The angel gently combs his fingers through Crowley's hair, gentle and methodical, simply because he knows the demon likes it. It brings him peace. It comforts him to be able to do so, to know the things that are real.

The offer makes him smile, faint existencially tired as the expression might be. "I suppose we might not get any more sleep for a while. Unless you want to, of course." He's had enough of it for now. The exhaustion he feels can't really be fought off by sleep, if he's feeling it to begin with.

Leans in, gently pressing his lips under Crowley's eye, before gently pulling away only far enough so he can sit. No polite fussing or anything of the sort, not for the idea of pampering or selfish comfort, just something to pass the time. They could well just sit there and talk, about anything else but the elephant in the room, and he'd be mighty happy with that.

He rubs his back with his hand and takes a long, deep breath, sighing as he exhales.
