Nightmares are actually a pretty regular occurrence for him, but he tends to keep quiet, at least enough that the sound of his disturbances doesn't carry through the walls. He's twisted and restless, blanket wound around his legs a little, tangled up enough for her to see he's in only boxers and a ratty old t-shirt. He frowns, in his sleep, and one arm twitches as if he's trying to reach out. Then he whimpers softly, an incoherent noise of protest.

This could be why he still looks a little tired and ill, even after a couple months in safety at her place.
