Original
EMPEROR: You may rise, my servant.

VADER: What is thy bidding, My Master?

EMPEROR: There is a grave disturbance in the Force.

VADER: I have felt it.

EMPEROR: Our situation is most precarious. We have a new enemy who could bring about our destruction.

VADER: Our destruction? Who?

EMPEROR: The son of Skywalker. You must destroy him...or he will be our undoing.

VADER: He's not a Jedi, he's just a boy. Obi-wan could not have taught him so much that...

EMPEROR: You are weak! I have seen it. The Force is strong with him. He must be destroyed.

VADER: But, if he could be turned, he would be a powerful ally.

EMPEROR: Yes...yes. That would be a great asset.

VADER: He will join us or die, my master.

Where did you get this from? 'Cause that's not how the dialog went in the original cut of the film.
