 House often clashes with his fellow physicians, including his own diagnostic team, because many of his hypotheses about patients'illnesses are based on subtle or controversial insights. His flouting of hospital rules and procedures frequently leads him into conflict with his boss, hospital administrator and Dean of Medicine Dr. Lisa Cuddy (Lisa Edelstein). House's only true friend is Dr. James Wilson (Robert Sean Leonard), head of the Department of Oncology. During the first three seasons, House's diagnostic team consists of Dr. Robert Chase (Jesse Spencer), Dr. Allison Cameron (Jennifer Morrison), and Dr. Eric Foreman (Omar Epps). At the end of the third season, this team disbands. Rejoined by Foreman, House gradually selects three new team members: Dr. Remy "Thirteen" Hadley (Olivia Wilde), Dr. Chris Taub (Peter Jacobson), and Dr. Lawrence Kutner (Kal Penn). Kutner makes an appearance late in season five and then reappears in season 8 episode 22. Chase and Cameron continue to appear in different roles at the hospital until early in season six. Cameron then departs the hospital, and Chase returns to the diagnostic team. Thirteen takes a leave of absence for most of season seven, and her position is filled by medical student Martha M. Masters (Amber Tamblyn). Cuddy and Masters depart before season eight; Foreman becomes the new Dean of Medicine, while Dr. Jessica Adams (Odette Annable) and Dr. Chi Park (Charlyne Yi) join House's team.
