As we know, actor T.R. Knight doesn’t return for the September 24 Grey’s Anatomy season six premiere, but it appears his character, Dr. George O’Malley, will.

“Transplant doctors descend on Seattle Grace because it's revealed that George was a registered organ donor," according to a source on the Grey’s Anatomy set.

“His colleagues are still reeling from George's death and are fighting with transplant doctors to stop them from taking his lungs, liver, corneas and bone marrow."

"It's only when everyone hears what lives will be saved that George's friends start to get some perspective on his death,” says the source to Life & Style Weekly.

George's funeral scene is also said to take place early this season.

Who knows how reliable any of this actually is, but according to the source, all of the scenes with George O'Malley were shot using special effects and makeup.

"It's one of the goriest scenes they've ever done because you literally see each of these organs get pulled out of his body," says the supposed on-set insider.
