In this chapter, we learn that the teacher has been sleeping soundly for ten years, during which time his son has grown up to be a successful businessman. He has earned enough money to pay the teacher's medical bills, and he has also become very close to his family. He tells the family that the world is still fighting over the equipment, but that it will not last long. The teacher apologizes for making the compromise, but he blames himself for the whole situation. He says that he has been holding back his whole life, both his family and his students, all have died in the war, and now he has to catch up with the rest of the world and destroy the equipment. The old man says he will support everything the teacher is doing, and that he believes that the old man has not betrayed humanity
