That reply got a glance up at Barnes' face. He didn't know? Didn't know how often he needed maintenance or how long it had been? Neither option made much sense. Maybe the amnesia Rogers had mentioned. Still, in that case he'd expect an answer like "I don't remember," rather than "I don't know."

Whatever. Tony let it slide.

"I'm guessing a month is a long time," he said dryly.

Apparently satisfied with whatever he was seeing at the elbow, Tony moved to the now ungloved hand. After "grip strength unaffected" he hesitated just slightly before inspecting it, but Barnes had let him get this far so he could probably trust the guy not to break his fingers. Nevertheless, it was with a slightly careful touch that Tony bent the metal wrist to watch how the plates glided and interlocked so smoothly in such a complicated joint. Damn him but this thing was cool. Tony let out a breath through his mouth.

"Okay, I'm impressed," he said with grudging respect. He glanced at the pile of tools and grabbed a screwdriver with his free hand. Time to get to the real work.

"How's a guy like you get a piece of tech like this, anyway?"
