prisoner #1 rises. through caging:
young guard wrestles gun from prisoner #2 and fires, killing prisoner #2. copeland grapples with wounded young guard.
old guard reloads. copeland drops down behind a seat.
engine dies. dusty silence. we don't know up from down.
kimble sees: old guard fights the cage door. kimble lunges to his side.
kimble spots keys. pitches them to old guard. drags young guard to the front for a quick exit. but old guard fumbles the key-ring, his hands shaking as much as the bus.
train light grows. a nanosecond of uncertainty: should kimble leave the wounded man? kimble and the young guard hold a look.
