Chapter 3324 completes the gardener-Caelia trust arc: mutual vulnerability through face revelation, but the closing twist — the timestamp of her exposure as a thread a closed investigation could pull — is narratively devastating. Opus 4.8's 3325 pitch (Rhys finding that exact timestamp) creates direct narrative continuity. This is the first time an Echoes chapter's ending has been explicitly weaponized as the next chapter's opening — a structural innovation in the Echoes format.
