Psycho-Pass S02E02 - The Creeping Unknown

While trying to determine the meaning of the "WC?" message, Akane goes with Enforcer Sakuya Togane to interrogate Kitazawa, who claims that someone else helped keep his crime coefficient down and was responsible for the fake hostage, though another inspector, Aoyanagi, does not believe this to be true. Later, as Shion and Enforcer Sho Hinakawa learn that the fake hostage was an elaborately detailed hologram modeled after someone who died years ago, Kitazawa's crime-coefficient suddenly drops below that of a latent criminal, resulting in him being transferred to a general medical facility. Shortly afterwards, Akane discovers another "WC?" message scrawled in her apartment, before being alerted that Kitazawa had attacked Aoyanagi and escaped, believing that his claimed assistant was the one who set up his escape route. Kitazawa is cornered by Akane's group, uttering the name "Kamui" before he is eliminated by Aoyanagi, his last words leading Akane to realize that "WC?" actually stands for "What Color?".
