Luke Skywalker: I've accepted the truth that you were once Anakin Skywalker, my father.
Darth Vader: That name no longer has any meaning for me!
Luke Skywalker: It is the name of your true self; you have only forgotten! I know there is good in you. The Emperor hasn't driven it from you fully! That was why you couldn't destroy me. That's why you won't bring me to your Emperor now.
