I'm very disappointed that Pepper Potts would always allow herself to be pushed around by Tony Stark, even though she is clearly an intelligent and capable woman. She degraded herself to being a slave that only does whatever her master (Tony) wants her to do. She rejects business offers because "Tony wouldn't like it." Not because of her own will.

I hope that in future movies, Pepper allows herself to be free of Tony's influence, and to make decisions that don't serve Tony's desires or wellbeing, but her own wants. She should also have a breaking point, where she questions Tony's ideology, and become enemies with Tony. This woman has potential.
