Give Peace a Chance (Grey's Anatomy)

"Give Peace a Chance" is the seventh episode of the sixth season of the American television medical drama Grey's Anatomy, and the show's 109th episode overall. Written by Peter Nowalk and directed by Chandra Wilson, the episode was originally broadcast on the American Broadcasting Company (ABC) in the United States on October 29, 2009. Grey's Anatomy centers on a group of young doctors in training. In this episode, Dr. Derek Shepherd (Patrick Dempsey) performs an operation on a hospital technician's "inoperable" tumor, despite the objections of the chief of surgery, Dr. Richard Webber (James Pickens, Jr.). The episode was designed to revolve around Dempsey's character. Katherine Heigl (Dr. Izzie Stevens) was absent from the episode, as she was filming the 2010 romantic comedy Life as We Know It. Mark Saul, Jesse Williams, and Nora Zehetner returned as guest stars, while Faran Tahir made his only appearance. "Give Peace a Chance" won Wilson an NAACP Image Award, and received positive reviews from critics, with Tahir's character receiving particular praise. The initial episode broadcast was ranked #4 for the night with 13.74 million viewers, and a 5.2/13 Nielsen rating/share in the 18–49 demographic.
