Season 2 (Grey's Anatomy)

Season 2 began airing on Sunday, September 25, 2005, and ended on May 14 and May 15, 2006 with a three-hour finale spanning both nights. The first season had originally contained 14 episodes, representing ABC's original midseason order for the show. However, it was decided to end the season early because ABC executives wished for the show's first season to end with ABC's Desperate Housewives (which had the time slot before Grey’s Anatomy for the first two seasons).

Summary
Rather than condensing or throwing out plot lines, Grey’s Anatomy producers chose to end the first season with the ninth episode and save the following episodes for the second season. Episodes 10-14 were then held and broadcast as the first five episodes of Season 2. ABC ordered 22 episodes in addition to the five being carried over, bringing the total number of episodes for the second season to 27. Bring the Pain, which aired as the series' 14th episode, has been cited in series creator Shonda Rhimes' blog as having been originally intended as the first season finale. The second season focuses on Meredith and Derek's relationship, which comes to an abrupt halt when it is revealed that Derek is married to neo-natal surgeon Addison Montgomery. Izzie and Alex embark on a relationship of their own (although cut short when Izzie falls for heart patient Denny Duquette), as do Cristina Yang and Preston Burke. Doctor Bailey becomes pregnant, and more is revealed about her personal life. On some of the weeks airing after its highly-watched February 5, 2006 post-Super Bowl episode, the program attracted more viewers than its lead-in, Desperate Housewives. Once the second season ended on May 15, 2006, the show had two previously recurring actors, Sara Ramirez (Callie Torres) and Eric Dane (Mark Sloan), join the regular cast. The series' opening credit sequence was also dropped by the last half of the second season, replaced by a title card displayed at the end of the first act and credits displayed over the opening of the second act of each episode.
