Cut to House giving Mary yet another ultrasound, although this time it's slightly lower. And instead of intracranial bleeding, we see a fetus. Whoops! Looks like Mary forgot to tell her partner to put his swimming cap on before entry. House explains that pregnancy causes a lot of changes in one's body, and sometimes it just goes "haywire" and the blood clots all over the place. When red blood cells try to squeeze past the clots, they get all shredded up. Mary remains coldly unaffected by the whole thing, giving the picture of her baby only a cursory glance before returning to her "you don't know me!" glare. House says that he knows how these national swimming competitions work; you're with a bunch of older kids in hotel rooms with no parents around and someone sneaks in some beer, and then you lose your virginity before you start high school. "It wasn't like that," Mary says, and I was totally expecting her to reveal that she and her coach are in love. But no, she just says she "wanted it," although the guy "turned out to be a jerk." House says that he's also a felon. Mary says that he might be a statutory rapist, but he's not a plain old regular rapist. She knew what she was doing. House says that they have to abort the baby and give Mary plasmapharesis. Mary's only problem with that is that she doesn't want her parents to know. House says he's sure that someone old enough to bleed out of her vagina is also well able to handle an abortion. It's not his call anyway; New Jersey law does not require parental consent for abortions.
House limps out of the room and informs the parents that Mary has TTP, and that it's treatable. She'll need "minor surgery to remove the underlying cause," and then the treatment for TTP, and she'll be fine. Of course, the parents ask about the surgery, and House will only says that it's an "abnormal growth" in her abdomen that will require a "simple surgery" the hospital does "all the time." And he's sorry, but he can't be any more specific than that. That kind of sounded like a less-than-subtle dig at parental consent laws and abortions in general. I hope not.
Mary has her abortion. A nurse soothingly rubs her shoulder and says nice things to her during the process. I can't tell because she's wearing a surgical mask, but I'm betting it's not Nurse Brenda.
