At last BILLY's expression changes to almost childish relief, for here at last is the refuge he seeks; the relative comfort and silence of THE WHEEL.
It is a grim, squat PILLAR dominating the room and bearing the weight of the ceiling. And around it some SIXTY LUNATICS trudge slowly, near silently, in counter-clockwise flow. It is a hypnotic shuffle and BILLY blends right in, sliding easily into the sluggish, mindless river, his eyes hanging loosely on the floor, watching:
THE SOOTHING RHYTHM OF FEET shuffling at a comforting pace.
These are the spokes of the wheel.
