The student was utilising a rare synergy of two special abilities: Acoustic Dampening, which allowed him to move without producing a single decibel of sound, and a Stealth ability. It was a combination designed for assassinations, deadly, silent, and invisible.

In the green-tinted world of Frame Recognition, the captain was as visible as a white neon sign in a dark alley. John watched, baffled, as the student suddenly slowed down and walked at a normal pace toward him.
