Rutile hears neither a hum nor a sing, just the soft creaks and echoes of the ship settling in the water, and the low buzz of whatever machinery is still functioning somewhere in the distance. They startle at Kit's hasty reaction. "I think it burned me, or something..."

"Let me see," Rutile begins to say, reaching for Kit's hand - though unsure of what they'll actually be able to examine in such darkness - when the sounds of activity outside the room reach them. They follow Kit's gaze to the door and a scowl twists their lips. They'd known coming on board would risk drawing the Sentry's attention, but they hardly want to tempt fate.

The decision takes a tenth of a second. They reach for the stone and wrap their fingers around it; there is no heat that they can detect, though perhaps Kit is simply more sensitive to it, and with a gentle wrench of their wrist they pry it free and slip it into their pocket. "We shouldn't overstay our welcome," Rutile says wryly. "Do you see another way out?"
