The day John Winchester walked into the Roadhouse asking for Ellen, Bill should have known. Known that only one of them would come back alive, and it wasn't going to be Ellen, because John Winchester didn't die. He was damn indestructible. It's funny, looking back on it, a bitter humor, that Bill had felt apprehension about letting Ellen go at first. But his reasoning had been completely wrong. To put it bluntly, John hadn't been laid since his wife had died and Ellen had been a looker in her day. The last thing he wanted was his life to turn into a sappy soap opera where his wife cheated on him with his best friend. But, instead of turning into a soap opera, his life turned into a living hell. His wife, his love, his Ellen, came back in a body bag. And all he was left with was a living, breathing replica of her in his daughter, Joanna Harvelle and a rotting bar that lingered with the scent of death. . Now, don't misunderstand, Bill loved his daughter to death with all his soul. But without Ellen, he dealt with the grief in the only way he could. Hunting down the very demons who had been ultimately responsible for his wife's death. So one day, he packed up his and Jo's necessities, and all things that reminded him of Ellen, and burned the Roadhouse to the ground. Bill took his daughter and ran from the past, and hunted, and ran, and hunted, and taught his daughter to do the same. Jo shot her first bull's eye at age 7, could throw knives deadly accurate by age 12, and knew how to use nearly every weapon in a hunter's arsenal by 16. Bill often found himself forgetting her gender, if not for her strong but distinctly feminine frame. Jo's personality framed that of a cocky man, and she knew well how to use her feminine wilies to her obvious advantage. The night she turned 18, Bill let her go, leaving a cell phone number in case of emergencies, her very own shiny new weapons, and a car. And so, she hunted, killing every single demon who was unfortunate enough to cross her. And across the nation, seemingly in a parallel line crossed the Winchester brothers, performing the same secretive duty. Ah, the irony of it all. Over time, Bill became the man he hated most, the man he taught his daughter to hate. Bill Harvelle turned into another John Winchester. But our story doesn't start with Bill Harvelle, nor does it start with John Winchester. Our story starts with Jo Harvelle, and her first run in with the Winchester brothers. And here's a hint, it wasn't pretty.
