Chase wheels Clancy into the MRI of DOOOM. Foreman and Cameron talk about their boss in the booth while checking out Clancy's insides on the computer screen and finding various alien DNA deposits, thanks to that instantly-created antibody. Foreman needles Cameron about House's condition; before, she was saying that House being wrong about his last case threw him and made his leg pain come back, but now she's denying it. And Foreman knows Cameron well enough to know that she wouldn't change her mind unless she knew something. He wants to know what it was. Cameron tells him about Wilson and Cuddy's little humility lesson. Foreman will do absolutely nothing with this information.
While the surgeons work on Clancy, Chase tells his parents that Clancy should bejust fine after all those alien DNA cells have been removed. In fact, he'll be even better, as some of them were in Clancy's retinas and causing him to need glasses. Now he won't.
Wilson invites House out for a run. He even gives him some Vicodin as a motivator, which House rejects. Wilson would rather dope House up on Vicodin than have to admit that he was wrong to lie to House. Ugh. Wilson accuses him of being in denial that his ketamine treatment is wearing off and says the sore leg could just be a regular old sore muscle. House says that it's his leg and he knows what's going on with it better than anyone. "You're not always right, House. You've proven that lately," Wilson says. Oh, Wilson, you dick. You nasty little troll. Unforgivable!
Wilson's insults do have the desired effect, as House is next seen running on a treadmill in the rehab room. He stops with a cry of pain and then searches through his gym bag for some precious, precious Vicodin. Uh oh.
Meanwhile, over in Clancy's bedroom, aliens are sucking the boy out through the window.
Over in reality, Clancy is having a seizure. Chase tends to him, while Clancy's dad yells at him in panic and desperation: "I thought you got it all!" "Yeah, yell at me. That'll fix your kid," Chase mutters. Maybe save those comments for your inner monologue, okay, Chase? Mouthing off at your patient's loved ones isn't going to help him either.
After the commercial, Chase has apparently gotten Clancy's seizure under control and the Cottages meet in House's office to figure out what's still wrong with their patient. Foreman thinks that Clancy has a neurological problem after all and House was wrong when he said there wasn't one, but Chase defends House, saying that the brain scan was totally clean. House tells them to shoot the kid up with those antibodies again, this time using an IV and being sure to penetrate the blood-brain barrier.
