With that out of the way, Andres is vomiting again. And he punches Mrs. Andres! And there's blood in his urine! Here's what I think is going on: I think she's been poisoning him. She probably used her flower business to grow deadly nightshade or something and has been slipping it into the meals she's been cooking him for the past six years. She likes to feel needed. Münchausen by Proxy. I always think it's Münchausen by Proxy on this show.
Adams says they should increase the sedation and return the antiemetics. Park thinks he punched Mrs. Andres for sleeping with that guy. House suggests that it's okay for her to do that, and Adams insists that cheating on a marriage is always bad. She kind of goes on about it, because that's her primary character trait; she's "the one who gets mad when people cheat." They run into Foreman, who says Andres should have stayed on the antiemetics. House says the punch gave them viable diagnostic information about his emotional problems and anyway, House wanted him sedated. So either way, House blames Foreman.
Park reads a recently-hidden card that says "The patient will punch his wife." Foreman is not impressed, because House clearly wrote that prediction after it happened. Then House reads a card where Foreman accuses him of writing that card after the fact. And he has a picture of himself with last week's paper. Then there are some more diagnoses that lead to plasmapheresis, which is a technique, not a disease. They're going to go all plasmapheresis all over Andres.
Mrs. Andres sends Joseph away. He kisses her on the forehead and leaves. She tells Chase they're not having an affair and that it's really hard doing this herself. Chase asks when she last got a full night's sleep, and she says it's been three years. "People who are sick are not the only ones who need to be taken care of," says Chase, and he sends her away, promising Andres will be fine for one night.
House, Adams and Park study Wilson's patient's blood tests. House waxes rhapsodic about the sex drive and how great it is. Park suggests spinal problems, but Adams goes with psychological intimacy issue. Suddenly, Park mentions that she's "tapped over thirty guys" that she never spoke to again because she lives next to a Jewish frat. Because Park's character trait is "The one who says unsettling things." Adams thinks the patient is better off without a sex drive, if only because she's immune to most advertising. House appears to get a new idea. After he leaves, Adams asks Park, "Thirty?" Park claims that everybody lies, but that doesn't tell Adams whether the actual number is above or below thirty.
