Don and Betty: Wow, Betty actually did it! She asks for a divorce so that she can leave Don and marry Henry Francis. This was the only bit of tying up that had nothing to do with work. This year was very personal, focusing on the denizens of Sterling Cooper in their personal lives rather than in the office, so it was a bit surprising when the final episode centered around the creation of a whole new office. Of course, we couldn't forget about Don's disintegrating home life.

When he comes home drunk to confront Betty about Henry, he puts her journey this season into perspective: Betty was building a life raft. Everything she's done this year has been to get away from Don. Starting things with Henry, finding out his past, getting money from her father—it was her escape route. After all his transgressions, divorcing Don wasn't so much a circumstance, but an inevitability. Poor Betty, doesn't she see that she's leaping from one bad situation to the next. Henry Francis—who barely knows you but wants to marry you!!—will probably be just as bad and stifling as Don. Just as Don said, he gave her everything she wanted, and that wasn't enough, she still wasn't happy. Why does she think replicating it with Henry will have some magically different effect?

When Don chooses to insult her, he really knows how to do it. He calls her a bad mother which, duh, and then calls her a whore. There were several prostitute references last night which are that much more meaningful given Don's mother was a hooker. When he needs to show ultimate disdain for Betty, that's the word he goes for. When talking about the sale of Sterling Cooper, Roger says it's like going from "one john's bed to another." Painting the old firm to look like a whore is the surest way to get Don to distance himself from it. Also, Lane Price's assistant "Moneypenny" is really named Mr. Hooker. We don't know how that fits in, but...hmm?

Back to Betty and Don, she takes off for six weeks in Reno so that she can get an easy divorce from Don, because she can't prove that he's been unfaithful. Maybe she should make about three phone calls, because the wronged ladies shouldn't be that hard to dig up to testify against him. Of course bad mother Betty leaves the kids with Carla while she jets off with her new lover to Reno to get divorced/married. This makes us hate Betty.

Also, the scene where they tell the kids about the divorce was super painful to watch. Don tries his best to pitch the kids on the idea of their new life, but they're not buying it. Betty can't do anything but hide behind her hand and try to keep the tears in. Future lesbian Sally storms off, sad that daddy is leaving. Little Bobby pleads for daddy to stay, but he won't. No wonder this kid is going to be snorting lines with a very dapper, emotionally-distant Halston in the VIP lounge of Studio 54—he's working out some serious daddy issues. But when Don hugged his son and earlier when he climbed into bed with Sally, we see that he really cares deeply about his children, despite his cool demeanor. But he barely sees them now that they live in the same house, how much time is he going to spend with them now?
