What will Dr Sadao do to get rid of the man?

Explanation

With the injured American's health gradually improving, Dr Sadao and Hana were in a fix as to what should be done with him.However, finally Dr.Sadao will succeed to get rid of him.Their loyal servants had left them.Keeping him in their house could pose a threat to their lives as well. As Hana’s impatience and distress grew, Dr Sadao revealed the matter to the General who decided to send assassins to kill the young American in his sleep. Keen on getting rid of the escaped war- prisoner, Dr Sadao agreed. However, the matter could not be resolved because the assassins never came.
Dr Sadao then planned another way to get rid of him which was overpowered with sympathy and a distant gratitude towards the people he had been linked to in America. He decided to save his patient one more time. He secretly sent him to an isolated island with food, bottled water, clothes, blanket and his own flashlight on a boat from where he boarded a Korean ship to freedom and safety.
