House’s ex-girlfriend Stacy Warner (guest star Sela Ward) returns - not to be with House, but to get his help for her ailing husband. While House decides whether or not to take the case, Cuddy instructs him to substitute for a sick professor and present a lecture to a class of medical students. As he weaves the stories of three patients (including guest star Carmen Electra) who all present with a similar symptom, House gives a lecture the students will never forget. In the end, they come out with a broader understanding of diagnostics and House’s team comes out with a greater understanding of him.

Andie, a 9-year-old terminal cancer patient, is brought in after suffering from a hallucinogenic episode. Wilson convinces House to take the case, but he and his team struggle to diagnose what caused the hallucination. Andie handles the reality of her terminal medical situation remarkably well - so well that House questions the sincerity of her bravery and considers the possibility it may be a medical symptom.

While a meningitis scare overwhelms the resources and staff of Princeton-Plainsboro Teaching Hospital, House zeros in on a single patient: a 12-year-old whose symptoms are similar to, but not quite right for, meningitis. Cuddy gives them an hour to crack the case before pulling their medical manpower to treat the countless patients taking over the waiting rooms, but when they discover something quite unexpected, House, Foreman and Chase must devise ingenious ways and locations to treat the girl’s delicate condition amid the chaos. Meanwhile, House asks Cameron to come back to her job now that Vogler is gone, but she’s got a surprising requirement.

Kayla, mother of two young girls, doubles over with stomach pain during her children’s talent show and is rushed to Princeton Plainsboro Teaching Hospital. Six months later, Dr. Chase and Dr. House are being counseled by Stacy in preparation for a disciplinary hearing aimed at determining if either Chase or House made a mistake that ultimately led to Kayla’s death and her family’s subsequent lawsuit.

While Princeton-Plainsboro Hospital is rife with rumor and speculation about House’s imminent date with Cameron, House apparently scares a meek clinic patient into having a stroke. The team must navigate their way through the patient’s odd proclivities, overbearing "friend" and reluctant parents in order to stop the strokes and try to save the guy’s life. All the while, Wilson, Cuddy and the team offer House dating advice and lay odds on the outcome.
