Sneak Peek: 'Grey's Anatomy'

"Grey's Anatomy"'s Seattle Grace Hospital is back in action: When Izzzy ( Katherine Heigl ) tries to talk to Alex ( Justin Chambers ),  he immediately thinks she is trying to break up with him, so when she admits she sees dead people (Denny, Jeffrey Dean Morgan ) he is relieved and tells her to say hi! Then a death row inmate ( Eric Stoltz ) is admitted, which angers Derek ( Patrick Dempsey ) and causes the rift between Meredith ( Ellen Pompeo ) and Cristina ( Sandra Oh ) to deepen. In the meantime,  Callie ( Sara Ramirez ) and Mark Sloan ( Eric Dane ) create their own recovery program to fight their inappropriate attractions to members of the opposite/same sex, and Dr. Bailey ( Chandra Wilson ) teams up with Seattle Grace's new pediatric surgeon, Dr. Arizona Robbins ( Jessica Capshaw ) to save a young patient.
