Common Misconceptions and Grey’s Anatomy Deaths

Plane Crash Survivors and Fatalities
The Season 9 plane crash is a major event. Confirmed fatalities include Lexie Grey and Mark Sloan. George O’Malley died earlier in Season 5, not in the crash. Other characters, such as Arizona Robbins and Callie Torres, sustained serious injuries but survived.
