During Thursday's episode of the ABC medical drama, T.R.

George died in the season 5 finale after sacrificing himself to save a woman from being hit by a bus. In a recent interview with Deadline, Vernoff explained that George was her "first idea" when she first started thinking about having previous characters reappear on the show. Grey's Anatomy: George O’Malley Returns in Meredith Grey's Dream as She Battles COVID-19 ABC "When I called Ellen [Pompeo] and said, I have this idea to have you having these dreams on the beach, and I want to get someone amazing, like T.R,. Ellen was like, 'Yes, get T.R., and also Patrick.' That was the evolution of that," she explained. "Ellen and T.R. are close, and George and T.R. were both always favorites of mine, and so he was my first idea of, as a fan, who do I want to see again? I wanted to see George, so that’s where it started."

As for Knight's reaction to coming back to the show, he said it was an experience "unlike any other." "Going to the set that day, because we shot on the beach and it was an early call, I’m driving in the dark because you want to be early... It was just wave upon wave of happiness, of joy, of Krista. She was there the entire day. Linda Klein, she was there all day. And then to have Ellen, and Chandra, and Jim, of course, and all the other familiar faces that were there, too, because there were quite a bit of crew that were there still. To have all of that, it was just unlike any other experience I’ve ever had in my entire life, in my 47 years," he continued. Similar to keeping the return of Derek Shepherd (Patrick Dempsey) under wraps, the majority of the cast was unaware that George would be coming back to set. George was referred to as Thatcher (Meredith's father) in the script during table reads, and Vernoff said she thinks "there are members of the cast who still don’t know this is happening." T.R.

"I’m so lucky to have a friend like you," Pompeo responded in the comments.
