Reggie Davis admitted relief at being exposed and revealed his motive: to kill those responsible for his father’s death on a wartime troop train. He joined the FBI seeking justice, never expecting a chance at personal vengeance until he learned the true culprits were gathered by Anna Matheson on this train. Believing Anna had brought them to be killed, he decided to do it himself once he realized she had not.

Davis explained that Judd Dodge’s staged poisoning was obvious to him, so he confronted Judd in Car 13 and coerced Judd into following orders to help eliminate the others: Edith Doyle, Herb, Jack Lapsford, and Sally Lawrence, in any order. He confirmed that Judd killed Edith at Davis’s suggestion, using Anna’s drapery cord to frame Anna, and admitted to stealing Anna’s father’s pin in the observation car to further that frame. He also acknowledged slitting Herb’s throat and escaping through a window, which ruined his original blue shirt and forced a conspicuous shirt change.

Anna detailed the clues that exposed Davis: his changed shirt, the nature and location of his stab wound that indicated self-infliction rather than an attack by right-handed Judd, and inconsistencies in the supposed poisoning. Davis conceded he had stabbed himself on the left side to avoid vital organs, and that Anna’s stitches held because the injury was calculated.

Davis outlined his broader plan: have Judd secretly kill the witnesses, frame Anna so the blame would fall on Judd’s fake death, then ultimately kill Judd in a staged self-defense scenario, emerging as a hero. He noted Seamus’s real murder of Judd was outside his plan and that Seamus had not known his scheme. Despite the unraveling, Davis tried to recruit Anna, promising mutual vengeance—deaths for his targets and public ruin for Kenneth Wentworth, who was not on the train.

When Anna rejected him, Davis stated he would kill her. Anna produced Davis’s gun from his jacket pocket and pulled the trigger, but it was unloaded. She then warned that others knew the truth. As Davis processed this, Sally Lawrence struck him from behind with a champagne bottle, knocking him to the floor and into unconsciousness.
