Sam’s fingers flashed over the keys of his cyberterminal. The flow-through program disengaged and he activated the program he had named Tag Along. When the terminal brought Tag Along to active status, his icon flashed opaque, resolving into the standard Raku salaryman icon. Sam stood and placed himself behind the Jiro icon, pacing the intruder step for step and turn for turn. Occasionally, Sam’s icon flickered suddenly to a new location, "teleporting" with the power of Tag Along to remain out of the Jiro icon’s line-of-sight and thereby out of the operator’s awareness.
