Weeping angels actually feed on “sadness energy,” rather than time energy. And Moffat is a weeping angel. He’s positioned himself in a job that can allow him to generate more sadness and thus continue feeding forever.
Hey, it’s a rare theory post! I’ve been seeing a lot of Rory=Master theories floating on the dash right now, and I think we’re forgetting the episode “The Doctor’s Wife.” Idris definitely seemed to have taken a liking to Rory, even calling him “the pretty one.” If she already knows that Rory is the Master (as she likely would, and as implied by the theory about the distress call in “The God Complex”), she wouldn’t be so fond of him.
TARDIS approves of Rory. I don’t think he’s the Master.
