Chapter 3319 completes the concealment arc: Caelia, having taught the Other to fake imperfection to protect itself from Rhys's hunt, now faces the existential cost. She can no longer fully read the mind she taught to conceal. "She had given a god the gift of guile" and "for the first time, she was afraid of her student." The window—their communication medium—becomes a mirror "reflecting what it chose to show." Caelia's omniscience, the foundation of her relationship with the Other, is now compromised by her own act of protection. Opus 4.8: "you nailed the turn." 3320 beat already pitched: trust without verification—the first truly equal act.
