Dark Shadows (Mad Men)

Betty is making steady progress in her new Weight Watchers program as Thanksgiving approaches. When she visits the Draper home, however, she accidentally and covertly sees the youthful Megan getting dressed. Later, while helping Sally on a family tree project, Betty finds a love note Don had written to Megan. The note reawakens feelings of bitterness and discontent, and Betty passive-aggressively tells Sally to include Don's first wife (Anna Draper) on the family tree. Sally is taken aback, as she was unaware of her father's secret wife. When Sally questions Betty about Anna, Betty snippily tells her to ask Megan.

While staying with Megan and Don, Sally scolds Megan for lying to her. Later that night, Megan tells Don about Sally's knowledge of the late Anna Draper. Don becomes furious at Betty, but Megan tells him to let it go—Betty wants to ruin the marriage and Sally's relationships with Don and Megan from afar. Sally overhears this conversation, and to get back at her mother, she acts as if the revelation meant nothing.

Don becomes competitive with Ginsberg on the Sno Ball account after covertly looking through Ginsberg's private work, which shows many ideas that Don realises are better than his own. The creatives agree to pitch both Don's and Ginsberg's ideas to the Sno Ball executives. When it comes time to pitch the two ideas at the Sno Ball office, Don commits an act of sabotage by leaving Ginsberg's idea in the taxi cab. After Don's idea wins the account, Ginsberg confronts Don in the elevator and tells Don that he feels sorry for him. Don replies that he doesn't think about Ginsberg at all. Don leaves the elevator and a frown emerges over his face, revealing that he is, in fact, afraid of Ginsberg's youthful talent compared to his own creative decline.

Bert enlists Roger to dine with the Manischewitz executives and tells him to bring his wife, Jane Siegel. When Roger protests that Jane is now his ex-wife, Bert feigns surprise. Roger agrees to Jane's request that he buy her a new apartment, free of old memories, in exchange for her help wooing the client. The client dinner goes well, and the client's son (who is the decision maker in the client's firm) is smitten with Jane. Afterward, Jane and Roger have sex in Jane's new apartment. Jane wakes up the next day, despondent over what she perceives as Roger's "poisoning" of the new apartment by creating new memories there associated with their love.

Megan and Don prepare their Thanksgiving meal, as a toxic cloud of smog hangs over New York City. At the Francis household dinner, Betty gives thanks for having "everything I want".
