Edward Vogler Edward Vogler (
Chi McBride) is the billionaire owner of a pharmaceutical firm and, in a season 1 story arc, became the new chairman of the board of
Princeton–Plainsboro Teaching Hospital (PPTH), a position he gained through a $100 million donation to the hospital. 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 conform to Vogler's increasingly capricious demands (including an order for House to fire one of his fellows) and even publicly bashed Vogler's company at a press banquet, Vogler gave the board an ultimatum: fire House, or lose Vogler's grant. After losing Wilson from the board, and a last ditch and impassioned motion from Cuddy for the board members to put the hospital's independence ahead of Vogler's donation, the board voted to retain House, therefore losing Vogler and his $100 million. Fox demanded a bad guy to be added to the show, a few months before
House went on a Christmas hiatus. However, the producers decided not to extend the character's story arc. In a video, David Shore said: "Chi McBride is so larger than life. He’s literally just a physically imposing person, and we just wanted someone who could really clash with House, somebody who could be emotionally and physically and psychologically imposing as he is and could go head to head with him."
Stacy Warner Stacy Warner (
Sela Ward) was Dr. House's former live-in girlfriend (for five 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 okay with House) to be close to her husband during his recovery. House and Stacy's relationship has been strained due to his relentless attempts 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 House does not allow himself happiness. The aftermath of this botched affair left House in a stark depression. Stacy did not appear on the show again, until the series finale "Everybody Dies". In the episode "Son of Coma Guy", when playing a questions game with a patient to make a diagnosis, House admitted that he had been in love once. He said they met when she shot him in a game of paintball, Doctors vs Lawyers. Presumably, House was talking about Stacy. When the patient asked if that was the only time he'd ever been in love, House avoided answering and changed the subject. Stacy made her final appearance, her first in six seasons, in the series finale "
Everybody Dies" as both a hallucination of House and an attendee of his funeral. Here, Stacy revealed that she had "never stopped loving" House.
Michael Tritter Detective Michael Tritter (
David Morse) is one of House's clinic patients. After House refuses to run tests at Tritter's request and insults him, Tritter trips House. House agrees to the tests and tells Tritter he has to check his temperature to rule out infection. House proceeds to use a rectal thermometer, and his supposed reason for using the rectal thermometer over a normal mouth thermometer is Tritter's chewing of nicotine gum, since oral readings can be affected by
food and drink. House then leaves the room on a pretense with the thermometer still inserted in Tritter's rectum; House intentionally never returns and Tritter endures the rectal thermometer for two 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 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 also interviews 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. Chase is concerned that this makes Foreman and Cameron 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 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, House enters rehab. Tritter confronts him in rehab to see if he was really going through with it. When the charges against House were dropped at the trial, because Cuddy fabricated evidence that acquitted House, Tritter wished House good luck and said that he hoped he was wrong about him. Tritter did not appear on the show again.
Amber Volakis Dr. Amber Volakis (
Anne Dudek) is an interventional
radiologist featured in the fourth and fifth seasons as House's main antagonist. In House's competition to hire a new team, she is #24. Volakis is willing to do anything to get the job, including acts of dishonesty. This is first seen when she apparently quits the competition and convinces a group of applicants to imitate her, rather than be humiliated by House; she returns moments later admitting it was a ruse to thin the herd. She is subsequently referred to as "Cutthroat Bitch" and "Bitch" by House throughout the season, and is even referred to as such on House's caller I.D. After the characters stop using this nickname, she is still almost always called by her first name, unlike the rest of the characters. She sometimes coerces Chase and Cameron, now reassigned to different departments of the hospital, into helping her. Her persistence and unorthodox approaches initially win her praise, but she is ultimately eliminated because House feels she cannot accept being wrong, something he says she would need to be able to accept on a regular basis if she were to work for him. Amber returns in "Frozen", when House discovers that she is Wilson's new girlfriend, a fact Wilson had been trying to conceal from House. House and Amber quickly develop an adversarial relationship, bickering over "shared custody" of Wilson. In the two-part season 4 finale (episodes "
House's Head" and "
Wilson's Heart"), Amber is involved in a bus crash alongside House, who noticed symptoms of an unknown disease in her immediately before the crash. House later realizes that she is suffering from poisoning from her use of flu pills containing
amantadine, along with the kidney failure caused by the crash. She dies in Wilson's arms due to multiple organ failure. Amber is absent from only two episodes in the fourth season. Amber re-appears as House's hallucinated helper at the end of the episode "
Saviors," and in the succeeding episode "
House Divided," where House continues to see her. She is revealed to have become a part of his unconscious, now risen from his insomnia and his guilt over failing to foresee Kutner's suicide and over her death earlier. House first seeks to shut out his hallucinated friend with sleeping pills, but later engages proactively with her to figure out a case. A misdiagnosis is almost fatal to the patient; as is Chase's case of anaphylactic shock at the bachelor party House throws for him, when Chase licks a stripper unknowingly covered in strawberry flavored body butter, to which he is allergic. House imagines "Amber" may have been trying to murder Chase, he takes the sleeping pill at the end of the episode, but he finds he is still seeing her, and in the next episode "
Under My Skin" it appears his hallucinations are due to his use of
Vicodin and he must detox. In the season finale, after it is exposed that House hallucinated his detoxification, Amber re-appears. Amber made her final appearance, her first in three seasons, in the series finale "
Everybody Dies", as a hallucination of House and not able to participate in the team. Critic Kelly Woo, from
TV Squad, placed her on #3 on her list of "Seven new characters that worked" just below
Losts
Benjamin Linus and
Desmond Hume.
Lucas Douglas Lucas Douglas (
Michael Weston) is a
private investigator. He is hired by House in the fifth-season episode "
Not Cancer" to spy on House's team and gain information about them. Among other things, he finds out about a secret bank account started up by Taub's wife of which Taub is unaware. Impressed by his thorough efforts, House decides to put Lucas "on retainer." Next, in "Adverse Events", House uses Lucas to gain information about Cuddy's personal life. Lucas, though, had also begun to take a romantic interest in Cuddy. In "Lucky Thirteen", House uses him to spy on Wilson because he suspects he was lying about where he was one morning. Lucas finds out that he's dating a
hooker and that he's doing drugs. House then figures out Wilson was trying to throw him off because he knew Lucas was following him. It is also revealed that Lucas got the keys to all of his fellows' houses. House also used him to dig up info about Foreman, but could not find anything interesting. Michael Weston reprises the role of Lucas during season six in the episode "
Known Unknowns". Lucas had begun dating Cuddy. In the season 6 finale, Cuddy breaks off her engagement with him and ends their relationship so that she can be with House.
Rachel Taub Rachel Taub (
Jennifer Crystal Foley) is Chris Taub's wife and has appeared in several episodes, mostly dealing with her husband's infidelity. She reveals to Chris that she is pregnant in the seventh season. In season eight, she wants to move across country with her new boyfriend and her and Taub's daughter, but Taub tries to stop them.
Sam Carr Sam Carr (
Cynthia Watros) is Wilson's first wife, whom he starts dating again in season six. They break up in season seven.
Dominika Petrova Dominika Petrova (
Karolina Wydra) and
House get
married so that she can be allowed to live in the U.S. Dominika first appeared in the
season 7 episode "
Fall from Grace", where in an effort to make Lisa Cuddy jealous, House announces that he will be marrying Dominika, in order for her to get her green card. Their marriage ceremony takes place in House's apartment, with
James Wilson and
Lisa Cuddy as witnesses. Although this ceremony causes Cuddy to break down, their ceremony is a success, prompting Dominika to reveal to House that she actually does like him, to which House replies that he doesn't sleep with married women. Dominika is not seen for almost a season; however, she returns in
season 8's "
Man of the House", due to her upcoming marriage status interview. In order to successfully appear to be a married couple, House and Dominika spend more time together, learning information about each other's lives. Although they are successful, a slip-up involving Wilson results in their getting caught. However, they make a deal resulting in Dominika being legally obligated to live in House's apartment. For the next four episodes, House and Dominika grow close and it appears that both of them share some level of romantic affection for one another. Dominika aids House in his efforts to find out more information about his favorite prostitute in "
We Need the Eggs" and their relationship only grows stronger, leading House to throw away the letter informing her that she has been approved for U.S. citizenship. In the following episode, "
Body & Soul", before Dominika discovers House's deception, she seduces House, revealing the magnitude of her feelings for him. After she learns of his deception, she leaves him, in tears. Dominika makes her final appearances in the series finale, "
Everybody Dies". Here, a hallucination of House reveals his desires regarding love. It is revealed through House's subconscious that it was his desire to enter a true romantic relationship with Dominika, although House never reveals his true feelings to her. She is last seen at House's funeral, delivering a eulogy.
Unsuccessful applicants for fellowship • Dr. Jeffrey Cole (a.k.a. Big Love, Black Mormon) (
Edi Gathegi) is #18. A graduate of
Brigham Young University, Cole is a practicing
Mormon which draws the ire of Dr. House, who is
atheist. Cole eventually punches House when House calls
Joseph Smith a "horny fraud." This impresses House. Dr. Cole is also African-American, and a surrogate for House's racial epithets towards Dr. Foreman. Cole refused to drop out of the running when Amber deceitfully encouraged candidates to quit rather than be humiliated by Dr. House. Cameron believes Cole is a decent and principled man, and gives him advice on how to gain House's respect. In the episode "Guardian Angels" it is revealed that he is a single father, and does not know where his child's mother is. In the episode "
You Don't Want To Know", Kutner mentions that he has babysat for Cole's son. He is nicknamed "
Big Love" in reference to
HBO's popular series about Utah
polygamists. House fires him because he was willing to compromise with Cuddy instead of subverting her authority. His medical specialty is
Medical Genetics. • Dr. Travis Brennan (a.k.a. Grumpy) (
Andy Comeau) is an
epidemiologist. He is #37. Brennan was invited back for the second round of cuts, and survived again when the females' team was eliminated for failing to properly supervise the patient, resulting in his death. He offered the final (though incorrect) diagnosis of
eosinophilic pneumonia of this patient, and House authorized treatment. House nicknames him "Grumpy", and he tends to be gruff and straight to the point. It is revealed he worked with
Doctors Without Borders for eight years, making his experience in third world countries provide him more awareness of exotic pathologies. He interviewed for this job to settle down to a life in New Jersey with his fiancée, though from his own testimony and the mirroring of a patient he would rather be back working in third world countries. He was forced to quit in the episode "Whatever It Takes" after House discovered that he was poisoning a patient in order to provoke studies into cures for
polio. When House confronted him with this, he told Brennan he had no intention of firing him, but ordered him to quit instead. House gave him a few moments to leave and then had Foreman call the police. • Henry Dobson (a.k.a. Scooter/Ridiculously Old Fraud/
Bosley) (
Carmen Argenziano) was a former
Medical School Admissions Officer. He is #26. Dobson refuses to perform even basic tests on patients, saying that, with his advanced age and the other applicants' inexperience, they have more to prove; however, he shows a very gifted medical mind. House pulls Dobson aside and reveals the truth: Dobson is not even a doctor, and never even graduated from medical school or learned to do medical procedures. Dobson admits that during the 30 years that he worked in the admissions office of
Columbia University's medical school, he audited every one of its classes. House, impressed by his gall as well as his knowledge, allows him to stay on to compete for a job as an "assistant". Dobson argues age should not matter (jokingly claiming he is 21) and demonstrates he is as effective as any of the real doctors by finding a way to break into a patient's home to acquire key information and offering a diagnosis of cancer for a patient that House agreed with and scheduled surgery for. However, in "97 Seconds", House does reveal to the remaining team members that one of the remaining "applicants" is not even really a doctor, although they have yet to realize who this is. Ultimately he is dismissed when House finds that Dobson's thought processes are too similar to his own, illustrated when Dobson explains that "you don't need someone to tell you what you're already thinking" before House can explain the dismissal. Nicknamed "Scooter", "Ridiculously Old Fraud", and "
Bosley", after the ''
Charlie's Angels'' character in an episode where House was pretending to be Charlie and the other applicants the Angels. ==Minor characters==
