Q: Tony Stark likes to be in charge but things have shifted to Captain America being more in charge. What is Tony's take on that?
A: There are really only two relationships in Tony's life in which he's been willing to assume a lower status and one's with Pepper obviously, equal footing, and the other is with Cap. It's always whoever does the job best should probably do that job and Tony's bringing a lot to the table and Cap has the most experience. It's also nice to feel like there's someone under whose tutelage you become better at what you have to do and no one's more battle-seasoned than Cap.
答：Historically, Captain America is a little better suited to giving commands, but it is just kind of like at home with my wife.
I think Joss set it up this way after what happened in the first Avengers, there is respect that comes, where Tony kind of naturally tranfers the authority to the most capable individual.
And I think that is important for him to have that humility, it set things up for him to mess up again in the second Avengers and try to set it right.
