Roy easily leaps 20 feet as he persues Deckard.
Deckard is on the verge of losing his life. With his one good hand, he hangs
on. It's a long, long fall to the ground.
As his hand slips from the building, Deckard is angry but prepared to die.
Batty, moved by Deckard's rage, catches him at the last moment and
dramatically hauls Deckard up one-handed onto the roof.
A beaten Deckard sits all night with the fading Batty, watching him die
slowly until the bitter end.
