Okay, so you know how in RJ F. Paul Wilson added himself into the book as P. Frank Winslow? And that he wrote the jake Fixx novels that eirily mirror Jack's own life? Well I just watched an episode of Supernatural this morning that was very similar. A guy was writing these novels based on the lives of Sam and dean, he never met them and thought they were just fiction, but everything he wrote down actually happened to them. He turned out to be a prophet of god.
See the parallels? Just yet another reason why Jensen Ackles should be Jack.
