Footage of Luke Skywalker and Darth Vader in the elevator on the way to the Emperor’s throne room.
Vader: So… What happened after you left Bespin?
Luke: What happened? I was without a right hand for 5 hours. What kind of a father cuts off his son’s writing hand?
Vader: This is Star Wars, Luke. Nobody writes anything in this universe. The only writing I ever see is that Aurebesh junk on Coruscant.
Luke: Dad, what are you saying?
Vader: I never learned to read, dumbass.
