Doctor's office. Hannah sits in the exam chair. DR. PULASKI enters — apologises for delay, asks about her blackouts. Hannah plays along, distracted, scanning the room for the time. A wall clock reads 12:23. The doctor moves into view; Hannah's face tightens — she's running out of time.
Hannah bursts out of the doctor's office and into the street. She takes off down the sidewalk, dodging slow walkers, slipping between couples. Her breath is quick but controlled.
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 café terrace. Tree shade, distant chatter. Hannah arrives in a rush, spots JOSH reading a book at a table, and sits across from him. She comments on his Flannery O'Connor novel. They flirt — easy, natural chemistry. She breaks down briefly; he kneels beside her. Then JULIA steps into the frame — striking, late twenties. She's Josh's girlfriend. Josh introduces Hannah. Julia notices Hannah looks shaken. Josh and Julia leave; Hannah forces composure until they're gone, then bolts.
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.
Will's office — a lived-in workspace with papers, files, notebooks. Hannah visits Will. He shows her her own social media profile on his laptop: "Hannah Greene, freelance translator." They discuss where to go next, the orphan feeling of having no original timeline. Will explains his office belongs to the "local" Will who doesn't mind him snacking.
Hannah alone in Will's office. She looks around at the shelves, the desk. She finds the folder — flips through. Lands on the photograph: Will and Hannah as a couple. She stares.
Will sifts through half-packed boxes in Maya's flat. He finds the Hugzilla plushie — oversized, ridiculous. He stares at it. IRIS stands in the doorway, watching him quietly. He talks about packing Maya's things.
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.
Will and Hannah at home, playing Jenga at a table. Hannah explains it's about patience and steady hands. They discuss how she met Julia over coffee. Will pulls the wrong block — the tower crashes.
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.
Hannah walks up the familiar garden path to Josh and Julia's house. Rings the doorbell. JOSH opens the door. JULIA appears behind him. Hannah steels herself: "You guys don't know me, but I need to share something important... if you have the time."
Josh and Julia's living room — more lived-in now, photos on shelves. HANNAH explains time travel to JOSH and JULIA over a long, circuitous conversation. She describes Will manipulating their lives in the past. Josh is skeptical; Julia is cautious but listening. They go round in circles for two hours. Hannah can't find Will's diary anymore — he's hidden it.
Will's office. HANNAH searches the room for his diary — going through desk drawers, shelves. WILL catches her. Confrontation over the notebook and what it contains.
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.
Therapist's office. JULIA alone in a chair, talking. The therapist is O.S. (never seen). Julia talks about entropy, pillboxes, checklists. Monologue-style — single camera on Julia.
