S7E10 · The Forecast

Complete story — includes the ending

In May 1970, Don sells his apartment. At work, Mathis botches a pitch and, after following Don's advice to use humor, performs disastrously; he lashes out at Don, claiming he succeeds only because of his looks, prompting Don to fire him. In Los Angeles, Lou—now West Coast Creative Director—focuses more on pitching his cartoon than agency business. Joan travels west to help interview candidates for Pete's former role as Head of West Coast Accounts and begins an affair with a wealthy retiree, Richard; he initially ends things upon learning she has a child but later reconciles. As Sally prepares for a 12-day school trip, Glen visits and reveals he is deploying to Vietnam; though he first cites patriotic motives, he later admits to Betty he flunked out of college. He attempts to kiss Betty, who gently refuses him. When Sally later believes she sees Don flirting with her friend, she grows further disillusioned with both parents. Don challenges Sally to be more than just a pretty face in life.
