Bridge Spanning the Original Battlefield - S1.E9

During spring break from school, Wil meets Allison and Fiona on a luxury train which runs between the eastern and western countries. Halfway over the Lutoni River, the train stops for a flower tribute in observance of the war victims, and Wil tells Fiona how Allison's father was killed by his own subordinate since it would have been dangerous having him caught as a prisoner of war due to him likely being in the intelligence division of the military. The train makes another stop on Green Island and picks up Ker who is in disguise, and a Major with the Sou Beil military on assignment.
