Bucky was plastic at the moment, something that had been patently introduced into his programming so that he wouldn't fight so much at the end of a mission. Three days ago, Steve had Tony up against the wall of his room. Now, he had his best friend stripping inside of it while SHIELD agents and Avengers waited, armed, just outside. Bucky didn't have any particular issue with nudity. He was just told that he was to shower and change. That he could do. Easily.

Steve might have liked being given commands but for his friend, they were necessary to get anywhere with him. Tony's blood was all over the metal hand when Bucky waited for the shower to be turned on for him. He didn't even notice.
