I know that they're probably not going to go there with this? But the events after the Big Bang 2 don't really quite contraindicate it, so I'm really hoping that Rory is still an independent Auton, possibly getting some help from the Doctor to make sure the Nestene can't take him over. Because, I mean, how awesome would that be, to have him running around, ready and willing to break out the hand-gun when the situation requires?
I submit that that would be so fucking awesome.
