Before you watch its Season 6 premiere Sunday at 9 p.m. on AMC. Here's a cheat sheet of the fifth season finale, “The Phantom,” to remind you where we left Don, Megan, Pete, Roger, Peggy, Joan, and everyone else.
1) Don has an infected tooth
Lane (Jared Harris) committed suicide in the previous episode after Don (Jon Hamm) found out he'd stolen from the company and forced him to resign. Still shocked and upset, Don is in some pain so deep it's become literal.
2) Pete runs into Beth and her husband on the train
Pete (Vincent Kartheiser) was so miserable in Season 5 that a considerable number of viewers were convinced he was going to kill himself. In the finale, he is forced to revisit his obsession with his neighbor and fling, Beth (Alexis Bledel, now Kartheiser's real-life fiancée — squee!).
3) Harry complains to Joan about his office not being big enough...
... while Joan is on her way up to the floor above them to check out potential new office space in which to expand.
4) Don sees his dead half-brother, Adam
Lane hanged himself. Adam, Don's half-brother — or technically, Dick Whitman's half-brother — hanged himself in Season 1. Don's grief and shock over Lane, presumably, and the general theme of death that tinges Mad Men, has conjured visions of Adam.
