We all create the stories we read, not the authors... the authors just put us on a path. Many of these shows aren't at all what their creators wanted them to be but then some suit told them "make this so we can sell more that!" The final versions of the shows ended up often being nothing at all like they were originally envisioned. So, an author can intend for something to be one way but have it interpreted another, an author can envision a story and have it changed by outside forces to meet other demands, and then an author can have his work merged with others to create something completely new... and most of this is all crafted from previous stories that inspired the author in the first place.
