The fiesta has commenced, and almost everyone back at the office is wearing a sombrero. As Jim and Pam marvel jovially over the hole that Andy put in the half-inch drywall, Karen can't help noticing. Again. Oscar is telling Angela that he's enjoying the fiesta more than he expected, but he's already lost her, because she just saw Michael return with Dwight, the latter of whom is rocking a Battlestar Galactica sweatshirt. Everyone applauds Dwight's return, and Angela is the first to shake his hand. "You did this for me?" Dwight asks in wonder, looking around and totally missing the "WELCOME BACK OSCAR" banner. "Guilty," says Michael.
Karen comes and finds Jim in the conference room and cuts right to the chase: "Do you still have feelings for her?" After an ambushed pause, Jim just nods and says, "Yes." Karen gets up and leaves. Well, okay then. Should have played with him when you had the chance, girlfriend.
It's piñata time. Oscar gets denied, and the broom gets handed to Dwight instead. He declines the proffered blindfold and beats that piñata to death. Michael boasts about how awesome he is for admitting his mistake, and says that he learned something: "I don't want somebody sucking up to because they think I'm going to help their career. I want them sucking up to me because they genuinely love me." Dwight, by the way, is rampaging through the office and absolutely destroying every piñata in his path. We mercifully cut away before he reaches the one that takes him down.
Episode tag: Andy drives along, saying that he's off to management training. "Anger management, technically," he clarifies. "But still, management material." He tells us it's supposed to take ten weeks, and explains how he plans to finish in five. You may recall the plan from "The Merger." And then he meets the moderator and gets right to work.
