Spoilers for season 2, particularly Reichenbach.
I read this "Richard Brook" post a while ago, probably in December 2012. It bothered me. I wanted to argue with it A LOT.
Short answer: I think this is the crackpot theory. Like Bruno Bettelheim on fairy tales, some reads well, and then the rest just goes ka-blooey.
But if you're looking for some lovely screen caps of RF -- with a couple thrown in from other eps -- that's a jackpot.
