Hannah reaches for milk in a grocery shop. She flinches at a car horn outside — her breath catches. At the checkout, a CASHIER scans her items mechanically. Hannah grabs her bag, rounds a corner, and slams straight into LILY. They recognise each other — Hannah wraps Lily in a desperate hug. Lily senses something is wrong.
Coffee shop. Hannah sits across from Lily, hands curled around a barely-touched coffee, grocery bag on the floor. She tells Lily she "died" — describes the crash and a man who saved her. Lily mentions Hannah's blackouts have been getting worse. Hannah doesn't know what blackouts Lily means. Lily gently suggests seeing a doctor. Hannah notices Lily's hair is different.
The door clicks shut behind Hannah. She steps into Josh's empty hallway — shoes padding on hardwood, the house eerily still. She moves toward the kitchen, grocery bag rustling.
Hannah sets the grocery bag on the kitchen counter and begins unpacking. Behind her, Josh speaks (O.S.): "Hello?" She freezes. Josh stands in the doorway, handsome but tense. "Who are you?" He doesn't recognise her. Hannah is devastated — tries to explain she's his girlfriend. Josh grows angry and orders her to leave. She bolts.
CAFÉ. A coffee cup clinks down. Hannah leans back, arms crossed. Will sits across from her. "You're a time traveller." He confirms it. He explains time travel using sugar on the table — pouring a straight line for the timeline, showing how consciousness jumps back. He produces a folder stuffed with handwritten notes, diagrams, photographs. He explains there are two versions of her: the 2018 Hannah whose body she's in, and her 2025 consciousness. He proposes a plan: go back to when she first met Josh at a park café and recreate the meeting.
