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.
