The impulse is there, briefly, to smooth a hand over Cullen's hair as he drifts off. But that'd involve moving, and Alistair's starting to relax enough that he doesn't want to move.

He stays awake -- by now, it's too close to morning for him to do anything but a light doze -- and listens to Cullen breathing. He...probably could've done this from the start with no problem after all, couldn't he. Even if Cullen didn't want to be around him earlier.

That's good to know.

(Maybe once he's warmer, and Cullen's awake for the day, Alistair will see about finding that tarp for the roof. He doesn't have much else to do; that's something he can work on for a bit.)
