Anyway, time's up for Hadley to return. Jason lowers his gun at the Kid, but then Nurse NotCarla jumps up and volunteers to be shot instead. And you know she only did that just to prove something to House. Her life is less important than showing House he's wrong. When Jason aims the gun at Nurse NotCarla, though, she's not quite so willing, and begs Jason to give Hadley more time. And then the crisis is averted when Hadley returns. Way to cut it close and get the nurse all upset, Hadley. The nurse is like the only character on this show so far who isn't an asshole. She deserves better!
House readies the syringe, but once again, Jason insists that Hadley take it first. House says that will slow her heart down, and since her heart isn't beating fast like Jason's, that will be bad for her. Hadley immediately rolls up her sleeve. She might want to jog in place and do some cardio first, just to get her heart rate up, maybe? Jason says Hadley now has to take everything he does, to make sure the drug won't kill him and also that it won't react with another drug he's taken. Also so that we, the audience, will worry if she'll be okay. Rest assured, I will not worry. Hadley shoots herself up before House can argue. Then she collapses. But she doesn't die. Instead, House reports that "the martyr's heart is beating dangerously slow." Hey, don't martyrs usually end up dying? Here's hoping! Jason gets his Adenosine and his heart rate immediately goes back to normal. Meanwhile, the hostages are all watching this unfold like, "we're probably lucky that we got taken hostage before we were treated by one of the quacks at this land of crazy. Next time, it's St. Sebastian's. I hear their clinic gives out free lollipops." House notices that Jason is sweating -- on only one side of his face. He says there must be a tumor pressing on Jason's sympathetic nerves. House doesn't have to worry about that happening to him, as he has no sympathetic nerves. "You have lung cancer," House says. Except that he's been wrong with every diagnosis thus far so I hope Jason's not too worried this time.
Back from break, Nurse NotCarla reports that Hadley's pulse is slow. Good. Hopefully she'll stay passed out on the couch. House calls Hadley stupid and tells Kid and Nurse NotCarla to walk Hadley around the office to get her heart rate back up. "I need proof it's cancer," Jason says. "Of course you do!" House says, irritated both at the situation and that he's being forced to actually prove his diagnoses to his patient before treating them.
