Now that might explain why he had a badge with 1990 on it, or hang on a minute. It wouldn't explain that at all.

Technically Rory was not dead, as such ... it's not
really a recurring plot device, is it. He was in peril like Sarah Jane was yesterday in the quarry. Anyway, maybe his return from the not quie undead is a hint (e.g., Amy had stopped the CPR and only thought he was dead, which means he is the Bad Wolf, the 13th doctor, his own father, Amy's child or is still a plastic nestene who can't die

. You heard it here first (actually you haven't heard it here first, as I'm sure all of these theories have been postulated somewhere

).
