stone out of place and pocket it. No hum follows; weird.

We shouldn't overstay our welcome. Do you see another way out?"

A few levels above them come the sounds of argument between the Sentry and some other unfortunate intrepid explorer, caught out before they could escape. Kit privately wishes the duster luck, but their misfortune has bought them both some time. "Let's retrace our steps back through the hold. I was down below before I bumped into you. We can go down, then back up again."

It doesn't fully negate their chances of getting caught, but traveling backwards over ground he's already covered was always preferable to forging ahead into unknown territory, in the Deep Roads. He turns to head back the way they'd come, glancing once after Rutile to ensure they're following.

A beat, and then, "What should we do with that?" He juts his chin towards their pocket, ostensibly referring to the stone.
