(S03E03) It might be a Saturday, but there was work to be done at Sterling Cooper. At the Draper house, Gene was discovering that Sally could be both an ally and an adversary, and is certainly an interesting child. Was Betty like Sally as a child, you have to wonder? Meanwhile, Roger and Jane hosted a garden party on derby day which was a reason for some of the staff to rub elbows.

But not all. Peggy, Smitty and Paul were stuck working on Bacardi at the office, but that wasn't a reason not to party. Peggy's new secretary, Olive, seems to want to be a surrogate mother to Peggy. She worries over her, much to Peggy's surprise. More on that later.

Jane was a source of irritation for Joan when she appeared at the office, and if looks could kill, Joan had her slayed. You could just tell it was one of those, "It could have been me moments" for Joan.

Couple that with Joan's dinner party for Greg's doctor friends, and you can see her straining from the choice she's made. To add insult to injury, Joan finds out that Greg's not the super doctor she hoped he was, and then he puts Joan on display, having her play the accordion and sing "C'est Magnifique." Poor Joan.

Out at the garden party, it was even worse. The soiree wasn't just old fashioned, it was positively nostalgic, especially when Roger performed in blackface to sing "My Old Kentucky Home" and Pete and Trudy did an elaborately choreographed Charleston. Of the latter, you couldn't miss Pete's efforts to impress the higher-ups. He can brown-nose and dance at the same time.

The party was oddly amusing to Betty, who looked radiant even in pregnancy clothes. A strange man approached her and asked to touch her belly. It was a reminder of last season when Betty seemed to seek out the attention of strange men, only now what was her motivation? Don has been remarkably attentive to her, at least when he's in New York.

Don disliked much of the party and befriended a guy at the bar, Connie, who was reminiscent of Gene -- only with his faculties. As Don proceeded to fix them drinks, Don revealed another dark chapter from his past, parking cars at a country club and pissing in the trunks of the richie-riches who didn't let him use the toilet.

While stuck doing the Bacardi work, the resentful Paul -- who wanted to be at the garden party and still chafes at being part of the establishment -- called his old Princeton pal, Jeffrey. The guy was a drug dealer with a satchel full of dope, pills, etc. They wanted grass, and in her typically defiant Peggy Olson way, she tried marijuana, too.

When Olive (who wouldn't leave Peggy alone) disapproved, a lucid -- and high -- Peggy let her know that Miss Olson doesn't need a mother. Like a young Bette Davis, Peggy is coming into her own. She is completely in control even when she's high as a kite, or fooling around with a younger man like last week's show.

The incident with Gene and Sally and the $5 bill seemed less about the money and more about power. Once Sally returned the money, in an oblique way so as not to have to confess to her crime, Gene was ready to resume their relationship. He gave her the book and she read to him again. He didn't need to reprimand her; he just needed her to do what he wanted. Sally could understand that, perhaps because she's truly Don and Betty's child. (By the way, will Bobby ever speak?)

Finally, when Jane made a drunken scene and embarrassed Betty at the party, it was the impetus for Roger and Don to joust. Roger believed Don was jealous of his happiness. Don's reply, "No one thinks you're happy. They think you're foolish," belied the truth.

Later, Don was indeed envious of Roger and Jane dancing alone, so much so that he sought out Betty and kissed his wife. Don needed to grab whatever happiness he could get.
