The next time it happens the suit isn't on, and Tony's at a press conference.
The woman asks about his usefulness on the Avengers team and he freezes for a moment before deflecting the question with 'No comment' and moving on. Then she continues asking and asking, and asking, and her questions get worse and worse and worse until she finally asks him if he thought the team would be better off without him. Luckily, he doesn't have to answer because suddenly there's thick smoke and he's dizzy and there's a hand under his armpit and one around his mouth and then it all goes dark.
Tony had never before been so grateful for a kidnapping in his entire life.
It's normal because they want him to build weapons and he says no, so they torture him. It's better than the waterboarding, he thinks. But then he gets sick of it so he says yes then builds a bomb because they are dumbasses and hightails it out of there. Then he finds a payphone and calls Pepper who against his will calls the Avengers who pick him up.
It's okay that his back is shredded from the bad end of a whip because anything's better than the waterboarding and it's okay that he's a little shaken up but it's kappened before. What's not okay is that they trust him to do a press conference and that woman is there and she asks, asks, asks, until he's fed up with it and snaps yes.
He doesn't understand why she looks so shocked, because that was the answer she wanted, and then he leaves because he's just so drained.
When he'd out of the limo he ignores everyone but JARVIS and heads down to the workshop to drink himself unconscious, because he is just so done with the mask and just everything.
Because deep down, Tony is done being himself.
