The next morning, the doctor tells the gang that he has found a cure for the disease, but that it will take a long time before it is found. He tells them to take care of their sister, who has been saved for now. The doctor tells them that there are still many people in the city waiting for him to save them, and that he cannot fall ill. The gang tells the doctor to take a nap, but the doctor refuses, saying that it is not his fault that he was brought down. He blames himself for the suffering of the people.
