But Batty is seen working his way towards the roof. Deckard gets up on his feet, scanning around he sees a possible exit and heads for it.
Suddenly Batty pops out from that exit, Deckard stops in his tracks, does an about face and starts running.
With no hesitation, he makes a desperate leap to the next building. Flying in mid-air, his hands just barely grasp onto the roof cornice.
EXT. THE SECOND ROOF: Deckard hangs onto the cornice in the wind and rain. One hand is almost useless, the other's strained to the limit. He looks down. A long, long fall to the ground.
Deckard looks behind him, over his shoulder. He can see Batty twenty feet away on the edge of the first roof, watching him. Deckard is almost sobbing, holding on with everything he's got.
CUT TO EXT. THE FIRST ROOF: Batty stands facing away from Deckard as if in deep thought. He's holding a white dove in one hand and still has the large nail in his other hand. Batty turns toward Deckard, sprints quickly, and leaps.
CUT TO EXT. ROOF - LOW ANGLE: From below we see the tiny figure of Batty as he leaps easily across the gap between the two looming skyscrapers.
CUT TO EXT. SECOND ROOF: Deckard is hanging there as Batty lands not far from Deckard's desperate hands. The street looms way below. Deckard's bad hand is losing it's hold.
Batty looks down at Deckard.
BATTY: Quite an experience to live in fear, isn't it. That's what it is to be a slave.
Deckard's bad hand gives away, his other hand barely hangs on but it too is slipping, his last chance from dropping several stories to his death. Batty is still looking at Deckard intensely. This is it, Deckard has nothing left physically to hold on, his hand slips off the cornice.
Then in an instant, Batty's hand is like lightning. He catches Deckard's hand and holds him dangling over the edge.
Deckard is suspended above the awesome drop, not sure why he's not falling. Deckard hangs there and for a moment he has to consider whether this is the continuation of a cruel game. Batty is hauling him up one-handed with that scary strength he has.
Deckard is pulled onto the roof where he lies there gasping for breath, not moving, just feeling something solid under him.
Deckard is looking at Batty not sure what he's going to do next. Batty sits close to Deckard crossing his legs. He looks back at Deckard with eyes full of life and intensity. They stare at each other for a moment in silence, communicating something with their eyes... without expression. Finally Batty breaks the silence.
BATTY: I've . . . seen things you people wouldn't believe. . . Attack ships on fire off the shoulder of Orion. . . I watched c-beams glitter in the dark near the Tanhauser Gate. . . All those moments. . . will be lost in time. . . like. . . tears. . . in the rain. . . . Time to die.
Batty holds Deckard's eyes like a hypnotist.
It's lighter now and Batty's head slumps down, eternal sleep.
Batty doesn't stir. Deckard is watching motionless.
EXT. ROOF - DAWN: The white dove takes flight. It flies upwards towards the grayness of the buildings and the clouds.
