Hannah moves fast through the city street, past storefronts and blurred faces. She rounds a turn — SMACK. She collides full-force with someone. A firm grip catches her shoulders: WILL. But this Will doesn't know her — he's startled. She calls him by name. An awkward exchange: he insists they've never met. She runs off. He calls after her: "Don't make me come find you!"
City park. Hannah storms away from the café terrace, hands clenched, breathing hard. Will calls her name (O.S.). She ignores him, quickens pace. He catches up, grabs her shoulder. She whirls around — "Don't touch me!" They argue: she says he lied about fixing things, he says they need to go further back. She's furious and desperate. "I WANT TO GO HOME!" THE HUM builds.
Morning after. Will walks a street alone. GRAHAM leans against a wall, confronts him — "You were there." They argue about changing the past. Graham warns it's dangerous. Will walks away angry.
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.
City park. HANNAH at the spot where she first met Josh. WILL arrives. Josh is somewhere nearby. Three characters but the focus is Will and Hannah — their alliance is fracturing.
