Darth Vader: There is no escape. Don't make me destroy you.
Darth Vader: Luke, 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: I'll never join you!
Darth Vader: If you only knew the power of the Dark Side. Obi-Wan never told you what happened to your father.
Luke: He told me enough! He told me you killed him!
Darth Vader: No. I am your father.
Luke: No. No. That's not true. That's impossible!
Darth Vader: Search your feelings, you know it to be true!
Luke: No! No!
