((ooc: I figure Fury would have a slightly better idea at just how badly outmatched SHIELD would be and would arrange for some or all of the other Avengers to be called in - or maybe Sam, who was probably made an Avenger in Steve's stead, calls them in. And later on tries to find them both and points them towards the Smithsonian.))

"Maybe a few hours?" He didn't sound entirely certain, however, because he wasn't. This was because, as he admitted with an almost sheepish smile: "I think I may have slept for a time, too." Normally, that would have been an unforgivable lapse in focus, a wavering in his attentions when he was supposed to be keeping guard. But no one had come in to wake him. Maybe the punishment for that lapse would come later, but it hadn't, yet, and so he found himself enjoying these moments and this impromptu rest all the more.

Moving almost without thinking, he moved to help the other man work out the aches of hard sleep. He had an intimate knowledge of every pressure point on the human body, but when he dug the fingers of one hand into the muscles on the Soldier's back, it wasn't for the sake of causing pain, but helping ease it.

"What matters most is how you are feeling now."

The other man would need to eat and drink, soon, if he was to continue healing. If the wait dragged on much longer, he would have to seek out a meal for him.
