Down the hall, House is explaining that what was probably a mild allergy to start has gone untreated for so long that it's a "whopping, kick-your-ass allergy." He speculates that the allergen has to be something to which Elizabeth Mitchell was exposed in both the monastery and the hospital. Foreman wonders if it could be the tea, which is reasonable, considering that Chase was pouring it down her throat at the slightest provocation. House isn't sure, and wants to run more tests, but Cameron pipes up that Elizabeth Mitchell's immune system has gone totally bazoo and needs a rest, so they decide to put her in a "clean room," and then gradually introduce allergens to see how she reacts. Replace "allergens" with "treatments," and this is the plot of every episode.
Clean room. The Martins, wearing fugly pale yellow gowns and blue caps, tell Elizabeth Mitchell that she should start feeling better, but that she can't have anything from outside, even her Bible. Foreman and Cameron leave, and Elizabeth Mitchell asks if her sisters can come in and pray with her. Chase hyper-Aussies that it would be better for her not to have visitors. Elizabeth Mitchell looks at her sisters pleadingly and then turns over and starts to cry. Man, she's as good an actress as her wig is bad. Chase offers to pray with her, but she sobbingly says she's going to die, and asks why God has left her. Damn you, affecting scene! Where's all the Vicodin-laced banter? Chase pulls up a stool and confesses that he went to seminary school. They asked the students once what their favorite Biblical passage was. He picked 1st Peter, Chapter 1, Verse 7: "These trials only test your faith, to see whether it is strong and pure. Your faith is being tested, as fire tests gold and purifies it." Elizabeth Mitchell takes the pass and runs with it: "And your faith is more precious to the Lord than pure gold. So if your faith remains strong after being tested, it will bring you much praise and glory and honor on the day of His return." Elizabeth Mitchell cries some more as Chase tells her that she has a choice between faith and fear. She points out that having faith doesn't mean she won't die, but he counters that it will affect the way she experiences both death and life. Elizabeth Mitchell asks why Chase left seminary school. Chase: "That test. You passed. I didn't." I wouldn't have pointed a kid who was upset about failing a test in the direction of the MCATs, but I'm not Chase's dad. Great scene, though.
