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.
Quieter bedroom with coats on the bed. Will opens a dresser drawer and finds a paperback with a photobooth strip as a bookmark — Hannah and Julia, cheek to cheek. JULIA enters and catches him. He's embarrassed; she's curious.
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.
Josh and Julia's house, evening. JULIA walks in, drops keys. JOSH appears — mirror shot of 1.06. "Who are you?" He doesn't recognise her. Julia tries to explain she was out with Hannah. Josh is a stranger to her in this timeline. HANNAH is present, having brought Julia here.
Josh's house hallway. JOSH backs away from JULIA. "Do you need help?" Julia pleads — tries to make him remember. He doesn't know her. HANNAH watches the confrontation.
Josh and Julia's house. JULIA pleads with JOSH alone — "I'm your girlfriend." Josh is bewildered and cold. Hannah has left. Two-hander, raw and desperate.
Neighbourhood café. HANNAH, JULIA and GRAHAM meet. "Lost in time." They discuss the situation — three Travellers trying to understand what Will has done.
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.
