Ooo, kinda like Groundhog Day? He's going around in a loop, and to get out of it he has to learn from himself and grow. Love it. And I think elisi and I were discussing the Comic Relief special and that idea of a closed loop (with the TARDIS in the TARDIS and them going around, having to take clues from themselves in order to get out) and theorizing that that might be some amount of foreshadowing for the season (that the season itself was a similar closed loop that the characters would have to learn to break).

Have you read Stephen King's The Dark Tower series? Sort of makes me think of Roland...
Nope, sorry :-\
