We start out with Don Draper getting a haircut, a man in the quintessential little-boy role in the barber shop, except he's a grown-up, so this is business, and in comes a rival ad agency guy who tells Don that Jaguar is "a big win" for his "little agency." Shots fired. The balloon of Don's happiness over the Jaguar win thus punctured, he's suddenly more like the Don we used to know, fiery and spouting off-the-cuff ad wisdom and ready to take no prisoners. Meanwhile, Lane is starting off with a good day. Due to his great "fiscal track record," he's being offered a role as head of the 4A's Fiscal Control Committee. He's told, of SCDP, "You keep that place afloat." It's much-needed praise in Lane's drab, sad life, yet too soon everything changes drastically.
After a possible new fee structure is proposed by one of the clients and investigated by Bert Cooper, Cooper comes into Don's office showing him the cancelled check he's found, the one that Don ostensibly signed. Bert blames Don, telling him, "You can’t keep being the good little boy while the grownups run the business.” (Boy-man theme again here!) Don keeps quiet to Bert, though he knows Lane is behind this, and calls him into his office to confront him and finally to demand his resignation. Lane protests, saying he's never been compensated for what he's done for the company, that he can't go back to England like this, that he is deeply apologetic. Don says, simply, "I can't trust you." He gives Lane the weekend to figure out an elegant exit.
But Don is not Lane—their characters are fundamentally different—and doesn't and perhaps can't expect what happens next to happen. Don, the survivor, the guy who does what needs to be done, tells Lane, who says he's "lightheaded": "That's relief. I've started over a lot. This is the worst part." In Lane's head, though, there is no starting over, and that's not relief. He leaves Don's office and moves through the agency, a weird look on his face, offending Joan in a brief encounter, then going into his large-windowed office where he stares outside at the snow. It's obvious this will not end well.
Don, however, is all fired up about the business, heading into Roger's office to say he's tired of "this piddly shit, living this delusion that we're going somewhere when we can't even give Christmas bonuses. I don't want Jaguar, I want Chevy," he says. Roger reminds him of his old love of the fight, saying, "You used to love no. No used to make you hard." Don tells Roger to get a meeting with Ed Baxter of Dow Chemicals, Ken Cosgrove's father in law.
In the 'burbs, Betty and Henry and the unhappy fam are off for a ski trip, but Sally does not want to go, not in the slightest. A typical mother-daughter fight ensues, in which Sally basically wins: Betty will let her go to Megan and Don's instead, though she calls Don to ask, "I wanted to know if you'd have any problem with me strangling Sally." Don has to work over the weekend on his pitch to Ed Baxter, their meeting scheduled for Monday, and Megan has auditions—neither of them are thrilled with the unexpected visit, but Megan is particularly peeved, mostly because Don hasn't told her anything before Sally shows up. She confronts Don about it, but Don has bigger issues to contend with, the firing of Lane Price for one. (I do like the mini-work-equality moment in which Don says he has a lot of work to do as an excuse for not eating dinner, and Megan tells him, "So do I"—"You're going to have dinner with your daughter.")
