The ending reveals that the glowing anomaly returns Denise and the children to shortly before Oak Street first vanished, rather than restoring them to the moment they left. This allows Denise to prevent Greg’s death and warn neighbours who died in the prehistoric timeline, creating a new future in which the street still disappears but most residents are safely elsewhere.

Two years later, the Platt family is reunited: Greg is alive, Denise has pursued her ambitions and is preparing to publish a book called *The End of Oak Street*. However, Greg has no memory of their survival experience or the conversations that repaired their marriage, leaving Denise with a happier but emotionally complicated version of the life she wanted.
