It's the flick of her eyebrows and the tilt of her head that catches his attention, even before she's spoken. The briefest of expressions, yes, but he knows them for what they are; knows even before she speaks that things are back to normal between them, and the old familiar back and forth has picked back up. Which honestly, suits him just fine. One moment of emotional honesty is about all he has in him for one night and he's not really in the mood for another of the kinds of spats it would take for him to actually be in the right sort of mood for another besides.

And in any case, he's missed this. Not as much as he has her, but the two have always come hand in hand.

"You could, yes," he answers, and despite his words it's only really an agreement that the possibility of doing so exists. "But honestly, none of them would be able to fully appreciate the beauty of it, and it seems to me that would rather be the point of going."

To say nothing of the fact that he's well aware that the offer was made to him, in a moment that he's reasonably certain wouldn't have been shared with anyone else. Otherwise, why bother with any of what the evening has entailed thus far?

(He's not certain the offer of Vienna would have always have been on the table. But it is now, and he knows better than to assume that doesn't mean anything.)
