It's as good a suggestion as any other, and much along the lines of what Steve was thinking of. The last remark surprises him more, though, and when she looks back she likely won't miss the flustered look on his face, even if the dark of the night mostly hides the blush. He finds himself hoping with all his might that no one will come out here while Natasha is climbing up or down the wall, he'd be mortified to have to do something like... that.

He keeps his eyes on her for a moment longer, impressed she manages to zip up the eight floors in such a short time. Eventually he looks back out over the city, feigning a sip from his already empty glass, trying to look as inconspicuous as can be as he glances back in at the party. Luckily the Senator's still there, not showing any signs that he plans to leave. Hopefully it'll stay that way.
