This is what he sent me:
"I have read part of a top secret copy of the Episode III screenplay. In it, Anakin falls into a lava pit while fighting Obi-Wan (lightsaber battle). The Emperor rescues him in the form of 5 monks, and gives him the suit if he promises to serve him. Anakin says he will only if he can see Amidala for one last time. The Emperor conjures up a fake image of the Jedi killing Amidala. Anakin becomes so angry he destroys the holo cube with his lightsaber and becomes Darth Vader.
At the very end, Obi-Wan leaves Luke with his brother Owen, and walks off into the deserts of Tatooine."
