The newly merged creative team brainstorms how they will market margarine, for Fleischmann's. Don, who is trysting with Sylvia, shows up late, as the meeting wraps, and Ted Chaough chastises him. As a peace offering, Don shares drinks with Ted, but the latter ends up visibly drunk, earning Don Peggy's ire. Don, playing a dominant sex role, sequesters Sylvia in a hotel room, keeps her in the dark about when he'll return, and has delivered to her a red spaghetti strapped dress from Saks Fifth Avenue. He takes the book she is reading with him to read on his flight to Buffalo. After a dream wherein Don dies in a plane crash, and Sylvia attends his funeral and must comfort Megan, Sylvia ends her and Don's affair. Joan falls ill, and Bob Benson discreetly escorts her to the hospital and secures expedited treatment. Roger fires Benson's supervisor, Burt Peterson (for a second time), but Joan saves Benson's job. Robert F. Kennedy is assassinated on the wedding day of Roger Sterling's daughter, Margaret.
