GREY'S ANATOMY - "These Arms of Mine" - A documentary film crew visits the hospital six months after the shooting to document the road to recovery for doctors and patients. The camera lenses follow Derek, Owen, Mark & Callie as they ambitiously perform a rare arm transplant surgery, Meredith helps Cristina put on a brave face for the cameras, and Bailey's patient, Mary, returns for her surgery -- which marks the first time they've all seen of each other since that fateful day -- on "Grey's Anatomy," THURSDAY, OCTOBER 28 (9:00-10:01 p.m., ET) on the ABC Television Network.
