The observation that the two of them would be good at exchanging looks together when around others whatever the given situation was pretty spot on. That was likely something they could connect on and maybe that could lead to other things that sparked an actual friendship. So long as they could both sort of leave the past where it belonged and keep an open mind whenever they were around each other to the chance that they might enjoy each other's company, Bucky thought it was possible. He'd first felt some hope when Tony was removing the arm before, when he'd made Bucky laugh at one point. That was sort of a turning point, and maybe the start of an opportunity for them to mend fences and get along.
Bucky was relieved to hear that Steve was back to normal -- well, normal being what normal was to him now. For Bucky, normal was the little version of Steve who'd been sitting on the counter kicking his heels against the cabinets. But he knew that version of Steve was not the norm anymore. Knowing he was healthy again, not under the threat of an asthma attack or a fever or anything else was definitely a good thing that put Bucky's mind at ease. "He's healthy, good," he said. "I guess whatever that was wore off on everyone who was affected." It'd been terrible. He'd felt like he'd been hit by the train he fell off of in the 1940's. Bucky reached up with his hand and pressed the little release plate on his shoulder port that opened it up for Tony to start the attachment when he was ready to do so.
