Grey's Anatomy: Season 5, Episode 24

5 - 24: Now or Never

The doctors focus on the victim of a near-fatal traffic accident who is disfigured and unable to speak. Meredith discovers it's George, who was hit by a bus while saving the woman who accompanied him to the hospital. Izzie recovers her memory and tells Alex that she loves him before losing consciousness. The episode ends with both George and Izzie flatlining and meeting up with each other in a heaven-like scene, with no definite indication of whether either or both are dead or alive.
