Ryback kills Penn, in a gruesome fight in the Kitchen. The Porter takes over the helicopter, as the train is still headed towards the Nevada Petrol Express. Ryback saves his niece, and meets Dane. Dane tells him it's too late to stop him, and that stopping him is impossible. Ryback shoots the laptop, and Grazer One's control is fully restored. The Government employs the self destruct sequence just as Casey and his niece escape the train. The hostages all survive. The ending shot shows Casey and his niece, at his relative's grave, paying tribute to his brother.
