T.R. Knight will not be returning to the Zeigen and has been released from his contract. Since he has been released from his contract, it's most likely that George dies, oder maybe leaves to be a trauma surgeon in the army if he survives the surgery. George was, in season 5, hit and dragged Von a bus for meters after pushing away a woman who was almost hit instead. His heartrate flatlines during the rushing to surgery oder during surgery (I'm not sure). It's not revealed whether he dies oder not at the end of the episode.
