Yay, you posted the Clara meta! :D All the points you brought are really interesting—the pixie girl, the duality, the mirroring. The fact that the leaf might have changed is really intriguing!

"And one of the interesting things about writing the Doctor is that he's so responsive to the people around him. It's almost like left on his own his personality would slowly disintegrate. He becomes what people want him to be, a little bit. So he's Amy's Raggedy Doctor. With a different companion he becomes a slightly different man. He dresses differently."
I didn't know this quote, it's fascinating—just like the idea of both him and Clara shifting in response to the person opposite them, the themes of reality and memory… You brought up many fascinating things regarding the mirroring all throughout the show. And in Clara, this neatly clarifies a point that bothered several people, me included—that she sometimes seems too perfect. But she's not a perfect person, which doesn't exist; she is perfect for one precise point at a time, in which she becomes what others need her to be. Infinite possibilities narrowed down to a single moment. Yes! Headcanon accepted. ^_^

Love that bit about Clara not giving the Doctor answers, but reflecting at him what he needs to see to find them for himself. And the ending about the implications of the Doctor on Trenzalore is fascinating! Gosh, this makes me even more eager for Capaldi ♥

Thank you for sharing the fruit of your wonderful thinky brain! ;) ♥
