Sans shakes his head like a dog shaking off water as they emerge, clearly stunned by the whole thing but definitely more alert. He's barely cognizant of what just happened, mostly that it involved Tyki grabbing him in a tentacle and then everyone falling into the water. Unfortunately, Papyrus wasn't part of that.

"Hhk - Papyrus!" he wheezes. He would have teleported right that second, but he can't when Tyki is holding him. His eyes center on the healing draught, pupils worried pinpricks. He doesn't know how hurt he is, but he can't waste time debating it. He grabs the potion and quaffs it. The rush of healing energy is appreciated, what with his meager stamina, but then he immediately squirms to get away.

"Lemme go, I gotta-" He doesn't know what exactly, but he needs to get up there. He flutters his wings, trying to go upwards.
