There's a bit of a smile at that insistence. They should, really. If this doesn't last, or they track down one of Bucky's contacts to fix this predicament... well, people are going to think Bucky is certifiable, marrying Zemo of all people. But Zemo isn't feeling particularly inclined towards it, now that he's had time to cool off.

And maybe the time out in isolation did give him time to think, even if it equally drove him insane. Bucky had enjoyed it though, and Zemo hadn't had any embarrassing bouts of anxiety when the walls felt like they were a bit too close to closing in.

It certainly prevented Zemo giving into the irrational urge to disappear for a bit -- something in retrospect seems like it would have harmed Bucky far more than he'd have truly liked.

"Why don't you tell me, James?" Because even Zemo may be feeling a bit... awkward, actually. He isn't prone to shame or embarrassment, but this is all very overwhelming territory. Not quite like surprising his wife with a new item for her collection after being away for just shy of too long or accompanying her on shopping trips.
