Return of the Jedi1983

Palpatine:
Welcome, young Skywalker, I have been expecting you. You no longer need those. [uses the Force to detach Luke's cuffs] Guards, leave us. [the Emperor's guards leave the room] I'm looking forward to completing your training. In time, you will call me "Master".

Luke:
You're gravely mistaken. You won't convert me as you did my father.

Palpatine:
Oh no, my young Jedi. You will find that it is you who are mistaken, about a great many things.

Vader:
[hands Luke's lightsaber to Palpatine] His lightsaber.

Palpatine:
Ah, yes, a Jedi's weapon, much like your father's. By now you must know that your father can never be turned from the dark side. So will it be with you.

Luke:
You're wrong. Soon I'll be dead, and you with me.

Palpatine:
[laughing] Perhaps you refer to the imminent attack of your Rebel fleet? Yes; I assure you, we are quite safe from your friends here.

Luke:
Your overconfidence is your weakness.

Palpatine:
[looks back at Luke] Your faith in your friends is yours.

Vader:
It is pointless to resist, my son.

Palpatine:
Everything that has transpired has done so, according to my design. Your friends, out there on the sanctuary moon, are walking into a trap, as is your Rebel fleet. It was I who allowed the Alliance to know the location of the shield generator. It is quite safe from your pitiful little band. An entire legion of my best troops awaits them. [mockingly] Oh, I'm afraid the deflector shield will be quite operational when your friends arrive.
