Iron Man: Armored Adventures2008

Tony Stark:
[in his Iron Man suit, having just saved Pepper from danger] You're gonna be okay now, Pep... per... man... Whoever you are.

Pepper Potts:
Thanks... Tony.

Tony Stark:
Tony! I think you have me confused with someone else.

Pepper Potts:
Relax. I know it's you. I'm not stupid. My dad is a professional investigator, remember? And besides, no one can go to the bathroom as much as Tony Stark does.

Tony Stark:
[opening his mask so she can see his face] How long have you known?

Pepper Potts:
I didn't! Oh, man, but I do now! I can't believe you are really Iron Man! And I can't believe you fell for that. I thought maybe you were, I tried to ask you, but... wow! Ooh, we're flying. This so awesome!

Tony Stark:
You stink, Pepper. I'll take you to Rhodey's house, I'll meet you there. But when all this is over, I'll have to wipe your memory.

Pepper Potts:
Really?

Tony Stark:
No. But I'm thinking about dropping you.
