ANAKIN follows, and OBI-WAN cuts his young apprentice at the knees, then cuts off his left arm in the blink of an eye. ANAKIN tumbles down the embankment and rolls to a stop near the edge of the lava.
ANAKIN struggles to pull himself up the embankment with his mechanical hand. His thin leather glove has been burned off. He keeps sliding down in the black sand.
OBI-WAN: (continuing) . . . You were the Chosen One! It was said that you would destroy the Sith, not join them. It was you who would bring balance to the Force, not leave it in Darkness.
OBI-WAN picks up Anakin's light saber and begins to walk away. He stops and looks back.
ANAKIN: I hate you!
OBI-WAN: You were my brother, Anakin. I loved you.
ANAKIN'S clothing blows into the lava river and ignites. Suddenly ANAKIN bursts into flames and starts SCREAMING.
