[Luke surrenders himself to Darth Vader.]
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: [firmly] 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. [steps off to the side of the passageway, away from Vader] That was why you couldn't destroy me. That's why you won't bring me to your Emperor now.
[Vader turns on Luke's lightsaber and holds it up]
Darth Vader: I see you have constructed a new lightsaber. Your skills are complete. Indeed you are powerful, as the Emperor has foreseen. [turns off the lightsaber again]
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!
Darth Vader: There is no conflict.
Luke Skywalker: 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: [resigned] Then my father is truly dead.
Darth Vader: The Emperor has been expecting you.
Luke Skywalker: I know, father.
