And, frankly, Jack's "Not again" to me really doesn't (to me) actually imply that the Master was just merrily having a good time having him killed every five minutes - but that he was hard to control and kept GETTING SHOT. So, pretty sure I'm running counter popular fanon with that. The Doctor I can see probably waiting around to have the oldness reversed because he knew what the plan was. Jack? *shakes head* If he was standing around for a year biding his time, I'll eat my hat.
