Tony Stark: You stood by my side all these years while I reaped the benefits of destruction. Now that I'm trying to protect the people I've put in harm's way, you're going to walk out?
Pepper Potts: You're going to kill yourself, Tony. I'm not going to be a part of it.
Tony Stark: I shouldn't be alive... unless it was for a reason. I'm not crazy, Pepper. I just finally know what I have to do. And I know in my heart that it's right.
