Tony: "I didn't know if you were coming home or if you were having drinks with Aldrich Killian.
Pepper: "You're spying on me."
Tony: "Hey, I admit it. My fault. Sorry. I'm a piping hot mess. Nothing's been the same since New York."
Pepper: "Really? I didn't notice that at all."
Tony: "You experience things and then they're over, and you still can't explain them. Gods, aliens, other dimensions. I'm just a man in a can. I love you. But, honey...I can't sleep. You go to bed, I come down here. I do what I know. I tinker. Threat is imminent. And I have to protect the one thing that I can't live without. That's you."
