ProtoKun7 said:Despite the fact that Rory never existed, the effect he had on certain events would stay, which is why the ring is still there. If he never existed, he wouldn't have pushed the Doctor out of the way of Restac, remember?
My point was more to the fact that the photo of Rory & Amy was still on her desk, however he never existed.
And the effect he had would not have happened.
That's what i'm saying about an acceptable hiccup in any time-traveling plot line.
