A couple make out and remove assorted pieces of clothing until they're disturbed by a knock at the door of their hotel room. It's Tom. "Tom -- your husband?" the guy asks the woman he's currently on top of. She throws a hotel robe on and answers the door. There's Tom, who apologizes for intruding on his wife's mid-afternoon romp but there's something she needs to fill out by tomorrow for their daughter. The woman, Julia, grabs the forms and looks for a pen. Tom invites himself in and gives the other guy and his silly ponytail an awkward "hey." Husband and boyfriend shake hands, Julia signs the papers, and Tom gives her a kiss and a "see you later, honey!" before heading out. Well, that was weird. "So ... seems like a nice guy," boyfriend Damian says. Yeah, a little too nice. Julia nods, then keels over with severe stomach pain. Damian is just a pretty boy with a ponytail and thus helpless. "Get Tom!" Julia asks.
It's morning at the Wilson/House apartment, and Sam spent the night again, since she and Wilson are apparently gluttons for punishment and/or the show doesn't want to pay for a Sam's apartment set. Wilson is sitting down to a nice bowl of Colo's Colios, but he'd prefer a stack of French toast from Mickey's, which has been referred to before as his favorite breakfast spot. Nice continuity! Sam finds Mickey's to be gross and heart-attack-inducing and has to go back to her real apartment and change clothes for work, which has something to do with CT scans. Wilson invites her to keep some clothes at his apartment since she's pretty much there every day, at which point House enters and ruins the moment by saying that Wilson just wants to wear Sam's clothes. Like he can't just head down to the nearest Forever 21 and buy his own lady clothes. Please. Sam decides to take off, puts the milk in the fridge door shelf (THIS WILL BE IMPORTANT IN ABOUT THREE SECONDS), and leaves. As soon as she's gone, House points out that she left the milk in the door, and that signifies the end of Wilson's relationship. Wilson doesn't see how, but House says he knows that Wilson hates it when people put milk in the door shelf (how do you even know that about someone you're just friends with? Even if you live together? I have no idea how my roommate feels about fridge milk placement. I would like to know why she always buys half a gallon of 1% and half a gallon of skim, though), but he didn't say anything to Sam when she did it because he doesn't feel like he can be honest with her. Instead, he'll just get all resentful until it explodes into a huge relationship-ending fight, just like how their marriage apparently ended. As soon as House is out of the room, Wilson takes the milk out of the fridge door and puts it on the shelf.
