Imagine being just a average teenager who's friend with one wacked out scientist , well that's what everyone tells me but I don't think he's that bad. Although it could be worse. Now Docs gone missing and left a strange letter in his place? This is going to be a long day. (AU where Marty has met Doc and their timelines come to a chaotic stop. What could happen when he's sent back to the wild west . Another gun drawl. Told from Marty's pov)
