Taub draws blood from Abbey, who is kind of upset to know that she gave her baby cancer, as you would be. She says she took such good care of herself while she was pregnant, and even hired a private detective to research her sperm donors. I wonder if she hired Lucas? Justine asks what will happen if her mother has something other than an autoimmune disease, as Justine has clearly seen this show before. Taub says they'll cross that bridge when they come to it, around the 51 minute mark. He leaves, and Justine apologizes to her mother for being a jealous brat out of nowhere before. "You were a great mom. You are a great mom," she says. "I don't deserve such a good daughter," Abbey says. Huh? What makes Justine a great daughter? She wouldn't even film her mother's vagina.
Taub and Cheng head to the lab to test Abbey's blood for various autoimmune disorders. Cheng reveals that House told her he was fine with hiring her, but that it was ultimately Taub's decision. "He's just saying that to set me up," Taub says. He doesn't want to offer Cheng the job if House says he's okay with it, because he knows it will only blow up in his face. "It's not lupus," Cheng says. Does she even need to get hired now? By saying it's not lupus, I'm pretty sure she's automatically a Cottage. Taub says he has to figure out what House's ulterior motive is before he hires Cheng. Cheng just shrugs and says she's at the end of the autoimmune disease tests and they're all negative. They'll have to scan Abbey for a granuloma-causing infection next.
Wilson is stuck in Cuddy's house with Rachel, who, despite pooping a lot, still hasn't come up with the dime. Wilson is digging through Rachel's poop-filled diaper with a pencil, by the way. Gross. House says that means it's time to violate Rachel's anus, and hangs up on Wilson while he collects supplies to do so from PPTH. Good thing PPTH security sucks so much that they'll just let House walk out of there with all kinds of expensive medical equipment.
Abbey is sent into the MRI (OF DOOOM!!). Taub and Foreman look at her insides while discussing Cheng and whether or not Taub should hire her. Foreman thinks he should just go ahead and do it, and whatever House might be planning can't possibly be that bad. Plus, he says, House is more interested in Cheng than he ever was in Chase or Foreman's picks, so it might work out. With that, Taub finds something in Abbey's lungs: another cancer. Wow, what a sucky coincidence. If you count Justine, that's three cancers Abbey is afflicted with.
