His glance back at Dean is not unsympathetic. A little equally tired. It isn't only about him. He doesn't feel it's Dean's problem to shoulder, either. This. Jo has made her stance clear. Often that's all there is to it. As far as he's concerned, Dean's done enough by defending him in the first place.

Now isn't the time to get into it, though. So a look is all Dean receives. A look, and the faintest sharpening of his gaze towards her when she says, At least he's not stupid. It is a quick, almost protective, flash. Then it's gone.

"Play or don't. I've made no threat towards you. I owe you nothing more. It's not my job to placate every passing human who deems the colour of my eyes too monstrous for their sensibilities."
