In the Big Finish Audio "Master" (Big Finish audio story), the Doctor tells an assassin a story about when he was a boy on Gallifrey. In the story the young Doctor and Master are bullied by someone called Torvic. Torvic is killed, and the listener is supposed to believe that it was the Master who did it, beginning his path to what he will become. However, we find out that it was the young Doctor who actually killed Torvic.
