Trevor stares into a mirror at home, repeating the words, "I know who you are." It is revealed that one year prior, a healthy looking Trevor ran over and killed a boy identical to Nicholas after taking his eyes off the road to use the car's cigarette lighter, which was witnessed by the boy's mother, identical to Maria. He decided to drive away, and the resulting guilt became the deep-seated cause of his insomnia, emaciation and repressed memory. Ivan was a figment of Trevor's imagination and a manifestation of himself before the accident. He fills the missing letters of the hangman note to spell "killer". He briefly considers going to the airport and escaping, but instead drives to police headquarters, signifying his "road to salvation", a recurring theme in the film. He is accompanied by a silent but encouraging Ivan, who bids him an approving farewell outside the station. At the police station's front desk, he confesses to the hit-and-run. Two police officers escort Trevor to a cell, where he states he wishes to sleep and does so for the first time in a year.
