Marvel may not know it, but it seems they're setting up their Cap to become the insta-square that DC accidentally made of Superman back in 1986 and which, 26 years later, they've never recovered from. By setting up our pal Cap as The Bad Guy In the Dorky Outfit picking on The Guy We All Related To a Few Summers Back, its more than possible they're sinking one of their own flagship guys, all before the movie is released.
Sure, the exchange is intended to sell us on the crazy dynamics of the characters that we'll see if we give our local cinema $10, but the whole exchange feels out of character for Cap, including the Cap from last summer's movie (the whole point of which was - he's generally better than that). Yes, we need a "clashing team", but... you're losing me a little here, Marvel/ Studio/ Joss. That exchange is supposed to be the response the drunk on power/ charming Stark gives to the stuffed suit SHIELD Agent, not the guy who just got unthawed after saving the Free World.
I'm a Cap fan. Don't make me regret your movie.
