Michael drives himself crazy-paranoid over a secret meeting between Jim and Wallace. Thinking Jim's trying to squeeze him out, Michael sabotages him, only to learn that Jim's secret plan was to take over the Scranton branch and have Michael promoted to boss of all northeast sales. To save his friendship with Jim and his hypothetical promotion, Michael tries to take it back. Ultimately, there will be changes again in Scranton: Michael and Jim will be co-managers. Dwight is so horrified he forgets all about his complaint against Darryl for workers' compensation fraud. Meanwhile, Pam spends the day trying to chase down RSVP responses for the Niagara Falls wedding. Come on, Pam, like there's anyone in the entire cast who's going to not show up.
Michael has called Oscar in for a private chat. It seems Michael is a little nervous about an upcoming medical procedure. Oscar, who should know better, acts concerned and sympathetic, until Michael begins asking what to expect. "Is there anything I can do to make it more pleasurable to me or Doctor Schondry? My main concern is, should I have a safe word?" Fortunately, Oscar doesn't need one of those; he can just get up and walk out. Which he does.
David Wallace is at the branch, asking Michael when he should expect that rundown on the Buffalo clients. Once that's squared away in Michael's typically annoying fashion, Wallace invites Jim -- wearing a suit jacket today, so you know big doings are afoot -- into the conference room. Pam is smiling proudly at Jim, but of course Michael's typically weird about being left out. And he's just getting warmed up. Not that he doesn't try to convince us otherwise in a talking-head shot in which he claims that he and Jim and Wallace are the ¡Three Amigos! and sometimes ¡One Amigo! will go to the bathroom while the other ¡Two Amigos! have a secret meeting. Sorry I don't really have a joke to go here other than that typographical gag.
"You and Jim are close, right?" Michael asks Pam after escorting her the three steps from the copier to her desk. "Yeah, I think the pregnancy really brought us together," Pam agrees. But she pleads ignorance about what the meeting might be regarding. Michael literally gets on his knees next to her and threatens that her baby will come out a liar if she's lying to him. Pam doesn't really have anything to say to that other than, "Please don't talk about my breast milk." I know I left out part of the setup, but that line really never doesn't apply.
Darryl is at Toby's desk in an Eagles jersey and shorts, balancing a pair of crutches on his lap, and explaining how he broke his ankle in a ladder accident in the warehouse. Dwight's hovering at the doorway eavesdropping, and when Darryl hobbles away, Dwight leans on Toby to look into it. Eventually the two of them head down to the warehouse to try to reenact the incident without Darryl. Toby admits in a TH that Dwight was correct in pointing out that the ladder doesn't reach the top shelf. Toby's actually kind of enjoying this, as a fan of hard-boiled detective stories. "I'll punch you in the mush, see?" he dorking-heads.
