Grey's Anatomy: Drowning on Dry Land

Izzie calls the Chief and asks him what to do about the man trapped under a car. He and Sloan guide her through drilling holes in his head so that he won't die. She does a great job, the man survives, and the Chief takes her off probation. Alex comes up with the idea to Polaroid all the patients so their families can identify them. He hopes that he has found the mysterious pregnant woman's husband, but he is mistaken. George lies to the mother whose son is missing so that she'll go into surgery. He searches everywhere for him, including the morgue. He finally finds him being operated on by Callie. Derek starts to wonder where Meredith is when he finds her coat on a patient. He finds the little girl that was with Meredith when he last saw her, and asks where she is. The little girl points to the water. Derek dives in and finds Meredith. He gets her to the hospital and tries to help revive her until the Chief makes him leave and sit outside the trauma room with Mark. The interns solemnly look on and fear the worst. Izzie tells them she believes Meredith will live, and that she also believes George marrying Callie was a mistake. Just as the Chief announces that they are losing Meredith, she sits up - in a strange bed. To her left is the man from the bomb squad who blew up in the hospital. To her right is Denny, telling her that she's dead.
