What is the title of the episode in which Don fires Jaguar?

The title of the Mad Men episode centered on Don and the Jaguar account is “The Other Woman.”

It is the 11th episode of season 5 and the 63rd episode of the series overall. The episode originally aired on AMC on May 27, 2012, and its story is set in January 1967.

Jaguar becomes the pivotal account when dealer-association head Herb Rennet demands a personal favor involving Joan Holloway. Don rejects the proposal and instead focuses on winning the account with a strong advertising pitch. The agency ultimately lands Jaguar, although Don later realizes that Joan had already made her own sacrifice to secure the deal.

A common mix-up is “The Phantom,” which is the following episode, season 5’s finale. “The Other Woman” is also notable because Peggy Olson leaves Sterling Cooper Draper Pryce for a creative leadership role at rival agency CGC.
