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.
Neighbourhood café. Will sits alone with the Hugzilla plushie in the opposite chair. GRAHAM walks in, pushes the plushie aside, sits down. He tells Will he remembers the crash — "it wasn't a dream." He was dying and transferred his consciousness into Will as a time traveller. They discuss the rules.
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."
FLASHBACK to the original park café meeting (same setting as 1.13). Tree shade dapples the terrace. HANNAH sits at a table. JOSH at another table, reading, smiling at her. WILL and GRAHAM watch from the trees at a distance. Graham confronts Will about creating chaos.
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.
