House season 2

The second season of House premiered on September 13, 2005 and ended on May 23, 2006. During the season, House tries to cope with his feelings for his ex-girlfriend Stacy Warner, who, after he diagnosed her husband with acute intermittent porphyria, has taken a job in the legal department of Princeton-Plainsboro Teaching Hospital.

Sela Ward's chemistry with Hugh Laurie in the final two episodes of the first season was strong enough to have her character return in seven episodes of the second season.
