Izzie is decked in her prom dress, reminiscent of the season 2 finale where she boards the elevator before discovering that her fiance, Denny, has died.

Three years later, Izzie and George are both on the brink of death. The elevator door opens and it is George standing there, waiting for her. Her best friend. She smiles because she is relieved to see him. She is ready to die.

In the OR, Hunt shouts, "We're losing him!" George is already dead. He is just waiting to escort his best friend to the afterlife.

But the chief ignores her DNR and they start bringing her back to life. She realizes that it is not yet her time to step off the elevator.

Izzie is going to live. For now, at least.

Amazing two hour season finale. But I hate how they left it to my interpretation to satisfy the ambiguity caused by Grey's Anatomy's highly unfulfilling cliffhanger. Until Season 6...
