Bucky shook his head. "No, we'd never met before. It was... weird, to say the least," he smiled a little.

His gaze doesn't leave the moving limbs as Garrett speaks, but before he's done stretching out, Bucky's attention goes back to the man's face. "No," he assumes Garrett's talking about the arm. "Hydra fitted me with it while holding me prisoner. It's made of a vibranium alloy. Uh, a really strong metal," because even in his world most people didn't know what vibranium was.

"You okay?" he asks, nodding towards Garrett's extra limbs. The man hasn't done anything particularly threatening yet, so Bucky assumes that's not his intent.
