Dick does huff out a breath that's almost a laugh. It's not really funny, to have been so abruptly taken out and yanked back in, he can only imagine what kind of whiplash it would be to basically blink and suddenly have weeks go by in one instant, and on the other side of it for Barbara suddenly having what must have almost felt like a stranger in bed next to her for a moment. Long enough to react instinctively, and he can hardly blame her. He's sure he didn't then either.

But it is a little comedic, yes.

"A beard, huh?" He's not sure what circumstances would have led to that, he's generally very particular about shaving, as she knows better than anyone. He reaches up, reflexively rubbing at his chin, considering. "Did it look good?"

It would be hard to deny curiosity, about things that may or may not be coming ahead of him, but yeah, he knows the protocol, as well as the general uselessness of trying to base what will or won't happen on a multiverse that spirals out into countless different directions at every moment. Barbara wouldn't even know for sure, since that was ahead of her too.

"IF you want to smack me around with a pillow just for old times' sake that's fine, just don't be offended if I sleep through it."
