Return of the Jedi1983

Vader:
[searching for Luke in Palpatine's chamber] You cannot hide forever, Luke.

Luke:
I will not fight you.

Vader:
Give yourself to the dark side. It is the only way you can save your friends. Yes, your thoughts betray you. Your feelings for them are strong. Especially for... [pauses] Sister. So, you have a twin sister. Your feelings have now betrayed her too. Obi-Wan was wise to hide her from me. Now his failure is complete. If you will not turn to the dark side, then perhaps she will.

Luke:
[revealing himself] NEVER!!! [attacks Vader ferociously, eventually backing him onto a railing and cutting off his right hand. He stands over Vader for a moment.]

Palpatine:
[laughing] Good! Your hate has made you powerful. Now, fulfill your destiny and take your father's place at my side.

Luke:
[looks at Vader's severed hand, then turns to face the Emperor, throwing away his lightsaber] Never. I'll never turn to the dark side. You have failed, Your Highness. I am a Jedi, like my father before me.

Palpatine:
[angrily] So be it... Jedi.
