So that's the end of the Amelia Pond era. There was a distinctly fairy-tale quality to most of the episodes, and now I'm wondering how much of what we saw was stuff that actually happened and how much was the story the Doctor told little Amelia when he went back. Did the Doctor really travel with Amy and Rory, or was it all just a tale told to a little girl?
Throughout the fifth season, I wondered if the show was actually taking place in Amy's imagination. There was the timing glitch in "Victory of the Daleks" where Bracewell's plans for an oxygen/gravity bubble and blaster rays were implemented on Spitfires and launched into space in a mere twenty-two minutes. The story-book improbable Starwhale and its kindness towards children. That staple of children's nightmares, vampires. A history lesson in a visit with a great artist and the sad tragedy of a misunderstood monster. And through it all, that crack in time and the goofiness of the "Big Bang".
I will be very impressed if Moffat planned all this from "The Eleventh Hour". If he always intended the whole thing to loop back on that one scene with Amelia waiting and the subterfuge that led us all to believe it was just a dream.
If this is the case, who knows how much of what we've seen so far of Doctor Eleven has been real? Maybe he never came back for Amy and Rory twelve years later. Maybe he never married River Song.
The eleventh Doctor might be a different person when he's not telling tales about himself.
It's just idle speculation. I'm probably wrong. But if the Doctor seems more serious in the rest of the season; if he seems somehow more constrained by reality; if he never again mentions the Ponds or his marriage to River Song, the explanation just might have something to do with a Timelord filling a little girl's head with whimsical stories like a crazy old grandfather.
Have to say I thought there was something bigger going on in S5 as well, as well as the Spitfire stuff, there was also the speed with which a handful of people set up a village wide CCTV system in the first Silurian episode, and I did wonder if none of it was real...actually I think it was just somewhat shoddy writing/production in both cases.
