Uuuuuh...yeah. No. I understand Lucas likes to make this claim that he had it all planned out like this from the beginning, but there's quite a bit that goes against that. All of it from his own pen-to-paper drafts. Here's just one example of what I'm talking about: ‘The Adventures Of Luke Starkiller’: Peter Mayhew releases pages from his 1976 Star Wars script And there's no way I'll ever believe that Leia was always intended to be Luke's sister. As was stated, there's sexual tension between Luke and Leia in both ANH, and ESB. I honestly believe that Leia was intended to be a non-related Force-user. Re: Yoda's claim, "...there is another." Funny that only he considered that and not Obi Wan who knew of BOTH, as was demonstrated in the later-written prequels. And the claim that Vader was mostly a "thug" for Tarkin (and the not-seen Emperor) in ANH is also valid. While I would say both Vader and Tarkin are equally the primary antagonists in ANH, the references to the Emperor make THAT more of a plausible movie set-up for a future plot device than the "brother-sister" connection which seemingly came out of NOWHERE even in 1983.
