1. Betty (January Jones) did not get mad at Sally (Kiernan Shipka) for asking to eat her dinner with the adults. But Betty hasn't outgrown her childish ways just yet—she's decided to move the family out of the Draper house just to punish Sally for hanging out with Glen.
3. Don took took out a full-page anti-tobacco ad in the New York Times—and also took the fate of Sterling Cooper Draper Pryce into his own hands.
4. Senator Robert Kennedy called Don’s line directly. Uh, WHAT?
5. Sike! PPO's Ted Chaough (Kevin Rahm) was just messing with Don. (That accent wasn’t so great anyway.) But seriously, how could would it have been for Sterling Cooper Draper Pryce to work on that political campaign?
6. A bunch of people got laid off—except for the important ones, of course. [Side note: Did anyone else notice the parallels from the end of last season? Season 3’s triumphant finale was entitled, “Shut the Door. Have a Seat.” But in last night’s episode, Peggy (Elisabeth Moss) asked nervously, “Should I shut the door? Should I sit down?”]
7. Sterling Cooper Draper Pryce got a call from the American Cancer Society. Will all the smoking finally cease?
Which moments from last night’s episode made your jaw drop? And what do you think will happen in the season finale?
