Pryce sincerely tells Joan how happy he is to see her, but Joan, having heard nothing to assure her that she still has a place at SCDP, looks loaded for bear. She does consent to take a seat, but Pryce, if you know what's good for you I'd keep your distance.
Peggy wheels Kevin into the open work area and asks Megan what "they" are supposed to with him, but Megan and the dark cloud over her head are unhelpful, and then the show can resist no longer as Pete enters and gives a hilariously bewildered look Peggy's way. After explaining that this is not their child but Joan's, she asks him to take Kevin back to his mother, and after making an obligatory sexist comment, he agrees.
Peggy and Megan then discuss Joan's appearance, and when Peggy opines that she didn't look great right when she was about to pop, Megan wonders why she didn't tell her that. "You seem to say whatever's on your mind." Oh shit. Peggy asks if something's wrong, but Megan says no before handing over some Vicks coupons. "I know you thought you were the only one working this weekend." Oh shit! Peggy, as you might expect, tries to apologize but doesn't quite stick the landing, setting Megan off about how they're all so cynical, and they smirk instead of smiling, and "who wouldn't want a surprise party?" Of course, she's just blurted this to the very person that warned her about Don's probable reaction, but Peggy is genuinely sympathetic instead of superior; nevertheless, Megan stands and says she's not feeling well, and asks if she's allowed to go home. She looks rather heartbreakingly hurt, and Peggy makes a far better second try at an apology, which Megan maybe sort of accepts before heading off. Peggy kind of looks like she'd go home too, if, you know, she ever did.
