Faye confronts Don for leaving the meeting early, and declines his offer to go out for dinner. Don gets a Christmas letter from Sally expressing her desire for him to be present in their home on Christmas morning. Sally commiserates to Glen about Don's absence in her home; Glen later breaks into the Francis home and vandalizes it, but leaves Sally's room untouched. Peggy's boyfriend, Mark, urges her to have sex with him, but she puts him off. Now 18 months sober, Freddy Rumsen turns up at SCDP and provides the client Pond's Cold Cream in exchange for a job. After seeking advice from Freddy, Peggy decides to have sex with Mark, who believes that he has taken her virginity. Roger mistakenly invites Lee Garner, Jr. to the firm's Christmas party, forcing Lane to expand the party's budget beyond their means. Don has a drunken one-night stand with his secretary, Allison, but later hints that they are to pretend the encounter never happened, leaving her rejected and hurt.
