It was interesting to see what Elisabeth Moss and Christina Hendricks had to say about how their storylines played out in "The Summer Man" as they had very different perspectives than I did on it.
They actresses believe Peggy was proven to have made the wrong move in firing Joey, which they said established Joan as "just" a powerless secretary and Peggy as a "humorless bitch." I, however, think Peggy was seizing power and respect, as Don advised her to do, and showed that the boorishness has consequences. She also showed that she could directly wield power, not just indirectly manipulate people to get what she wants like Joan was trying to do, but failed.
While watching the AMC video recap of the episode, I also noticed for the first time that Don's gift to Gene was a big stuffed elephant. He brought an elephant into the room. Into his former house (is it still the one that the Francis family was supposed to have already vacated according to the divorce decree?) Hmm.
