The Final Game (TV story)

✅ The Final Game was an unproduced serial intended to end Season 11. It would have revealed that the Doctor and the Master were actually brothers, explaining why the Master never sought to actually kill the Doctor. Ihe story would have ended with the Master sacrificing his life for the Third Doctor, followed by his regeneration. However, the episode was never produced due to the death of Roger Delgado (the Master) so Planet of the Spiders replaced this story as the final episode for Jon Pertwee (Third Doctor).
