In a new interview with Jon Hamm (Don Draper) and Elisabeth Moss (Peggy Olson), Vulture asks the pair about what we can expect from the upcoming Mad Men season. We also hear them discuss the great dynamic between the two beloved characters!

On season five teases:

No, I still need both of you. I’m hoping one of you will spoil season five for us. Any surprises?

JH: There are a lot of things where all of us as a cast were like, Whoa, okay. Uh, all right, so this is happening. It’s a world that’s consistently in a state of flux. There are things done that can’t be undone.
Can you be more specific?

EM: There’s something that Matt said, that these characters have to figure out what they want and how to go after it. That summed up my character.

JH: Matt has also said it’s every man for himself—that’s obviously not gender specific. Everybody is acting in their own self-interest, and that creates some pretty good dramatic tension.

On the pair’s on screen chemistry:

Some of the best moments of the series are duets between you two, as in “The Suitcase.” What is it about Don and Peggy?

JH: It’s not a mistake that the show starts on Peggy’s first day at work. In many ways, the story of Mad Men is the story of Peggy Olson: a young, ambitious, talented girl finding her way in this crazy world. I think Don and Peggy have a special relationship. They’re unsatisfied with who they are and are willing to do what it takes to become something else.

EM: People are constantly asking if they’re gonna sleep together. I always get annoyed, because their relationship is more than that. And to keep that going over five years without selling out and having something else happen—that to me is really interesting and rarely done well.

JH: People want to put us in a “Sam and Diane” box, but it’s about their mutual appreciation for the work. That’s where the material strikes its resonant chord, when it’s ostensibly about one thing and then it becomes about so much more. That’s the fun thing about Don and Peggy, and that’s the deeper thing about Mad Men.
