Now What?

House and Cuddy are exploring the ramifications of those feelings and attempting to make a real relationship work. Meanwhile, due to a colleague’s illness, Princeton Plainsboro is left without a neurosurgeon on site, threatening the hospital’s accreditation as a Level 1 Trauma Center. As the team attempts treatment to get their sick colleague back to work, they discover there is more to the illness than they originally suspected and turn to House for direction. Instead, House remains elusive, leaving the team on its own.

Unwritten

A children’s novelist tries to kill herself, but is thwarted when she has a seizure. House, a fan of the books, puts her on psych hold but has to deal with a patient that is eager to die rather than be cured. Meanwhile, House worries that he’ll lose Cuddy because they have nothing in common.

Dead & Buried

The team learns that their 14-year-old patient is suffering from more than teen angst when her physical symptoms worsen. Despite Foreman’s firm opposition, House becomes obsessed with solving a peculiar case of a deceased four-year-old patient, which gets him into serious trouble. Meanwhile, Park tries to get Chase (Jesse Spencer) to admit the reason behind his recent obsession with grooming.

Whatever It Takes

Based on practically no information and no medical history about a mystery patient sent by the CIA, House is using some unorthodox methods to diagnose and treat him. Meanwhile the remaining candidates are questioning Foreman’s judgment.

The Itch

The team must treat an agoraphobic who refuses to leave his house, and have to work around Cuddy, who is less than thrilled at having hospital equipment relocated. Meanwhile, House is plagued by an itch, and Cameron and Chase have relationship issues.

The C-Word

When House and Wilson disappear off the grid for several days, without explanation, the team is left to deal with a difficult case concerning a 6-year old with numerous problems and complications, including an overbearing mother who also happens to be her physician.

Living the Dream

House is convinced one of the actors on his favorite soap opera “Prescription Passion” has a serious medical condition after observing his symptoms on television. House decides to intervene and take matters into his own hands, but both the actor and House’s own team dismiss House’s assessment and do not believe there is anything wrong with him.

Detox

While trying to figure out why a young patient won’t stop bleeding, House takes Cuddy’s challenge and goes off Vicodin for a week in exchange for no clinic duty for a month. If House and his team can’t determine the source of his patient’s blood loss, the 16-year-old car accident victim will die in a matter of days. As House’s withdrawal symptoms become more and more severe, his directives for his patient are more harsh and risky than usual, forcing Foreman and Cameron to fear he may not be thinking clearly enough to save the patient’s life.

Charity Case

House and Park treat a patient, Benjamin, who collapsed after making a surprisingly large charity donation, and come to suspect that the altruistic behavior is a symptom of a deeper disorder. When the patient offers to donate an organ for another patient, the doctors must convince Dr. Adams to help them confirm whether Benjamin is in his right mind or not.

Emancipation

While Foreman takes on a pediatric case on his own, the rest of the team deals with a 16-year-old factory manager and emancipated minor who collapses at work. When Foreman’s patient takes a turn for the worse, he’s forced to question whether he can deal with the situation on his own, or if he needs House’s help.

Body and Soul

House and the team take on the case of a young boy who has violent dreams of being choked, and then wakes up but still can’t take in air. Meanwhile, Park is having intimate dreams involving co-workers, which causes the team to question whether or not there’s significance to what each of them dreams. Dominika discovers House has been keeping a secret from her and Wilson drops a bombshell on him.

No Reason

As House and his team are working on the diagnosis of a man with a giant, swollen tongue, the husband of a former patient walks into House’s office and shoots him. House continues to treat his patient from his ICU hospital bed with the shooter, who has been shot by hospital security and hand-cuffed to his bed, as his roommate. When the after-effects of the shooting begin to impact House, he starts to question his own ability to diagnose properly. As his patient’s body deteriorates, House struggles through his self-doubt and must trust his team to find a way to solve the case.

Knight Fall

House and the team take on the case of Sir William, a "knight" in a closed-off community of men and women living according to the ideals of the High Renaissance. As the team searches the medieval village for environmental factors contributing to Sir William's rapidly deteriorating health, Thirteen and Sir William debate the acts that define honor and loyalty, especially in regard to the "queen" of the community, one of Sir William's most frequent visitors. Meanwhile, Wilson starts over with an ex.

Ignorance Is Bliss

On the eve of Thanksgiving, House and the team take on the case of James Sidas, an exceptionally brilliant physicist and author who traded his successful career for a job as a courier. For the ailing patient, intelligence is a miserable burden that has prompted depression and addiction, and this, coupled with a myriad of strange symptoms, nearly stumps the team. Meanwhile the doctors at Princeton Plainsboro wrestle with strained personal relationships.

Everybody Dies

Facing a 6-month jail term, and the realization that he won’t be there for Wilson at the end, House finds himself examining his entire life while contemplating a dismal future without his best friend.

Love Hurts

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.

Locked In

A man awakens in New York after a bicycle accident unable to move or communicate in any way. House, himself injured in a motorcycle mishap, occupies the hospital bed next to Lee and quickly annoys the doctors treating them both by insisting that Lee has “locked-in” syndrome.

Birthmarks

While en route to his father’s funeral, House must help the team with a differential diagnosis on a young Chinese girl who has collapsed under mysterious circumstances.
