Robert Chase, M.D. is a fictional character on the Fox medical drama House. He is portrayed by Jesse Spencer. His character was a part of the team of diagnosticians who worked under Gregory House until the end of the third season when House fires him. However, he resumed work at the hospital as a surgeon, and was re-hired by House in season 6. Robert Chase is the longest-serving member of House's staff. Chase has been attracted to Allison Cameron since season 3 of the show and embarks on a romantic relationship with her in "Human Error." In "Post Mortem," he left the Diagnostic Team after realizing he was in the same position as he was 10 years earlier, unlike all of the other former members of the team. However, in the series finale, he rejoins the hospital as the new Head of Diagnostic Medicine, replacing the (supposedly) dead House. Characterization Chase is Australian and was born around the year 1979. His Czech father, Rowan Chase, was a wealthy and world-renowned rheumatologist who had emigrated to Australia from Czechoslovakia before Chase was born. Chase is portrayed as an enthusiastic follower of House during the first 3 seasons, often supporting his opinions and carrying out his orders without question. He was raised Catholic, and in the Season 1 episode "Damned If You Do," it was revealed that he attended seminary before becoming a doctor, but was kicked out for having sex with the wife of a groundskeeper. He seems to trust House the most and sometimes takes part in House's morally questionable plans when the other members of the team have refused, showing a situational application of ethics and a flexible stance on morality. This leads to heated arguments between Chase and Foreman, who is quick to disagree with House and eager to prove him wrong. Chase is regarded by most characters as someone who will do anything to protect his job. This is mostly due to an incident in season one when Chase, fearing for his job after House had been made to fire someone from his team, told Edward Vogler of House's illegal actions. However, as the show progresses, Chase begins to show his real trust and respect for House. Having been on the team longer than anyone else, Chase cares for House, as shown by the hug in the Season Three episode "Half-Wit." When Michael Tritter is looking for
