How does Anakin become Vader in this rewrite?
We’ll get there. But there is an interesting twist with Darth Vader in this version of the Prequels and it relates to Obi-Wan and how it plays out to his character in the Original Trilogy and the key quote about Vader in A New Hope:
“A young Jedi named Darth Vader, who was a pupil of mine until he turned to evil, helped the Empire
hunt down and destroy the Jedi Knights. He betrayed and murdered your father. Now the Jedi are all
but extinct. Vader was seduced by the dark side of the Force.”
