Northward, Turnabout Express - Last Trial

Phoenix discover that the train's cars were actually rearranged just before the takeover, and this leads him to deduce that the corpse from Car 1 was a fake and the real Gale was killed in Car 3 during dinnertime, suspecting of Turnbull. Edgeworth verifies Turnbull's involvement in the trial, having obtained the truth from the committee, and Turnbull reveals that he killed Gale when he attempted to blackmail him and was forced to create the fake scenario when the takeover occurred. After Richman is declared not guilty, he chooses to die alone by setting off a time bomb in the dining car, but the committee offers him a fair retrial, convincing him to safely join the others before the bomb goes off.
