Amelia crashes into a darkened room in 1965 Boston, disoriented and expecting to find Anton and Uncle Ernest. Ernest appears and, though confused by Amelia’s late-night intrusion and oversized coat, treats her gently and sends her back to bed with tea. Amelia notices Ernest wearing the familiar watch and realizes something fundamental about her life may have changed.

That night, Ernest returns to bed with his wife, Lisavet, and their conversation reveals a new reality: Amelia is their daughter, and Ernest considers himself Amelia’s father. Through Ernest’s recollection, Amelia’s parents’ history is recast—Lisavet’s family came to Boston before the war, Lisavet became a watchmaker, and Ernest stayed in the family watch business instead of a government career.

By morning, Amelia’s mind “fills in” as she observes her memories like a spectator, gaining knowledge of this altered life alongside the old one. She finds a home with present, loving parents, a different school situation, and a world no longer shaped by the same time-space interventions. In the garden, Lisavet’s accent and a late-blooming patch of forget-me-nots prompt Amelia to question whether any of this is real; Lisavet answers with gentle acceptance, suggesting that even a memory can matter if it is happy.

Driven by the pocket watch and the need for certainty, Amelia tries to reopen the time space and initially fails. Concentrating harder, she finds a threshold and steps into something transformed: not the former quiet library-like space, but a boundless, star-filled expanse of swirling, intersecting memories—loud with whispers, fluid, and unconstrained by fixed history. Understanding that Time persists but in a freer, less controlled form, Amelia returns and chooses to close the door for good, never opening it again.

In her new daily life at a local private school, Amelia witnesses bullying and learns a Russian exchange student is being targeted. She recognizes him as Anton Stepanov, now living a different version of himself, and intervenes by helping him collect his books. Over lunches and sharp banter, Amelia repeatedly seeks him out; a trade of desserts becomes a small ritual, and Anton finally offers her chocolate “no country… just friends,” marking the start of their friendship in this altered world.
