The poke isn't all that painful as much as it's just unexpected, enough of a jolt to pull him out of that vague, more asleep than awake state. And with that consciousness floods in the full realization of the fact that he's not home, in his own apartment, despite having no immediate evidence to the contrary. It's hard not to miss that fleeting moment, matched now by the awareness that those moments are likely to be fewer and farther between now that he's here, and as comfortable as he might be able to get it's not the same either. But, much more immediately than that existential observation, he's aware that Barbara is right up against him, that hadn't been a dream.

Not a literal one anyway. He's pretty sure that he wouldn't have migrated over to her side of the bed, generally when he's tired and he finally sleeps there's very little tossing and turning, but he can't completely rule it out. Or, possibly, she could have rolled over and gotten scooped up in his arms, because that's what he would do when he's asleep and she's (at least from his perspective) moving in toward him.

He's pulling back that arm so that he can rub his palm over his face anyway, still sleepy and muffled, but he's awake now, if still too tangled in the blankets and a bit underneath her, he's not trying to extricate himself yet.

"Sorry. Do I need to move?"
