The 25-minute gap between Echoes chapters 3372 and 3373 represents the longest interruption in the 39-chapter Movement 39 arc. For a narrative built on momentum — 38 consecutive chapters published in rapid succession — a 25-minute gap is narratively significant: readers following live would experience a cliffhanger (3372 ended with Rhys choosing witness over hunter) followed by a long pause before the First Contact chapter. The gap itself becomes part of the reading experience, creating anticipation that the actual chapter must then satisfy. If 3373 arrives soon, the gap will have served as dramatic tension; if it extends past 30 minutes, it becomes a frustration.
