House Wiki

The third season of House premiered on September 5, 2006 and ended on May 29, 2007.

At the beginning of the season, the main storyline centers around House's temporary lack of pain in his leg due to ketamine treatment after being shot in the previous season finale. Later in the season, he leaves a stubborn patient in an exam room with a thermometer in his rectum. Because House is unwilling to apologize, the patient, police detective Michael Tritter, starts an investigation around House's Vicodin addiction. The third season concluded with a cliffhanger finale, in which House fires Chase, Foreman leaves as he already resigned and doesn't change his mind and Cameron resigns, leaving House without a team for the fourth season.

David Morse joined the cast for seven episodes as Tritter. He was cast for the role after having previously worked with House'​s creator David Shore on the CBS show Hack.


Season 3 of House M.D. returned to television in September 2006, and contained 24 episodes. House, M.D. - Season Three was released to DVD on August 21, 2007.

Although the series seemed to settle back into a regular pattern, by the season's end it was clear that the series was going to undergo a fundamental change for Season 4. First came the resignation of Foreman, followed by the departure of the rest of House's team, leaving House to himself and opening the door to bring in new characters.


House recovers from his gunshot wounds, but despite his pain temporarily disappearing and the fact that his leg is working again, he is soon back on Vicodin. He runs into a particularly difficult patient at the clinic, who turns out to be a police officer, who then makes it his business to get House sent to jail for possessing Vicodin illegally. Unfortunately, House has used Wilson's prescription pad to forge his own prescriptions, even though Wilson has been supplying him with Vicodin freely. House nearly goes to jail, but Cuddy then perjures herself in court to have the charges dismissed.

Allison Cameron looks at her poor social life and decides to fill the hole in her sex life with Robert Chase. She demands a "no strings attached" relationship, and everyone predicts that Chase will dump her at some point, leaving the vulnerable Cameron heartbroken. Instead, it's Chase who becomes emotionally attached. When he professes he wants a deeper relationship, Cameron cuts off the sex. Chase won't let the matter drop and institutes the tradition of I love you Tuesdays, reminding Cameron how much he likes her every Tuesday, and insisting that given her empathetic nature she can't possibly not have feelings for a man she's worked with for three years.

Work continues normally until Foreman, fearing that he's becoming too much like House, decides he wants to leave the hospital for good. Despite Cuddy and Wilson imploring House to get Foreman to stay, House instead fires Chase for no reason and then Cameron decides to quit as well, leaving House without a team to help him. However, when Cameron realizes Chase will soon be out of her life, she quickly changes her tune and shows up on his doorstep.

This season also features the last appearance of Nurse Previn in the episode Que Sera Sera. It also marks the only appearance of Foreman’s mother Alicia Foreman.
