I was just watching ANH, and something came up. When ObiWan and Vader are having their duel in the deathstar Vader tells Obi, "You should never have come back here." or something close to that. Now this is probably going too far, but do you think that maybe the Death Star is in Ep3, somehow. Maybe an earlier version, since Obi immediatley knew it was a space station when Han thought it was a moon. Maybe Obi and Vader have their duel on the death star. Im probably wrong, but just humour me.
