Potemkin just going to lie in the ruins of what used to be his bed for a moment because what the hell just happened. He alternates between staring at the ceiling in shock and giving side glances toward Sion, matching how his mind is currently going off in a dozen different directions at the same time (should he apologize? For something he wasn't even conscious of?)

"Y-y-yes, I'm fine.

Was that really me?"
