Jim and Pam leave through the front door together, agreeing they'll see each other tomorrow. He starts to put in headphones, and she asks for one of them, so he wears one earpiece and she wears the other, and they listen. It's so interesting, because this show almost never has any music that appears in any way other than an ironic one, so seeing people swaying silently to music you can't hear is surprisingly powerful.
Michael and Jan bid Christian farewell in the parking lot, and when he's gone, they happily squeal to each other about getting the account. "Come here!" he hollers, and they happily hug. He pecks her on the lips, and then...freeze! Uh-oh! Yeah. Then they're making out, for which they look to be equally responsible, and it is terrifying. She pulls away, ordering him into the car. "Where are we going?" he asks, then he says, "Doesn't matter," and he gets in the car as the documentary crew, clearly far away, grabs the critical shot.
The next morning, the camera guy busts into the office, which is dark, to find Dwight sleeping on the couch under a space blanket, apparently having waited up for Michael. We get to watch Dwight in his undershirt and blue briefs (zoiks) as he stomps around in a daze, still looking for Michael. Dwight peers out the window and sees Jan getting out of a cab in the DM parking lot. She looks around nervously. She zaps her car with her remote unlock, and she gets in.
Later, Michael arrives at work. In a TH in his office, he giggles while insisting that "nothing happened." He desperately wants to tell, though, and eventually, he does: he took Jan back to her hotel, where they "made out." Suddenly, Dwight stomps in, asking, "Did you do her?" He sounds almost spurned, which is really something. Michael tells Dwight that it's none of his business, in a way that would tell any remotely aware person that something did indeed happen.
