Rory Who?

Alright, so major plot hole here.  Rory.So when he's erased from existence, a lot of things would be screwed up... 

In the Eleventh Hour, he has 20 minutes to save the Earth.  He does it in time because Rory shows him the pictures of the comatose patients walking about.  Without that, Earth would have been destroyed.  The Doctor would have died along with them.  Amy never would have gotten on the TARDIS.  


If Rory never existed, then Amy and Rory never would have gotten together, thus River would no longer exist.  She wouldn't take him to the Pandorica.  The Doctor would be unable to bring himself back to the universe.  The Silence may have found a better psychopath.  He could very well be dead.  If he had found the Library on his own, he'd be dead.  If he and Amy had gone to the Byzantium without her, then Amy'd be dead, and possibly him too.


They never would have gone to Venice.  She'd never remember the vampires.  Thus, the 'vampires' would have taken over at the very least Venice.  The Doctor would have noticed that, would he not?

How many would be dead without Rory Williams?  The world may never know
