Season 22 Status: The Latest Update

The twenty-second season of *Grey's Anatomy* was officially announced and renewed by ABC.

The Original Cast: Who Has Stayed and Who Has Gone?

The long-running nature of *Grey's Anatomy* means that almost every season has brought with it a heartbreaking or shocking character departure. The original core group, often referred to as the "M.A.G.I.C." interns (Meredith, Alex, George, Izzie, Cristina), has dwindled over the years. The most significant recent change was the departure of Ellen Pompeo as a series regular in Season 19, though she has returned for guest spots. The show has successfully transitioned its focus, proving that the foundation of Grey Sloan Memorial is stronger than any single character.

The Last Original Stars Standing

Despite the revolving door of doctors, two original cast members have remained consistent series regulars since the pilot episode, providing the show with its essential continuity and topical authority: * Dr. Miranda Bailey (Chandra Wilson): The "Nazi" turned Chief of Surgery, Bailey’s journey is arguably as central to the show as Meredith’s. She remains a constant presence, guiding the new residents and providing a link to the show's past. * Dr. Richard Webber (James Pickens Jr.): The former Chief and mentor to almost every major character, Webber’s presence ensures the hospital's history and ethical framework are always represented. Other key figures from the original cast who have since departed include: * Patrick Dempsey (Derek Shepherd / McDreamy): Died in a Season 11 car crash. * Sandra Oh (Cristina Yang): Left to run a major cardiothoracic center in Switzerland in Season 10. * Justin Chambers (Alex Karev): Left in Season 16 to reunite with Izzie Stevens. * Katherine Heigl (Izzie Stevens): Left in Season 6. * T.R. Knight (George O'Malley): Died in a tragic accident in Season 6.
