There are a few of us with the same name, from different timelines. Two Steves, two Tonys. [He doesn't mention outright that there are two versions of him as well - he thinks the other Bucky is still lying low around Riverview, maybe still giving out a fake name. He won't blow that for him.]

Yeah, that... sounds like the other Tony. I'm sure he's still brilliant, but he can be frustrating.
