Dad, (Deran) is an overextended widower dad who is a zoology prof. Goes to pick up kids from daycare. Son Jasper had been accused of pushing a classmate off monkey bars because the classmate said he smelled. Daughter Lucy appears to be the ‚good girl‘, but falls to her knees, clutching for breath.

After theme/credits, Lucy is recovering from heart surgery. Chase and Cam are treating her, Deran and Jasper are in room. They discuss where Lucy has been. Some place where she’d be exposed to something moist where she’d pick up a fungus. Jasper kinda flirts with Cam (cute). Chase injects Lucy with lidocaine and she goes blind.

Later, Lucy tests positive for juvenile rheumatoid arthritis. Deran discusses this with Foreman, but now Lucy can’t speak and goes limp. Foreman deduces a stroke.

In a later scene, Chameron discuss that House is going to make them go everywhere together until they work it out. (insert your hypothesis here)

Jasper brings Cameron a floral arrangement „for helping my sister.“ Chase pulls out the card which says Congratulations on your bundle of joy“ and deduces that he stole them from a maternity patient! (hee!) Cam takes a single flower and kisses the kid on the cheek.

Later, Lucy is subjected to bloodletting.

Later, House confronts father with a bloody t-shirt found in the vent under Lucy’s bed (assuming at house, not hospital room). Accuses father of beating or diddling. Suspects diddling more. House says if not you, then someone. Where’s her brother? Brother not around. House wants to do a vaginal exam. Father distraught because she’s only five years old.

Cam does the exam for other cuts/bruises/signs of abuse. Is shocked when she starts vaginal exam. Later scene indicates it’s because Lucy has started puberty, a condition called precocious puberty. Cam posits that excess hormones caused the stroke. If they can figure out where the hormones are coming from, they can help her.

Later, Foreman and Chase are putting Lucy through a CT machine and Chase is telling Foreman that Cameron is the one who broke it off. Foreman says he’s not interested. (hey, buddy, take a number). Chase says he wanted more, but Cam didn’t share his feelings. Foreman calls him an idiot. Foreman posits that Cam is either lying or is emotionally detached. Chase asks why she’d be lying. Foreman accuses him of sleeping with her for months and still having no idea who she is. Meanwhile, they find a tumor in Lucy’s ovary.

Chase is breaking this news to the dad when Jasper asks Chase if „that other doctor“ is his girlfriend. Chase is stymied and replied that they’re very close.

House treats a clinic patient who is middle-aged and has lost feeling in her thighs. House deduces it’s because her jeans are too tight.

Cam gets on an elevator with two bags of some kind of sample from Lucy’s house. Jasper runs to the elevator to ask her about Chase being her boyfriend, and calls Chase a tool (hee!). Cam is nice to him. Jasper smacks her on the ass! (this just keeps getting better, doesn’t it?)

More stuff happens to Lucy. Meanwhile, Cam and Chase have „the talk.“ She apologizes for leading him on, and he doesn’t buy it. She says it was just for sex. Chase isn’t buying it. Jasper bursts onto the scene and flies into a blinding jealous rage, hurls himself at Chase and bites him. As punishment, Jasper is submitted to an MRI. Then he’s bled, just as Lucy was.
Both children are examined at the same time, but Lucy has an excruciating stomach pain.

Cam wants to do an invasive procedure on Lucy that House disagrees with. They’re looking for clues that link the two kids. (sorry…don’t exactly know why at this point) Cam tells Deran that her husband died of brain cancer and she knows how hard it is to make this decision. House says he can’t believe she just played the „dead husband card.“
Dad signs consent form.

Dad says the kids go to after school day care and none of the other kids are sick. House asks how he’d know that, since he’s been at PPTH for a couple of days. House takes off, with his suspicions.

House bounds into the daycare facility and asks all the kids if any of them has hair in their special place. Talks to teacher about what kind of soap they use there and then stops, looking at a rash on her upper lip. Suspects is a really recent lip wax and wonders why she’d need to run out at lunch to get it done unless the body hair was excessive.

Turns out the dad is doing the teacher, but using a male enhancement cream to keep up. It’s affecting the teacher, and the excess that he excretes through his skin is also affecting the kids, because he touches them through the normal course of the day. House assures him that if he stops using the cream, he’ll be floppy, but the kids will be fine.
