Darth Vader: "There is no escape. Don't make me destroy you. 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 Skywalker: "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 Skywalker: "He told me enough! He told me you killed him!"
Darth Vader: "No. I am your father."
Luke Skywalker: "No... no. That's not true. That's impossible!"
Darth Vader: "Search your feelings, you know it to be true!"
Luke Skywalker: [cries in anguish] "No! No!"
