Annoyed at Arnies skepticism, David quiets him by recounting Arnies last dream and continues his story from the beginning. When David and Fred Chu attend a concert by John and his band, they witness Amy Sullivan being teased for being an amputee and missing an arm by wannabegangsta Justin White. Amys dog Bark Lee has gone missing after biting Robert Marley, a Jamaican drug dealer, who, despite Davids skepticism, displays psychic powers. David then finds and cares for Bark Lee. That night, David receives a frantic call from John, who seems paranoid and delusional. David recovers a syringe and tries to take John to the hospital John refuses and describes buying a drug from Marley. John claims the drug, called soy sauce, gives him a nonlinear perception of time and the ability to perceive alternate dimensions. David doesnt believe him until he receives a call from John on his phone, despite Johns being there in person.As they drive off, John falls unconscious, and David is accidentally pricked by the syringe, which causes severe hallucinations, including an interdimensional traveler, Roger North. North attaches a giant leech to David, but before North can explain himself, David causes him to disappear when he kills the leech. Immediately afterward, Detective Lawrence Appleton takes them to the police station, where they are interrogated separately, and David realizes that he can predict Appletons questions. Appleton reveals that John is the only known survivor of a drug party that includes White and, after being called out of the room, tells David that John has died. At this point, Arnie interrupts the story and again expresses skepticism, but David convinces him by demonstrating a caged monster visible only from a certain perspective. ........
