For the moment, Gortash is allowing this to be as uncertain as it is. He sees the Dark Urge is working his way to some manner of conclusion, and as much as he feels tempted to say something to stop this whole thing from coming apart. But he has no idea what that something would even be at this point. So he has to trust; he has no choice. This alliance is nothing if they will not allow each other to do their own work.

So he follows him back, pulling the robe closed while they are in motion and drawing further away from the fire, but not re-tying it. He made a mistake in not saying anything. Everything in this moment feels up in the air because of this, and the nudity, the change in atmosphere, the silence, all of it leaves him feeling small in a way that does not reassure him. This isn't just about these momentary, pleasurable distractions -- it could harm the plan. And then his one mistake harms him, harms them, but it slights even their gods, and that is a good deal of weight suddenly bearing down on him.

He's waiting for the Dark Urge to let go.

When he doesn't and even when he sits, and keeps him near enough to touch but still standing, there for him to clearly see, to be shown, Enver Gortash does not know what he expected, but he will pursue it.

Whatever happens next, he bought it.

He lets the robe fall away, and it pools like shimmering ink at his feet.
