Edward Hoyt warns Wayne in 1990 that he has evidence connecting the detectives to Harris James's disappearance. Wayne leaves policing afterward and builds another working life alongside Amelia. Earlier scenes return to the argument over her criticism of the original investigation and the choice to marry despite their difficulties. Their marriage remains central to the memories through which Wayne approaches the case in old age.
Wayne and Roland find Junius Watts, who explains his role in arranging meetings between Julie and Isabel Hoyt. According to Watts, Isabel tried to take Julie, pushed Will when he intervened and caused his fatal fall. Payments silenced Lucy, and Julie was kept in the pink room until Watts later helped her escape. A convent account says she eventually died, apparently ending the search, but Wayne notices a connection between its groundskeeper and Julie's childhood friend Mike Ardoin.
Prompted by Amelia's book and an imagined conversation with her, Wayne follows that connection to a family home. A lapse leaves him unable to explain why he has arrived, and the woman there gives him water while he waits for Henry. The family offers a possible answer to Julie's fate, but Wayne's expression does not establish exactly what he understands or remembers. Henry keeps the address. Wayne returns to his own family, with Roland beside them, as the ending moves through his memories of Amelia and his younger self in Vietnam.
