SuperMom's liver tumor confuses House. They must have missed a reason for it to be where it is. He says that they're missing the human element of the case, and asks the Cottages to tell him what they know about SuperMom. "She's a people-pleaser," says Cameron. "She doesn't like to let people down." "She never fights with her husband," House adds. "She turns to drugs instead of asking for help to manage her life," Chase adds. Interesting how each of them see aspects of SuperMom that are most relevant to their own personal issues, eh? Very clever, writers. House wonders why, if SuperMom is having trouble managing her life with just the one kid, she would be trying so hard to have another. The answer involves her people-pleasing, drug-loving, non-confrontational ways: she doesn't want to have a child, but also doesn't want to tell her husband that, so she's been taking birth-control pills along with her fertility drugs. I can understand why SuperMom doesn't want StuporDad's StuporGenes getting passed on, but her taking birth-control pills instead of just telling him the truth totally baffles me.
House wakes SuperMom up by slamming his cane down on her bed frame. He asks her if she would like a hysterectomy along with her liver tumor surgery, which is totally unnecessary. You see, the liver tumor is a harmless adenoma caused by the birth-control pills. It's benign and it will go away once she stops being such a weirdo. But SuperMom would rather have the surgery than tell StuporDad that she doesn't want another child, and won't admit to taking birth-control pills. House says that he's going to cancel her surgery, and that she can have fun trying to explain why to her husband.
