Clearly Bucky's not in the running to be the world's best husband at the moment. He does want Zemo to talk but he doesn't know what to say in response. He's either abrasive or dismissive or not responsive enough or just-- been alone for too long that doing anything more than just listening and observing is a surefire way to get in trouble.

He watches Zemo get dressed and his frown deepens. For a moment he thinks maybe he should slink back to his own room and curl up on the floorboards. But then he's not sure if that is going to be worse than just lying here. He doesn't think it would be good for Zemo to be alone through this.

"Can I-- hold you tonight? At least?" He's not trying his luck, he just wants Zemo to let him be protective without Zemo feeling like Bucky thinks he's so fragile.
