Emperor Palpatine: If you will not be turned, you will be destroyed. Young fool. Only now, at the end, do you understand. Your feeble skills are no match for the power of the dark side. You have paid the price for your lack of vision.
Luke Skywalker: Father, please! Help me!
Emperor Palpatine: Now, young Skywalker, you will die.
Darth Vader: No. No! (picks Emperor up and throws him over the rails toward the core...)
Emperor Palpatine: Good. Use your aggressive feelings, boy. Let the hate flow through you. Good! Your hate has made you powerful. Now, fulfil your destiny and take your father's place at my side.
Luke Skywalker: Never. I'll never turn to the dark side. You've failed, Your Highness. I am a Jedi, like my father before me.
Emperor Palpatine: So be it, Jedi.
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.
Luke Skywalker: 3PO, tell them if they don't do as you wish, you'll become angry and use your magic.
C-3PO: But, Master Luke, what magic? I couldn't possibly.
Luke Skywalker: Just tell them.
C-3PO: (C-3PO speaks to Ewoks...) You see, Master Luke? They didn't believe me, just as I said they wouldn't. (Luke makes C-3PO float) Wait, wait. Put me down! Help! Somebody! Somebody, help! Master Luke! R2, R2, quickly! Thank goodness.
Luke Skywalker: Thanks, 3PO.
C-3PO: I never knew I had it in me.
Luke Skywalker: Obi-Wan. Why didn't you tell me? You told me Vader betrayed and murdered my father.
Ben Kenobi: Your father was seduced by the dark side of the Force. He ceased to be Anakin Skywalker and became Darth Vader. When that happened, the good man who was your father was destroyed. So what I told you was true, from a certain point of view.
