I enjoyed the newly thin and once again scrumptious Betty, although her husband seems to have a hard time dealing with every man who sees her circling her like a fruit fly.
It's clear, though, that Betty is loving her newly regained sex appeal. It will be interesting to see what comes of her encore roll in the hay with Don. I love Megan. She is a sweet, decent, girl who is playing a bad hand. She deserves a lot better than the likes of Don Draper.
Meanspirited though it may have been, I laughed when Peggy accidentally stabbed Abe with a home made spear and he broke up with her because she was in advertising and, therefore, "the enemy." I think the break up may have been the luckiest break of Peggy's life. The self-righteous, would be revolutionary, Abe, was not ready for prime time. When Peggy agreed to move to a horribly dangerous neighborhood with Abe in the name of multiculturalism, or something, I thought she had lost her mind. Anyway, it looks as if she can get out from under that now, and it's a good thing. On a sadder note, Chaough dumped her like a hot potato when he learned that she had broken up with Abe. This was far different from his hints to her that he loved her when she was still in a long term relationship with someone else.
Peggy had a much better moment earlier in the show. After Don criticized Peggy's failure to support his position in a debate with Chaough about advertising strategy, she told Don that getting along with Chaough was his job and her's wasn't to mediate their disputes. She pointed out that Don and Chaough were a lot alike. Peggy proved again that she understands Don. Given how Chaough treated her when he learned that she was again unattached, it appears she was right about Chaough too.
Don proved again that he's the same old Don. Sylvia no longer being available, he philandered with his once again hot ex wife instead. Don is a rat but he is certainly a fascinating rat.
