I need to know if he will return after "The End Of Time"... Emphasis on "need". He can't die, right? He's the arch nemesis of The Doctor. I know John Simm is pretty busy nowadays, but if Master DOES come back, would he be reincarnated? Ugh, I have so many questions. Season 8 of Doctor Who has just started with Matt Smith, and I heard that Matt might be retiring from Doctor Who (which might just be a rumor), so do you think after the new Doctor comes around, Master might just pop up and surprise everyone?
