Thor raises a hand, though he doesn't try to take the bottle away. It hovers there in the air for a moment, as if he's not entirely sure what to do with it before letting it rest on the back of Loki's head.

He lets it run down the curve of his neck and stop on his shoulder where he gives him two pats on the shoulder.

I'll stop, he mouths at him, when Loki finally looks at him.
