House unwisely asks Wilson what Cameron is doing at PPTH, and Wilson denies that Cameron is working there, saying last he heard, she was engaged to Chase (...awkward) and living with him in Arizona. "These visions are freaking you out," Wilson says. House maintains that the fact that he saw Cameron with blonde hair means that he didn't make it up, but this just gives Wilson more to psychoanalyze House about, saying he must be merging Cameron and Chase in his mind. If this keeps up, Wilson says, House's next vision will be black, blonde, and wearing a vest. Wilson proves Cameron's new Arizona location to House by showing him her new phone number complete with Arizona area code, which is on his phone because she just called to tell Wilson that she and Chase put an offer down on a new house. It's been three weeks since the end of last season and they're engaged and living together? Oh yeah, that'll work out. Also, since when did Cameron call Wilson to update him on her house purchases? Why would anyone? Wilson's been living in a hotel for two years, so clearly, home-buying is of little interest to him.

Wilson continuezzz by saying House might be panicking at the thought of having to narrow down his eighteen fellows to just three, not like he's been having much trouble getting rid of them right and left so far. House takes pills. Wilson says he thinks House will end up picking three fellows he can't stand, because liking them would be too stressful. I don't really care who House picks at this point as long as it makes Wilson stop talking. Wilson is woefully overused as House's conscience and woefully underused as everything else. Anyway, the word "stress" gives House an idea.

He goes back to the classroom and says they're going to stress Greta's liver to find out if it's working right. Twin 1 has a problem with this, but House ignores her to ask Kumar why he's sitting behind her when he was fired. Kumar denies being fired, and is wearing his number necklace upside-down so it now says 9 instead of 6. Very clever, Kumar. Anne needlessly tattles on Kumar while 29 finds this all very amusing. Either way, Kumar gets fired. Again. Thing 1 continues her protest but is interrupted by 13, who has no problem with killing patients with silly tests and suggests shooting Greta up with Vitamin D and sticking her on a tanning bed. House says that's a good idea, but the "test" isn't specific to Greta's liver, so it won't work tell them what they need to know. Kumar tries again from the doorway: "We could get her wasted." He didn't bother turning his necklace around to make it a sideways 6. Also, he's wearing a hoodie. What doctor wears a hoodie under his lab coat? Not my doctor, that's for damn sure. Kumar says that how long it takes Greta to pass out from the alcohol will tell them how well her liver's working. "I like you, Number 9," House says. Kumar grins. Anne thinks this is so unfair. I guess next time, she'll think of ways to help the patient instead of ways to screw everyone else over.
