"The Other Woman"
So, this episode was all sorts of amazing! Emmys, just give Christina Hendricks her Emmy now. Seriously. Just do it.
Don's reaction when Peggy told him that she was leaving was absolutely heartbreaking! He did take advantage of her and the fact that he figured she would always be there, but she's his rock. She keeps him in check, or at least tries to, but now she's gone. Way to go, Mad Men, way to break my heart and make me REALLY want to comfort Jon Hamm... I mean, Don.
