Pete's on the train home when Howard joins him and Pete acts like someone who didn't just bang Howard's wife as he jovially says he didn't expect to see him. Howard tells him the evening is going to be some requisite time with the wife and even over the train noise, you can practically hear the gears in Pete's head grinding before he tells Howard that he checked with the office and it turns out Howard was right about the policy. He lets out some line by continuing that he let the company set him up with a broker and Howard goes straight for the fishhook as he's like, wait, what about me, I could come by your place after dinner. Pete, with a face to make Machiavelli jealous, says that actually, their baby's been sick, but he could join Howard for dinner. Howard's down with that, adding that Beth's a great cook and Pete's response of "Is she?" is sublime.
Joan, dressed to leave for the day, tells Peggy in the break room that she missed Megan's lunch, noting that Peggy probably has some extra work given the circumstances. Peggy replies that she just wanted to do her own farewell with Megan, but Joan's in Gossip Mode, saying that she didn't see it coming. "I thought she would fail here." Peggy tells her she worries that she scared Megan away by being too hard on her, but Joan, probably thinking about whoever's going to be getting her nails into her own husband, says that second wives have a playbook. "She's going to be a failing actress with a rich husband." Peggy demurs, saying she thinks Megan's one of those girls who's good at everything and Joan sniffs that in that case, Peggy had every right to be hard on her. Joan goes on with a bit of history about how Betty was a model and he met her doing a print ad: "That's the kind of girl Don marries." It's a little unkind, especially since Megan has proved to be something of a pleasant surprise, but given how Don threw Faye over for Megan, the comment has its place. Of course, Joan's perspective on being a career girl is something that's changed rather a lot over the years, but I'm always happy to see her and Peggy bond.
