There is no single, definitive set of rules for time travel. It's a completely fictional premise that can work however a particular writer wants it to work for the purpose of their story.
If you read the arguments in the "City" thread, you wouldn't be making this statement. In short, I know it is fictional, which means writers must fall back on logic. If they toss that out the window, then they can't craft a logical series of events in their story, turning it on and off at will to suit their needs and using the audience as a punching bag. "Just because" would invalidate most, if not all, of the posts on this forum.
