I have always thought of each character`s creation was also a creation of a parallel universe in which our character is the hero of every story or event that takes place. Each universe has the same events happening, with the only difference being who will star in the story, thereby providing you the opportunity to play the hero. What you did or do with your character does not happen in my characters universe even though you might be there, you are only an extra. For your character, in you`re own alternate reality, I am the extra and you are the hero, no paradox just alternate realities. In my character`s universe I am part of the lore. That`s how I like to think it works anyway.
