House is hanging out at a heretofore unseen park when Wilson walks up and asks him why he's there instead of at work. Why are you, Wilson? Don't you have a cancer diagnosis to screw up? House says that he's enjoying not being at PPTH, and people-watching. Wilson doubts this, since House hates people and therefore would not want to look at them. House says that he'll be staying at the park as long as possible, since it's the last place Cuddy will look for him. At a certain point, isn't sitting in a park in the middle of winter doing nothing worse than actually doing your job?
Since she no longer has a real patient, Cameron goes back to Clinic duty like an idiot. Her patient is a sad old man who hands her some papers that doctors "at the other hospital" gave him. Ooooh, snap! Looks like PPTH just done stole one of St. Sebastian's patients! Cameron reads the papers and sad music plays. Uh-oh. The guy has inoperable cancerous tumor in his lung. Oh, well, he can just take one of that cockroach guy's lungs, then. It's not like he's using them. I'm sure he won't mind, and if he does, House can just shoot him up with something. Old Guy asks if he can sleep at PPTH tonight: "It's cold outside." No, it isn't! We just saw a guy jogging in shorts! House was sitting out there all day with nary a hat on! Anyway, Cameron walks out of the exam room and heads for the chapel to get married to the guy. But Cuddy spots Cameron and asks why Cameron's doing Clinic duty when House has a patient. "He doesn't," Cameron tattles. Aw, Cameron! Geez. She's so cool sometimes, and then she'll come across some dying person and get lame again. It's like terminal cancer is her kryptonite.
House is either frozen to death or napping on a park picnic table when Cuddy comes up and says she knows all about his shirking activities. House is pissed that Cameron told on him, but Cuddy says, "She got punished -- she's stuck with another dying patient." Well, if he wasn't dying before, he will be now that Cameron's his doctor. House pops some pills, and Cuddy is outraged. She stupidly believed that House was off drugs after rehab. She only lied on the stand because she thought House was getting clean. House says that if she's going to hold jail over him every time she wants him to do his job, he'd rather be in jail. "You owe me," Cuddy tells him. And the guy who paralyzed a patient's lungs for no reason suddenly develops a sense of honor.
