A funny take on the original Star Wars movies that posits that R2 and Chewbacca are top Rebellion operatives manipulating everything behind the scenes.
20 years earlier, Chewbacca was second in command of the defence of his planet. He's there in the tactical conferences and there on the front lines and is a personal friend of Yoda's. When he needed reliable people to join the embryonic Alliance, who else would Yoda turn to but his old friend from Kashykk[sic]? Given his background, there is no way that Chewie would spend the crucial years of the rebellion as the second-in-command to (sorry Han) a low-level smuggler. Unless it's his cover. In fact, Chewie is a top-line spy and flies what is in many ways the Rebellion's best ship.
