Excellent work. I've always thought it should end on "and the Jedi don't?"

Still can't stand the name Darth Plagueis though.

Have you considered changing it to "Darth Vader"? That way, it suggests that Anakin is stepping into this ancient sith's shoes to learn this power. And Palps dubbing him Darth Vader later on doesn't seem so random and based on nothing.

Palpatine: Henceforth, you wil be known as Darth.........um.............Vader. Yeah Darth Vader

Anakin: You're really pulling these names out of your ass aren't you?
