Stacy Warner

Stacy Warner (Sela Ward) is Dr. House's former live in girlfriend (of 5 years), a Constitutional lawyer and Duke University graduate. Two years after their breakup, she married Mark Warner. She appears in 9 episodes during the run of Season 2, taking a job at PPTH (after asking Cuddy to make sure it was OK with Greg) to be close to her husband during his recovery. House and Stacy's relationship has been strained due to his relentless pursuit to prove she still has feelings for him. Mark aided House's cause by driving a wedge between himself and his wife when he suspects a brewing affair. Mark was eventually proven correct, as Stacy fell for House all over again and they slept together. As Stacy prepared to leave her husband for House, he then rejected her (stating that he could not make her happy, because he could not change). She quit her job at the hospital and went back home to Short Hills with Mark. An enraged Wilson believed House broke her heart not out of guilt for Mark (which is not his modus), but as a last ditch resort to ensure that he (House) doesn't allow himself happiness. The aftermath of this botched affair left House in a stark depression.

Mark Warner

Mark Warner (Currie Graham) is Stacy's husband. A high school guidance counselor by profession, he became a patient at PPTH against his will in "The Honeymoon" and was eventually diagnosed with porphyria by House. Mark is jealous of House and House's sharp words and actions indicate the feeling is likely mutual. Still recovering from his illness, Mark is confined to a wheelchair and attends both physical therapy sessions and psychological counseling at PPTH; during this time, Stacy and Mark began arguing with increasing frequency due to Mark's frustration with his illness and slow recovery. In "Need To Know", Mark confronted House about Mark's own fears of losing Stacy and his suspicions of House and Stacy's interactions; their confrontation led Mark to physically grapple with House and undo months of rehabilitation. House realized that Mark was willing to do the things House himself could never do for Stacy, giving him an excuse not to not follow through with their relationship. House broke up with an astounded Stacy and she left with Mark for good.

Edward Vogler
Edward Vogler (Chi McBride) is the billionaire owner of a pharmaceutical firm and former board chairman of PPTH, a position he gained through a $100 million donation to the hospital. Vogler appears in five episodes: "Control", "Mob Rules", "Heavy", "Role Model" and "Babies & Bathwater". Vogler sought to reshape PPTH into a testing facility for his firm's new drugs and saw House's maverick ways and blatant disregard for rules and authority figures as a substantial legal and financial liability. When House refused to kowtow to Vogler's increasingly capricious demands (including an order for House to fire one of his fellows) and made a mockery of Vogler's company at a press banquet, Vogler gave the board an ultimatum: Fire House or lose Vogler's grant. After an impassioned plea from Cuddy for the board members to put the hospital's independence ahead of Vogler's deep pockets, the board voted to retain House, as well as voting Vogler off the board of directors and therefore losing his $100 million.

John and Blythe House

John and Blythe House (R. Lee Ermey and Diane Baker) are House's parents. They appear in "Daddy's Boy". Mother Blythe seems to be the standard military housewife and House calls her a "human polygraph". His father John used to be a Marine Corps pilot and is incessantly honest, a trait which House seems to be quite bitter about. House's father is hard on him for not dealing with his leg better, telling him "your problem is that you don't know how lucky you are". When House was young, his father was stationed in Egypt and was stationed in Japan when he was a teenager. In episode twelve of Season 3 ("One Day, One Room"), House reveals that his father abused him as a child, making him sleep on the lawn and take ice baths.

Dr. Rowan Chase

Dr. Rowan Chase (Patrick Bauchau) is Dr. Chase's estranged father and an acclaimed rheumatologist. He left his alcoholic wife and teenage son and, some unspecified time later, remarried. He is seen in one episode, "Cursed". In "The Mistake", the character was revealed to have died of lung cancer, without ever saying goodbye to his son, and in "Forever", it is revealed that he also left his son out of his will.

Rodney Foreman

Rodney Foreman (Charles S. Dutton) is Dr. Foreman's religious father. He appears in "Euphoria, Part 2" and "House Training".

Michael Tritter

Detective Michael Tritter (David Morse) is one of House's clinic patients. After House refuses to run tests at Tritter's request, Tritter trips House. House agrees to the tests and tells Tritter he has to check his temperature with a rectal thermometer. House then leaves the room on a pretense with the thermometer inserted in Tritter's rectum; House never returns and Tritter endures the rectal thermometer for 2 hours. Afterwards, Tritter demands an apology from House for deliberately leaving the thermometer in him. House refuses, apparently spurred on by the patient's attitude, which is at least as bad as House's. Caught speeding and arrested for possession of allegedly unprescribed medication, House is thrown in jail overnight by Tritter, who searches his house the next week and finds a large amount of Vicodin. He has also interviewed House's staff looking for inconsistencies in their stories. He proceeds to tighten his vise grip on Wilson by freezing Wilson's bank account, towing his car and revoking his drug prescription rights because he wants Wilson to testify against House in court. After Tritter discovers that Wilson refuses to betray House, he turns on to House's assistants, freezing Foreman and Cameron's accounts, before talking to each one of them in turn. Foreman and Cameron refuse to testify in court about House, but when Tritter talks to Chase, he makes it appear to the hospital staff as though they had had a pleasant lunch together. This makes Foreman and Cameron seem to think that Chase has told Tritter something, although he had refused to, his only stated reason being that he would lose his job. Tritter finally succeeds in his goal however, when Wilson comes to him, requesting "thirty pieces of silver" in a symbolic statement of his decision to betray House, whom he has come to see as spiraling out of control. In the final days leading up to House's trial, Tritter confronted him in rehab to see if he was really going through with it. When the charges against House were dropped at the trial, because the judge believed Tritter was just being vindictive, Tritter wished House good luck and said that he hoped he was wrong about him. Tritter has not appeared on the show since.

Steve McQueen

Steve McQueen is House's pet rat, which he captured in Stacy's attic in "Hunting". Originally supposed to be exterminating the rat, House granted him reprieve in order to diagnose his odd neck tilt. By the end of the episode, House had determined the cause to be mycoplasmosis, aggravated by Stacy's smoking. House has used Steve McQueen for medical experimentation. In "Euphoria, Part 2", House uses Steve to do a walkthrough of the cop's home. He stated that when Steve began to show symptoms, as House saw it on his webcam, he would be hit with a "cane shaped object". Steve never showed symptoms, however, so House didn't end up killing him. Since then, he can be seen in the background in House's apartment during various episodes.
