How did Dr. Sadao ensure that the American sailor left his house but he himself remained safe and secure?
Dr. Sadao helped him by giving him a boat, rations, Japanese cloths and even a torch light with which he could indicate in case his supplies ran out or if he did not find a Korean fishing boat to rescue him from the Island where he was to seek refuge. Sadao had made sure that he was strong enough to take this chance and save his life.
Did Hana think the Japanese tortured their prisoners of war? Why?
Yes, she thought that the Japanese tortured their prisoners of war as she saw deep red scars on the neck of the wounded American soldier while washing him. The scars right under the ears spoke of the extreme torture afflicted upon the prisoners of war.
The distress of his wife at the sight of the operation and his inability to go to her at once forced Dr. Sadao to be impatient and irritable with his patient who lay like a dead under his knife.
