What about George’s concept that Anakin was the son of Palpatine. He even had a reveal scene like Empire where Palpatine reveals it to Anakin, it was in an earlier script draft of Revenge of the Sith.

I’m not sure if that was the original path to corruption in the script, Palpatine’s appeal to Anakin about the power of the dark side. The dark side is so powerful it allowed Palpatine to create a vergence with midichlorians, the chosen one to destroy the Jedi. Then in the film it became saving Padme from death and the fear of loss.

Honestly i never liked the idea that Palpatine is Luke’s grandfather and created the Skywalker line.

I guess it is still sort of in Revenge of the Sith but implied with the scene at the opera. It doesn’t really come out and make it explicit.

I have no idea what the original concept for the Jedi Knights in the Clone Wars was or what George originally had in the story for the Emperor and Anakin. Because it changed through the years, Palpatine wasn’t even a Sith in the original film or even seen. He was more a corrupt politician, A Nixonian Wizard of OZ. And Vader wasn’t Anakin Skywalker until 1979. So any idea about the old republic and Ben and Anakin was probably very vague or done while writing return of the jedi. And i’m sure the prequels were completely different in 1983 whatever he had down on paper or in his head for the story. Lucas is a genius, but some stuff just came out of nowhere when he resumed working on them in 1994, like Jar Jar or Qui Gon, and yeah midichlorians.
