Can you elaborate on this angle I have embolded? I must be too old, I was at best a fair-weather SW fan and have no idea what Gary's input into the series was (something to do with science or religion?). I barely remember his name in the credits. As for Oatsdad's analysis above, Luke would not be the first guy attracted to a long lost sister he never knew existed, and whose identity has yet to be revealed. Oedipus did not know at first that he was marrying his own mother, and there have been many instances in literature and film since.
