Adams thinks it's ridiculous to look for an infection when they could be treating the patient for Gad. Park says that it can't be Gad because the patient would be having seizures. Adams says the infection doesn't show up in his blood, but Park thinks it's just a matter of time. Chase is getting annoyed by them. Foreman sticks his head in to call Taub an ass. He blames Taub for him ever getting the idea to go on a date. He tells Taub to stay out of his business, but Taub thinks he's blaming the wrong guy. Foreman leaves and Chase calls Taub an idiot.

BEEP BEEP BEEP! The patient is anaphylaxing, which I did not realize was a word. It's time for a tracheotomy, and it's being done with a scalpel, not a pen. That's a nice change! Normally on television, tracheotomies are done with random junk. Like that one House did in prison where he used a shiv. But it doesn't work because the trachea is blocked below the incision point. Taub tries Racemic Epinephrine. The nurse says they've already tried that, but Taub says they're trying it again.

House is back. The patient is barely breathing Adams is glad that the tracheal edema can't be from something they did. House thinks he might still be getting poisoned. But by whom? Park suggests squamous cell carcinoma in his epithelium, which wouldn't show up in the chest X-ray, and Chase admits that it's possible. I'd like to take a moment to enjoy the word "squamous" which I always thought was something H.P. Lovecraft made up. But it wouldn't cause hallucinations. So she tacks on paraneoplastic syndrome. House says to get a biopsy. He's not signing on 100 percent, but the biopsy is the plan.

House goes into his office and Wilson smugly shows him the gun he found in his closet. He cleverly pretended to stop looking. House denies that it's a gun and also denies that the bullet is a bullet. He says that it's all a prop from a magic act. The barrel is plugged, so it's not a gun! He puts the bullet into the chamber and dares Wilson to pull the trigger. He insists that it's a blank. Wilson will not. House offers to shoot Wilson, and Wilson is also not happy. House again pokes a pencil into the barrel to show that it's plugged, so it's not a gun, so Wilson hasn't proved he's got a gun. Wilson says that House wins and leaves, grumbling. Then House drops the pencil the rest of the way into the barrel and happily drops the bullet he palmed. Then he looks thoughtful and contemplates the pencil.
