And so, they paint. While Foreman and Chase wait for the cancer cells to light up like a grim reaper Christmas tree, Foreman talks to Chase about Cameron, sincerely saying he's sorry that it didn't work out. Or did it? Because Cameron is standing just outside the OR looking like she has something to say. Chase abandons his patient and goes to her. "I don't wanna be homeless!" she says. This makes no sense to Chase, so she clarifies that she wants to marry him and she's ready to destroy the sperm to do it. Chase is thrilled, but he can't hug Cameron since then he'll have to re-scrub to go back to the OR. Just when he's about to do it anyway, Foreman yells that Scott's BP is dropping. And there are no glowing cancer cells to be found.
Wilson finds House on the lobby balcony railing. He asks him if he really wants Cuddy, or is just immersing himself in the challenge to take his mind off of other things. House accuses Wilson of not wanting him and Cuddy to be together because it'll mean less time for them, as if alone time with House is some kind of prize. Wilson says he's happy for House and Cuddy if their relationship is genuine, and says that if House is really serious about Cuddy then he needs to treat this seriously as well, or else one or both of them will get hurt. And then we see why House is even hanging out at the lobby balcony -- to get a front-row seat when Cuddy kicks the pirate stripper he ordered out of the Clinic. She walks him past a couple of PPTH security guards, who let a man dressed in a breakaway pirate costume into PPTH in the first place. They suck. House asks Wilson if Cuddy looks angry. Wilson tells him to stand back before Cuddy sees him. "Oh no," House suddenly says. I'd just like to know why Wilson keeps switching out his ties, but I'm sure that won't be important later.
House runs from one balcony to the other, appearing in the OR balcony to tell Chase and Foreman, who are busily trying to save Scott's life, that the clots aren't cancer at all -- they're coming from Scott's heart. The scans showed that his heart was fine, but that's only because they weren't looking at the right time -- it's an intermittent arrhythmia, and can only be seen when it's happening, which House is guessing, based on Scott's vital signs, is right now. He tells them to do some kind of echo to confirm it. Fortunately, they have the necessary equipment ready to go in the OR and are able to see it before Scott dies. House says they have to fix the heart, then find out what damaged it in the first place.
