Sinker is the third episode of Vale Four and the conclusion of the Hooks Cycle. Hilton and Astoria arrive with opinions about everything that has happened so far and the energy of people who have seen this show before and cannot look away. Celeste and Vera finally tell someone about what is happening to them, and that someone routes them directly back into the loop. Tessa reaches her absolute worst, which in this series is a high bar. Z and Iris perform an infomercial for the system they are running, live to camera, with testimonials. The whole world is already singing, and Sinker is the episode where that stops being a metaphor.
