It's not that Bucky is trying to hide from Steve, because he isn't. But what's going on there is... a whole layer of complicated and difficult to put into an explanation.

But this, here... he takes the cup in both hands for a moment, the warmth from it seeping into his palms as the warmth from his friend, his... (his progenitor's) older brother, warmed him in an entirely different way.

"To coming home," he echoed, raising his drink in return. And maybe his toast also has the flavor of finding home, but it is true all the same, making his voice quieter, thicker with emotion. "And friends."

He is smiling as he raises the cup to his lips for a sip, and the familiar (slightly removed, but still familiar) taste, in this company, almost makes it hard to swallow.

A deep breath into the aroma over the cup, and he grins up at Steve. Because even with the time and complications, there are ways in which Steve knows him better than he knows himself, almost. And that makes it easier to believe in Cap's faith him. And that is a lot. "Thanks. For... for knowing how things oughtta be." Shrug. He's not really all that good with words. But he suspects Steve will get it, anyway.
