Total Script Re-Write by Raggetymanftw reviews
This is sort of part of the Eliza Winchester series, but not really. Eh, it's hard to explain really. I just hope you enjoy it. It has nothing to do with the 200th episode, if that's what you gathered from the title. This is mostly rewriting history, the Winchester way. Please review! :D There is going to be swearing and some background destiel.
