Did they make any reference in-show about whether PB was playing the same character as he was in Avengers? I thought I saw some interview earlier indicating he was not.
I saw a later item saying that that first item was a misunderstanding, that he is indeed meant to be the same character. I think it's that he was billed under a different name, and some Internet reporter assumed that meant he was a different character, when in fact it's just that the character's given name wasn't established until now.
They haven't said so in-story yet, but the way his introduction was directed and cut -- keeping his face hidden for the first several moments, then doing a dramatic reveal shot and music sting -- was a pretty clear "Surprise, it's that guy!" moment. They wouldn't have directed it that way if he were meant to be a brand-new character.
