Peggy's preparing for a big Heinz presentation, which is putting stress on her relationship with Abe. Don and Megan bail frivolously (well, it's really his decision), increasing Peggy's anxiety, and when Raymond, the Heinz guy, hems and haws about Peggy's pitch, she gets in his face about how he doesn't know what he wants, leading to her getting fired from the account. Needing an escape, she goes to the movies and gets stoned with a random dude, eventually yanking him right there, and considering it's a wildlife movie, they're watching, you can only imagine what might have happened if the content had been a little racy. Ginzo's dad shows up to the office, and Peggy, upon her return, sees him; later, Ginzo uses a narrative conceit to tell Peggy that he was born in a Nazi camp, and the father she met found him in a Swedish orphanage when he was five. Peggy, much like the audience, is all "Whoa" about that revelation.
From here, the timeline of the episode goes non-linear. In flashback, Roger tries to get Don to take a business trip with him to the flagship Howard Johnson's in Plattsburgh, but Don decides to take Megan instead. Turns out Roger was trying to get out of a dinner party thrown by Jane's therapist (BESS ARMSTRONG, Patty Chase from My So-Called Life), and they all take LSD together. I wouldn't have guessed Roger would be the first regular on the show to drop acid, and I admit I can't imagine what I was thinking. Roger's individual trip doesn't have too much to do with tripping – Jane's is far more believable -- but it's still hilarious and John Slattery sells the crap out of it, and their later conversation is honest and allows them to break up with a minimum of animosity; even though Jane makes an attempt at disavowing the sentiment the morning after, the relationship is dunzo.
Seeing the earlier scene from a different angle, Megan's reluctant to leave before the Heinz presentation, and even though Don of course gets his way, Megan stays preoccupied with wondering how it went, and eventually expresses resentment toward Don for not allowing her to value her work. This leads to an ugly fight over orange sherbet which culminates in him leaving her at a Howard Johnson's, and given that he fell in love with her over a milkshake at a similar type of dining establishment, this seems like a pretty plausible and symmetrical end to this marriage. However, despite Megan pushing buttons of Don's he never knew he had, he returns, only to find Megan has disappeared without a word; this leads to a phone call to Peggy (which we saw earlier), which leaves him sweaty and frantic. Eventually, he returns to New York to find Megan already back at the apartment; he kicks in the door and chases her around the place, and it's as sad and unsexy as it is passionate; even though they give each other a fond smile at work later, you're not in the game if you haven't made a guess as to how many episodes are left for this marriage.
And the dissolution of same might be for the best, as when Don comes in, Bertram informs him he's been on "love leave," and as such hasn't been doing nearly enough at work. Roger then sticks his head in and opines that it's going to be a beautiful day, and surely this is going to drive Bertram's point home. Because surely even lovesick Don knows who's the one to trust between Roger and Bertram, wouldn't you think?
