"And you've pissed off all of them."
"That was the plan."
Tony owns mirrors, plenty of them. Egotist, remember?
So he recognizes that look, mind moving fast enough to reverse gravity, enough that you don't know down from up yourself. Tap-dancing on a wrecking ball, building fucking grenades on thin ice. Fast enough - maybe then it won't all go to hell, but when it does it will be your hell, and there is a difference.
If you're thinking thirteen things at once, who's to say what you really feel, even you?
So yeah, Tony knows that look, but that doesn't mean he trusts it.
