Lucy, a six-year-old girl, starts showing symptoms that generally occur in much older patients.
Meanwhile, Dr. Cuddy and Dr. Wilson go on a date.
This episode contains examples of the following tropes:
- First Period Panic: Implied. When the medical team is searching for the right diagnosis on a 6-year-old girl, find a bloodied piece of clothing hidden in her room. At first, they consider it coming from physical or sexual abuse at the hands of her relatives, but doctors find the blood to be menstrual. The girl has apparently already hit puberty due to abnormally high hormone levels, the source of which is later found to have been testosterone cream the father was taking and unknowingly passing to his children via sweat.
- Healthcare Motivation: The other Patient of the Week is revealed to be mimicking the symptoms for someone without health insurance. When the male patient is asked for a urine sample, he pretended to the bladder shy, and brought a sample from home instead. But when House sees that the urine sample shows that he's pregnant, it obviously meant that it wasn't the man's urine sample.
- Hot Teacher: Janie, the teacher at the daycare that is having an affair with Deran, the patient's father.
- Lousy Lovers Are Losers: Deran felt he was too old to be able to sexually satisfy his younger lover, so he began to rely on testosterone cream so he wouldn't disappoint her.
- May–December Romance: Deran is much older than his lover Janie. Dr. House characterizes the relationship as "May-October at worst." This turns out to be a plot point since he started to use testosterone cream because he couldn't keep up in bed with her.
- Mistaken for Pedophile: The team starts to suspect Deran is sexually abusing his daughter, but House is convinced otherwise due to the father's consent in letting them examine her, something he wouldn't allow if he was guilty. He turns out to be right, but Cuddy is still furious he didn't report it.
- Missing Mom: The patient's mother has passed away around a year ago, meaning she had no female figure she could have consulted with about her First Period Panic, which caused further complications when she tried to keep it a secret from her father and brother.
- Patient of the Week: Lucy, a 6-year-old girl that passed out in school due to an increase in her testosterone level causing her to enter puberty prematurely.
- Parent with New Paramour: The episode ends with Deran finally introducing his children to his new girlfriend.
- Precocious Crush: The patient's brother Jasper ends up growing one on Cameron, which is actually a hint that he's actually suffering from an excess of testosterone, much like his sister.
