George O’Malley, portrayed by T.R. Knight, was one of the original interns on Grey’s Anatomy, known for his sweetness and relentless loyalty. In season five, he is killed off after being hit by a bus and later dies in the hospital, a twist that blindsided many viewers who had come to see him as a permanent fixture of the show. Trade and entertainment coverage at the time highlighted how the decision to kill George was tied in part to the actor’s desire to leave, but the writers chose to push the exit into darker, more tragic territory rather than a simple departure. Fans have since pointed to his final scene, where he is unknowingly saved by his former colleagues, as one of the most haunting and heartbreaking moments in the series.
