Okay, so you know how the angel sent Amy and Rory back in time where the Doctor couldn't go because of the paradox they had just created. Well, why the hell didn't he let the angel send him back in time too? If he cared about them as much as he claims, he should have done that. He would have been able to be with them the rest of their lives then. Plus he would long outlive them, definitely more than enough to survive until he gets back into his tardis. Seriously, he just stands there bitching and moaning but he doesn't do anything. Get your shit together Doctor.
