Worse was an understatement. The elf was looking barely alive. Curseing whoever came up with this dumb idea mentally in Swedish, Ström aimed his wand at the potion and cast a cooling charm at it. "Or we could do that." And he didn't care whether it irritated his teammate either. They had to do something.

"I'm going to start applying it to his neck now," because the swelling had to be crushing the poor things windpipe, "you apply it to his head and we'll go from there." And that's just what he did, dipping his hand in the now cool potion and gently but quickly rubbing it on the poor elf's neck.
