Outside, the SWAT team takes its position against a wall and starts setting up the explosives.
Inside, Hadley holds the syringe up to her vein, but can't bring herself to shoot up. "Sometimes you just have to trust people!" she says. True, but maybe not when it's the SWAT team who want you dead as quickly and cleanly as possible. Jason aims the gun at her, and Hadley again tries to shoot herself up. But she still can't do it. "I don't want to die!" she says, surprising herself. Jason doesn't care. He aims the gun at her head. "I don't want to die!" she repeats. Should've thought of that sooner, moron.
It turns out that Jason doesn't want Hadley to die, either. He puts the gun down and grabs the syringe and shoots up just as the SWAT team blows a hole in the wall. The stunt doubles used for the wall explosion scene were pretty pathetic, I must say. Actually, just the Jason double is bad, as his face has been painted bright white for some reason.
The SWAT team enters to find both Jason and Hadley on the ground. House checks on her and surprised to find that she's still alive. Jason is taken away. Hadley says he didn't make her take the drug after all. I hate Jason.
House is lead to the lobby by a triumphant SWAT team. Cuddy's there. House downs some Vicodins, then turns to see Jason being lead away. Before he goes, House tells him to check his breathing. It's fine. He got his answer and his cure. Now he's off to jail forever. Idiot, but at least he won't have to pay all those medical bills.
And Hadley is looking angelic as she recovers in a hospital bed, hooked up to a dialysis machine. Oh, good. She's alive. Fan-fucking-tastic. Foreman's at her side when she wakes up. He tells her she'll be just fine after a week of dialysis, and apologizes for leaving the differential. Hadley doesn't really care. Instead, she asks about the Huntington's drug trial. Hadley loves taking drugs and doesn't want to stop! And maybe now that she's come to terms with her terminal disease or whatever, she'll spend some time in the fucking background already.
