The fourth season of House, also known as House, M.D., premiered on September 25, 2007 and ended May 19, 2008. Having previously fired Chase, and with Foreman and Cameron quitting, House starts a competition between 40 applicants for the vacant positions. He eventually narrows them down to seven, firing one each episode. In the episode "Games", he fires Amber Volakis, hiring Dr. Chris Taub, Dr. Lawrence Kutner and Dr. Remy "Thirteen" Hadley as his new team. Dr. Foreman rejoins the team after his dismissal from another hospital. Meanwhile, Amber begins a relationship with Wilson.
