On a note of reflection
First off, loved the story and thank you for alerting us to it.
And on a reflective note, it may explain why our history hasn't changed,
as there are those who "patrol" the time lines. Then again, if our history
changed, would we know it?
And what about the theory that every action everyone and
everything does branches off into an infinite number of alternate
scenarios? Would it even be practical or possible to patrol all
of them?
