"Obi-Wan never told you waht happened to your father."
"He told me enough! He told me you killed him!"
"No. I am your father."
"Nooooooooooooooo!!"
Luke and Darth Vader engaged in a fierce duel and as a show of his superiority in swordplay and the force, Darth Vader severs Luke's hand. Seducing the Jedi to the dark side by offering Luke a change to destroy the Emperor and bring order to the galaxy were not enticing enough for Luke as he staunchly refused the offers. As a final blow, Darth Vader reveals himself to be Luke's father. Rather than join the dark side, Luke throws himself down the shaft. He manages to hold onto a weather vane and use the force to contact Leai who arrive just in time to rescue Luke with Chewbacca and Lando.
