As "Eddie" goes to meet Ava, "Philly" is looked after the bodyguard Boogaard, but with her charms she makes him approach and punches him unconscious. Miho emerges from the compartment and then the two throw to the guards a bag of explosives. This gives Dwight the diversion to shoot Manute and finally Ava.
