Glancing down at his own bright metal hand, Bucky blinked. "Never even thought about rust." Granted, the metal itself he was quite certain couldn't be damaged by a little water. But when the plates shifted as he moved, there was a possibility water could work its way in...

He shrugged, and looked back at the guy. "They never warned me to stay out of water, and I got dumped in at least one river I remember and it was fine. I was in the water with the aliens earlier and didn't have any trouble. Hopefully if something goes wrong later, the ship people can fix it."

Since the other man had started the conversation, he assumed that meant it was okay for him to ask questions without being nosy. He came closer, fascinated by how the other artificial limb could nearly pass for human. "Not sure if you're more advanced, or if they just didn't care enough to try to hide mine. It went with the rep, you know? Made me scarier, I guess."
