Will exits Maya's building carrying the giant Hugzilla, which blocks his sightline. A cyclist — GRAHAM — slams into him. Will falls. Graham hits the pavement, blood at his hairline. Will tries to help; Graham coughs, bleeds.
Evening. Will and Graham walk a sodium-lit street, shutters half-down, shop lights dying. Graham grabs Will's arm and rewinds time — they're on the same street, earlier. Graham explains the rules of travel: can't go before birth or after death, always end up wherever your body was.
Street. Will walks away from the café. GRAHAM intercepts him — says Will has changed something. Graham is furious, grabs Will's wrist. "This isn't a game."
Outside Maya's building. WILL orchestrates GRAHAM's bike crash — causes it intentionally this time. Graham hits the ground. MAYA is visible from an upstairs window, looking down. Will is manipulating events.
Classroom/lecture room. GRAHAM draws his time-loop diagram on the whiteboard — five circles rolling into one large loop. HANNAH and JULIA watch and listen. A tutorial in time travel mechanics.
