Over in Giles's room, Giles gasps for air while the Cottages tend to him. Machines beep all over the place. Chase says that the only way to save Giles is to "intubate him -- stat!" I think the "stat" went without saying, but it doesn't really matter since Giles's DNR prevents them from doing it at all.
Meanwhile, in a random elevator, Giles's manager/girlfriend/whoever is bringing her client/boyfriend/whatever a whole bunch of brand-new CDs. "Someone likes music!" a doctor says. I can't believe that guy went to school for an extra eight years.
House enters the room and sees the Cottages standing around while their patient dies. Foreman says that the immunoglobulin House recommended has put Giles in respiratory failure. "WE did this," he says. "We killed him." House says that no one's dead yet, grabs the intubation gear, and shoves a tube down Giles's throat to the mild protests of Foreman. Wow, this is like the first time we've seen House do hands-on doctor work except for those autopsies. Cool. House gets Giles artificially breathing as the woman walks in. "What did you just do?" she asks. "He saved his life," Cameron tattles.
Back at the office, House says the fact that the immunoglobulin therapy made Giles worse means that he doesn't have multifocal motor neuropathy. "Now, what's really wrong with him?" he asks. "What's wrong with you?" Foreman says. Oh, so many things. Foreman says that Giles had a legal document forbidding them from intubating him. House responds that he was hoping Foreman would be a good enough doctor that his patient wouldn't need to be intubated. Ouch. Furthermore, Giles may not have been mentally competent when he signed the DNR because his low thyroid levels were "making him sad." "His thyroid levels were a little --" Cameron starts, all ready to jump to the defense of her rule-flouting boss. She always did fall for the bad guys. Foreman cuts her off and yells at her not to defend him. House says that Giles signed the DNR to prevent a "slow, painful death" from ALS. But it was the immunoglobulin that put him in respiratory distress, so House feels pretty good about his decision. Then again, he felt good about recommending the immunoglobulin. Foreman says that this is all because House won't allow his mistake to kill a patient. Au contraire, says House. This is Foreman's case, so officially, it's Foreman's mistake that almost killed the patient. He accuses Foreman of not wanting to "look bad" in front of his old boss. Foreman changes the subject to the fact that House assaulted Giles. "I won't do it again," House says. "Yes, you will!" Foreman immediately responds. House says that is true, and therefore this debate is pointless. Foreman looks to the other Cottages for support, but Chase is really interested in his shoes and Cameron is looking at a pretty bird right outside the window. No support will be forthcoming. Foreman storms out in a huff.
