Well there is Splinter of the Mind’s Eye where Luke and Vader first fought, and Luke had a sort of almost romance with Princess Leia. Vader even appears to have fallen in a deep pit and died and he lost an arm.

Then Lucas made the Empire Strikes Back and it’s like Splinter is elseworlds.

Lucas dropped the love triangle between Luke, Han and Leia set up in the first film. And its barely there in deleted scenes for Empire, and when Luke is in the medical center, but Leia obvious falls for Han on the way to cloud city and at Cloud city. Lucas little bandage he put on it in Jedi, making Leia the sister, and making her the other was to this day completely unbelievable to me.

You think Luke is pining for his sister, kisses his sister. Saves her from the death star and is standing at the medal ceremony smiling at her because they were platonic. Its one of Lucas dumbest moves.
