The bit about Amy and Rory's house door, I though the doctor bought the house and the car for them?

I think there's only one timeline in there, it's just that the doctor's been traveling alone (or maybe he went ahead and did the stuff with River off cam) for 200 years, just popping in and out of our present time so it looks like it hasn't been that long from our perspective.

and I hope the God Complex was really the end of the Williamses' time as companions. It's not that they overstayed their welcome with me (a bit, though). But I wanted them to have a happy ending, especially since Amelia's story was set up like a fairy tale. I don't want them to get left behind in an alien planet or lost in another timestream or caught dead in a fixed point in T&S.
