My first question on the SciFi exchange has been marked as a duplicate, which it is clearly not. Not only does it reference it's "original" as a means of what prompted the prompted the question and to show that I already understand somewhat a remote possibility.
I mean, surely people can see the difference between:
1) How did Amy survive the crack in her wall?
2) How does Amy exist after her parents are erased from Time/Space?
Am I being dense or what?
