Plot summary
Under the influence of the "B" pill, Annie and Owen then transition into a shared fantasy where they are Arlie and Ollie, two con artist magicians in the 1940s invited to a séance at an exclusive house party. They have an ulterior motive: to find the long lost 53rd chapter of Cervantes ' Don Quixote, believed to possess the power to hold people in their fantasies for an eternity. The séance, led by a humanized GRTA computer, provides a distraction for the two to search the house. All the while, Arlie's character has been randomly "zapping" out of the fantasy and into the NPB lab, where she sees visions of the real Annie's past.
Back at the NPB lab, Azumi begins to notice the inconsistencies between subjects 1 and 9, realizing their unusual connection under the influence of the drugs. Annie is subsequently taken into questioning by James about her experiences with the "B" pill to see if she should continue her participation in the trial, while Owen and the rest of the subjects wake up from their tests.
