4. The watcher.

The one who watched was quiet. In his own mind he was inseperable from the tide of people on the bridge, from any of them or all of them. For that matter he was no different from the bridge itself, or the river, or the air that moved invisibly over all of these. He could feel every footstep as he made it and as though those footsteps were upon him. He could actually feel these things in his own feet and upon his spine and within his body.
