The professional became very personal last night, as Sterling Cooper dissolves and Don has to account for all his past behavior in order to survive. As we all wonder what the future holds, the past has finally been sorted.

The season finale (directed by show creator Matthew Weiner himself) was all about Don's relationships and how he rectifies them in order to move on creating his own advertising agency. Usually happy to be the lone gunman, Don has to rally the troops in order to stake out on his own, which means checking his ego, doing some apologizing, and letting some of the people in his life know just how he really thinks about them. And Joan came back! And Trudy wore a killer hat. All was right with the world as it—and Don—strikes out in a new direction.

Don and Connie: As he has been all season, Hilton is a stand in for Don's father, who also got some face time this episode. We learn from Hilton that Sterling Cooper has been sold to a larger agency, one that Don—or anyone else for that matter—doesn't want to work for. Because of that, Hilton drops Don, which leaves him in the lurch because he had to sign a three-year contract to secure the Hilton deal in the first place.

But what he's really upset about is that he doesn't have his independence. He is energized by Connie's final question: is he going to be a whiner or is he going to be a winner? And with the promise that they'll do business again in the future, Connie gives Don the final push to try to take his future into his own hands.

This leads to the flashbacks concerning Don's father, who we learn wasn't happy with the price his crops were going to get in a cooperative, so he struck out on his own to do what was right for him. Instead of selling for cheap, Whitman Sr decides to hold onto his crop and sell it in the winter when it will fetch more money. Though Don tried to shed his past like a snake wriggling out of a dirty skin that was far too tight, he is still his father's son. When things aren't working out for him, he decided that he would rather do the right thing on his own and possibly fail, than succeed as an automaton for The Man.

This is later reinforced when we learn that Don's father was literally killed by caving in. When there isn't much money left, Don's stepmother convinces her very drunk husband that he has to sell his crop. He says he'll go immediately, and Don goes with him to make sure he doesn't literally fall off the wagon. But he doesn't even get on the road, when a spooked horse kicks him in the face and kills him. If he had stood by his principal and held onto his crop, he never would have been out there to be kicked in the first place, and might still be alive—or at least lived a bit longer.

While Don might be the indepence-at-all-costs, up-by-the-bootstraps, fuck-them-all-I-know-what's-right product of his father, he is determined not to be him. He is not bending over to get kicked in the face while McCann fucks him for the rest of his life.

Don and Roger: It was easy for Don to convince Bert Cooper to get on board with his plan of buying the agency (or striking out on their own, as they eventually do) since Cooper would be let go if the agency was sold again. However, it wasn't going to be a cake walk to convince Roger Sterling, who Don has spent the whole season trying to distance himself from.

It would seem that Sterling would much rather sit in his office counting his piles of coins like Scrooge McDuck while kicking back a few drinks and then going home to goose his pretty young wife before passing out in his expensive bed than actually run an ad agency. But he has the money and the accounts to make a new agency work, and it seems like he still has the ambition too. What he really needs is Don to supplicate himself, which he does with great sincerity. Roger hits the nail on the head when he tells Don he's no good at relationships because he doesn't value them. We see that with his home life as well as how things go around the office.

It's great that egotastic Don can be self actualized enough to know he needs Roger to deal with the clients and make them happy, since that's not in his grainy little heart. As we see during their scene at the bar when Roger tells Don that Betty is seeing Henry Francis, Don and Roger work much better when collaborating than they do when competing.

The other brilliant thing that Roger brings with him is St. Joan. As soon as Cooper brought up the fact that no one knows where anything is, we thought, "What a brilliant way to bring back Joan," and the vision of her sauntering in to save the day with her red hair coaxed into tight perfecting and the gold pen swaying seductively between her enormous knockers brought tears to our eyes. Welcome back, kiddo.

Don and Pete: Don has never been the biggest fan of man-child Pete, but both he and Roger know that Pete is the much better account man for the small (at first) firm they're planning than Ken Cosgrove, the upward failing buffoon who seems like he was made for a life in middle management. While Ken might have beat out Pete at Sterling Cooper because he was a yes man who could fit into the corporate culture, he doesn't have the instinct that Pete has to make it in the big time.

Of course, to get him, Don has to put his condescension aside and let Pete know that he will be a valued member of the team. Of course, Pete asks for more than he's worth, but better that than not asking for enough. This is really the best possible outcome for Pete. He was on the outs at SC anyway, and his interviews at other agencies may or may not have panned out, but he will succeed quite nicely at a firm that will value his gifts while overlooking the fact that he is an immature cad deep in his chewy center.

Speaking of great members of the team, Pete would really be nothing without Trudy. She fixes things up all nice when Don and Roger come a-calling, and excuses herself with a plausible story when they get there. When Pete starts to lose the way her call of "Peter, can I speak to you for a minute," sets him back on the right course. She isn't allowed into the conversation, but just knowing that she's listening turns his rudder in the right direction. She never strong arms, she just nudges. And then she brings sandwiches. And wears a cute hat! If Betty is gone for good next season, we're going to need someone to give us Suburban Splendor Barbie realness, and it's going to have to be Trudy.

Pete got over his hurt quickly and signed up, and another easy sell was Lane Price. Unhappy with being unappreciated, shuffled around, and generally maligned by his bosses and liking the life in New York away from the class constraints of his native land, Price was ripe for the crew to pick off. Considering he was integral to their plan to get the ball rolling, it's good he agreed. We look forward to seeing more of his strangely shaped head around the office. But, oh, his poor wife!

Don and Peggy: Don handled the Peggy situation all wrong, at least the first time around. He naturally thought of her first to take with him to the new agency, but he orders her about like he controls her. It's funny that Don has such a great way with seducing women in his private life but he can be so blind to what Peggy needs at work.

This whole season Peggy's storyline was about empowerment. She smoked weed, she slept around with a boy, she got an apartment and a roommate, she put her domineering mother behind her, she even got her secretary to respect her (even though winning over her colleagues was a bit harder). And finally, she realized that she has a promising career in advertising and a sexual being, both thanks to skeevy Duck. So when Don comes at her like she's a blubbering child, she finally stands on her own, letting him know that she has other offers, and that she is not there for him to kick around. Spurned, Don reacts the way he usually does when he doesn't get his way, by being a cocky asshole.

The way he handles her the second time was perfect though. Don uses his best pitching skills to win Peggy over. Don knows that things have changed—not just for him and the firm, but something fundamental in the culture—and that Peggy is necessary to keeping up with that shift. She's smart and creative and, like Don says, a miniature version of himself. She is often depicted as a mini Don, giving up her personal life for work, but this episode she seemed more like a grown up version of Sally. When Don makes his offer for a second time she says, "If I say 'no' you'll never talk to me again," and starts to tear up, betraying that all she really wants from Don is his approval. The scene where Don makes up with Peggy comes right after the scene where Sally storms off when he tells the kids he and Betty are getting divorced. It seems like Don making peace with Peggy, his office daughter, is somehow akin to him making peace with Sally.

Of course, Peggy agrees to join the team (she nearly broke our heart with joy with the tiny wave of excitement she made when storming the office) and her best moment was yet to come. When the newly assembled Mad Men All-Stars are planning to extricate themselves from the office, Roger tells her to go make him some coffee. She is a secretary no more, she is an equal member of the team, and she is strong and secure in her position. "No," she says in an even and forceful tone, which says, "You will never ask me to do that shit again."

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?

Sterling Cooper Draper Price, How May I Help You?: Don Draper's marriage may have dissolved, but his firm has just started. He, Roger, Bert, and Lane have drafted Peggy, Harry Crane, Pete, and St. Joan as their coalition of the willing to steal clients and bust into the art department (yes, we saw that someone placed a curlicue letter F in front of Art Department) to take whatever they can get their hands on.

This wasn't necessarily a cliffhanger, because the decisive action has been taken. We won't be left guessing "Will they leave?" a la "Who shot J.R.?" but we are left with plenty of questions to ponder over the winter (or in the comments section). Here are a few:

Now that Peggy and Pete are working in a tiny office together, are they ever going to come to terms with their past?

What is going to happen to Peggy and Duck? Is that still going on? Is he going to ruin Don's new agency?

Just what the heck is Bert Cooper going to do? There's no room for his armor and he can't take naps anymore. Do they even need him?

Lane Price's wife was unhinged before their stay in the U.S. became indefinite. How soon before she goes completely bonkers?

So, does this mean Betty is gone for good or are we going to get to see her staggering unhappiness with Henry?

How soon before Roger starts doing Joan again?

How soon before Doctor Rapist is killed in Vietnam?

Will they think of something interesting for Harry to do?

And what the heck is going on with Suzanne (nee Missy) Sally's teacher that Don was diddling? Why didn't he just go right back to her when Betty called it quits? Will she be coming back?

How sweet is Don's bachelor pad going to be? Just wait for the Mad Men furniture line at CB2.

If Don isn't married, is he just going to spend all of his time scoring ladies or just most of it?
