I will not fight you.
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 attacks Vader ferociously, eventually backing him onto a railing and cutting off his arm. He stands over Vader for a moment.] [laughing]
Good! Your hate has made you powerful. Now, fulfill your destiny and take your father's place at my side!
[turning 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.
