Luke Skywalker: Come with me.
Darth Vader: Obi-Wan once thought as you do. You don't know the power of the dark side. I must obey my master.
Luke Skywalker: I will not turn, and you'll be forced to kill me.
Darth Vader: If that is your destiny.
Luke Skywalker: Search your feelings, Father. You can't do this. I feel the conflict within you. Let go of your hate.
Darth Vader: It is too late for me, son. The Emperor will show you the true nature of the Force. He is your master now.
Luke Skywalker: Then my father is truly dead.
Darth Vader: The Emperor has been expecting you.
Luke Skywalker: I know, Father.
Darth Vader: So, you have accepted the truth.
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've 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.
Commander: I tell you this station will be operational, as planned.
Darth Vader: The Emperor does not share your optimistic appraisal of the situation.
Commander: But he asks the impossible. I need more men.
Darth Vader: Then perhaps you can tell him when he arrives.
Commander: The Emperor's coming here?
Darth Vader: That is correct, Commander, and he is most displeased with your apparent lack of progress.
Commander: We shall double our efforts.
Darth Vader: I hope so, Commander, for your sake. The Emperor is not as forgiving as I am.
Darth Vader: There is no escape. Don't make me destroy you. You do not yet realize your importance. You have only begun to discover your power. Join me... and I will complete your training. With our combined strength... we can end this destructive conflict... and bring order to the galaxy.
Luke Skywalker: I'll never join you!
