Thor lets out a hum, trying to figure out what he feels other than the sharp pain of the cold. It's not as painful physically as Nidavellir had been or the Power Stone. That might have been why he was utterly convinced he could take it. Whether or not his body would appreciate his stubbornness was still yet to be seen.

Thor gestures at himself with the dagger in typical casual Thor recklessness. "I can still feel my heart beating if that's what you're worried about," he says, as if that's some assurance to Loki.
