A mysterious FBI agent keeps tailing Light, and Light's solution is to treat it like a contract mission with a tidy briefing. He does not know the guy's name, so he needs to see his ID without raising suspicion. The most normal thing for a student to do is to take a pretty girl on a date, board a bus and stage a hijacking. Obviously. The Cover Story: Light invites a girl from his school to go on a day trip and just happens to head for the same bus the agent will follow. Raye Penber is stuck pretending to be a regular passenger. Light uses a date as a prop like it's a cardboard cutout. The Pre-Written Hijacking: A man with a weapon storms the bus at the right moment, because Light wrote his name and actions in the notebook. Passengers scream, the driver freezes and the criminal acts exactly as scripted. Light is basically the game's invisible director. The Badge Trap: Light stays calm and puts Raye in a spot where the only way to help is to flash his FBI badge. Raye shows it to the hijacker, and Light reads the name on it. Penber shows his credentials to a high schooler in the middle of an emergency. The Ghost In The Back: The hijacker suddenly looks to the back seats and screams at something no one else can see, because Ryuk is standing there. He empties his gun, bolts off the bus and gets hit by a car exactly as planned. The dead-end of the plot is neat, and Raye stays on the bus with shaking hands. TL;DR: Light used a date, a scripted hijacker and a badge to pull the name of an FBI agent out of thin air. The meta shifts from hiding in the dark to hunting the hunter, and Raye is now visible on Kira's list without knowing it. Contract complete.
