Chatting with TVLine, the show's creator Matthew Weiner teased that Elisabeth Moss, “is going to be on the show next year. I can’t say how much, in what capacity or what [her story] is going to be, but she has not left the show.” But he does understand how people would get that idea. “When people leave Sterling Cooper, sometimes it is the end for [the character],” Weiner said. “But I will spoil that one tiny piece of anticipation and tell people that Elisabeth will be showing up to work.”
Of course, just how Peggy will be incorporated will be anyone's guess, and if anything, Weiner has proven to be as unpredictable as he is secretive about the fate of any of the characters on the show. Do you think Peggy needs to return? If so, how do you think she'll be looped back into the story? At any rate, Peggy is a pretty rich and interesting character (one of the show's best), and whatever Weiner has planned, we're eager to see where she goes next.
