Kevin starts out with a discussion of his famous chili.
As he spills the beans about the secret ingredient ("undercooked onions"), he literally spills the beans, all over the floor, next to Jim's desk.
He tries vain to save the food, shoveling it back in a giant pot using clipboards, but ends up slipping and sliding all over the place.
Michael makes a triumphant return, bit it turns quickly into confusion and frustration by his reunited staff. They aren't pleased that Pam and Ryan have been promoted to sales AND get to keep their clients they stole from Dunder-Mifflin while with The Michael Scott Paper Company.
Michael tells them to suck it up and deal, and then switches the subject to the return of Casual Fridays.
Dwight orders a secret meeting, using invisible ink (urine) to code a message for the sales team, minus Ryan and Pam.
They all meet in the warehouse, where Dwight says something fishy is going on. Jim says they should just talk to Michael. Dwight demands action.
Jim comes in to warn them about the pending mutiny.
Michael says he's not going to take it. When the crew returns, they lie and say they were out to lunch. Michael calls their bluff and destroys their packed lunches.
Casual Friday, meanwhile, takes a turn for the worse. Toby tells Meredith her minidress is too, well... slutty. He tells her to pull it down. She does, revealing far more than anyone needs to see.
Jim has been hiding in the lunch room, playing chess with Creed.
The sales feud hasn't ended, though. When Ryan tries to talk to one of Dwight's long-time clients, Dwight freaks. The guy hangs up.
Then the emotions start flowing. Michael says the sales team should get over their hurt feelings about Ryan and Pam getting clients, but they threaten to quit and start a new paper company.
Michael calls their bluff again, saying if they want to go, great, but if they want to stay, apologize.
Phyllis is near tears. She says Michael screwed them, not corporate, when he left. That gets Michael to realize he was wrong.
He ends up giving Phyllis, Stanley, Dwight and Andy their old clients back.
Now Michael has to let go either Ryan or Pam. He asks Jim for advice, but he is busy playing Scrabble with Creed.
Jim and Michael go through pros and cons of Ryan and Pam.
Michael goes with Pam, and offers Ryan his temp job back, though Ryan isn't thrilled with that. While he's on a roll, Michael fake fires Erin.
Toby, by the way, cancels Casual Friday.
