ABOUT ROBERT CHASE
Dr. Robert Chase is a fictional character on the Fox medical drama House. He is portrayed by Jesse Spencer.Robert Chase was the longest-serving member of House's staff, despite being a young doctor reportedly 26 years old at the start of the show (cf. "Cursed"), although he says he is 30 in the episode "Autopsy". His tenure on House's staff is is hinted at in the episode "All In", where he describes details of previous work with House to Dr. Eric Foreman, citing himself as speaking to the doctor that was around before Dr. Allison Cameron.
Chase was very attached to his job, and was willing to go to extreme lengths to keep it when it became threatened by Princeton-Plainsboro Teaching Hospital Chairman of the Board Edward Vogler in Season One. He leaked the details of House's rather unconventional (and sometimes illegal) style of solving cases to Vogler over the course of five episodes, leading to a major rift between him and House when discovered although House seemed to have suspected him from the beginning.
House says in the pilot episode that he only hired Chase because his father made a call, but considering Chase and his father had a horrible relationship, coupled with House's personality, this might not be the case. In the episode "No Reason," House, while hallucinating, is startled by a quick diagnosis on Chase's part, but covers by saying that he "wouldn't have hired him if he wasn't smart." This earns the sarcastic response from Jack Moriarty, "Right. 'Cause you've got nothing but respect for him," which becomes particularly worthy of note when "Moriarty's" identity is revealed. In any case, Chase and House have a highly complicated relationship.
In the differential diagnosis that takes place in every show, Chase's suggestions almost always tie into something the patient of the week has done to themselves, usually due to drugs or risky behavior. It could be argued this is driven by his own past experiences with self-destructive behavior, a want to please House, or a combination of both. Chase is often the only one to show amusement at his boss' callous jokes. Early on in Season Three, Michael Tritter, a driven cop attempting to convict House of drug possession, sets Chase up to look as if he betrayed House. Chase responds by stepping up his loyalty to his boss, but during this, House is going through painful drug withdrawal and takes much of his anger out on convenient targets, Chase included. When Chase physically tries to stop him from leaving the hospital (to prevent House from making a serious mistake regarding a patient), House snaps and punches him in the face, knocking him to the floor. An irate and bruised Chase seems ready to wash his hands of House at last, vowing to Dr. James Wilson that he will not wait for his mentor's approval anymore.
Chase seems to have a soft spot for child patients; this leads to a dilemma in the episode "Autopsy" where a dying nine-year old girl asks him for a kiss before she dies. He had a bond with another nine-year old in the episode "Cursed," said a heartfelt prayer before performing an autopsy of an infant he failed to save (cf. "Forever"), pretends to pull an alien chip out of a young boy in the episode "Cane and Able," and is frequently asking parents about their young children and dealing with kids. In various episodes, he has been very unsympathetic towards the overweight, to the point of Foreman flat-out asking him if he hated fat people. Chase supplied no direct response to the query. In a surprising move during the season three finale, Dr. House fired Chase from his position at the hospital.
ABOUT GREGORY HOUSE
Dr. Gregory House, M.D., is a fictional character and protagonist of the Fox medical drama House. He is played by Hugh Laurie. House is a maverick medical genius (often quoted as "medicine's most brilliant mind") who heads a team of young diagnosticians at the fictional Princeton-Plainsboro Teaching Hospital. He has been called a "misanthrope" and a "curmudgeon"in fact, "curmudgeon" was named one of the top television words of the year in honour of the character.
House's thigh, scarred from infarction surgeryHouse commonly expresses a profound and innate disappointment in the fallibility and inferiority of other people. His crankiness is commonly attributed to the chronic pain in his leg (the result of an infarction in one or more of the quadriceps muscles in his right thigh), for which he requires the aid of a cane. However, according to former girlfriend Stacy Warner, he was "pretty much the same" before the infarction.
House takes Vicodin frequently for the pain in his leg and usually while dealing with a case that wastes his time or annoys him. Whether he takes it too frequently was the subject of an entire episode, "Detox", as well as a story arc in the third season. He agrees that he has an addiction, but when his boss, Lisa Cuddy, interprets this to mean he admits to having a problem, colleague Dr. James Wilson has to explain the difference to her. House claims the addiction is not a problem because it does not interfere with his life, despite at least one medical problem being attributed to it during "Top Secret".
ABOUT THE RELATIONSHIP
Of the three fellow currently working under House, Robert Chase has been there longest. In the first season, when Edward Vogler puts his job at risk, Chase is shown to be willing to do whatever it takes to keep his job, even if that means betraying House himself. While on paper Chase stays morally spotless, merely reporting the Diagnostic Department's activities to a superior, he blatantly betrays House's trust. House finds out and there is tension between them for a time, but by Season Two, the entire department seems to have put the incident behind them, as can be seen in the transition from the episode "Kids" to "Love Hurts", and it is barely ever referenced again.While House has said he believes Chase "loves" him, there has been no outward reciprocation or particular attachment on House's part. However, in the finale of Season Two, House appears distinctly ruffled by the idea of not being able to depend on Chase, and in "The Mistake" House makes a sincere effort to keep Chase on staff after he makes a serious error that could lead to his dismissal. During the episode "Half-Wit,", Chase cries as he hugs House as he and the rest of the team believe House is dying of inoperable brain cancer.
In Season Three, Michael Tritter investigates Chase's history and learns that he has betrayed House before. Tritter sets Chase up to make it appear as if he is conspiring against House again. Mortified, Chase attempts to smooth things over with House, but House (who is in a fit of drug withdrawal) wants nothing to do with him either way. After this, Chase realizes a patient's diagnosis on his own and races to the hospital exit to tell House to cancel the little girl's unnecessary surgery, which if performed would leave her crippled. House tells him to get out of his way, and when Chase does not comply, House hits him in the jaw, knocking him down. Only after this does House realize Chase is right and cancels the surgery. Afterwards, a bruised Chase bitterly tells Wilson that even though he had the answer and did everything right, it still wasn't enough to earn even a modicum of House's respect. In this conversation, Chase states that he will no longer seek House's approval. However, in the next episode, Chase is quick to reassure House that he, and his jaw, are fine and things seem to be back to normal.
House respects Chase's instincts and ability to use logic to figure out what's going on through his powers of observation. House admits this to himself in his dream when he was shot and later on to Chase directly when Chase figures out House cancelled Foreman's interview.
At the end of Season Three, Chase is fired by House; House justifies it by saying that "it is time for a change".
