If Lexa wants to to trade, Jamie might not be all that opposed to the notion. Even with the other rage demon being drawn to Ruby and his demon being slowed somewhat, he's still close enough to the demon that he's feeling more heat than chill. Even the fog rolling in doesn't bother him any. He's seen that happen plenty of times back home in Scotland, and it doesn't occur to him that it might be something unusual.

He's more than a little busy fighting the demon, besides, and he circles around to avoid the demon's arm as it swings at him again, adjusting his footing as he goes to keep his balance as the ground becomes harder to see. The demon tries to move with him, but doesn't quite manage to keep up, and Jamie is able to go just fast enough that he has a momentary opening and a good shot at hitting the demon at a spot at the back of his head that he's taken advantage of before. It might not kill this one like it has the others, but if he can pull it off, it'll free him up to go and help one of the others. So he brings the sword back, swings with all his might...and throws in a insult, for good measure.

"Take that, you overgrown candle!"

It may not do much to the demon, but it gives him just a flicker of satisfaction all the same. No matter what the results are there, it's worth it.
