This chapter opens with a flashback to the beginning of the novel, when the narrator explains that the girl in the picture has seen the layout of the two secret islands. He asks the girl if she has seen it, and the girl replies that she has. The narrator then tells the girl that he will bring her some midnight snacks, and that if she does not come back that night, he will leave her in the next room. The girl tells the narrator that she is afraid that she will be killed by someone in the room next to her, and she begs the girl to come back to the room where she is staying. She tells him that she was hungry and that she wants to buy her some food to eat. He tells her that she should go to the doctor if she is sick, and he tells her to go and see a doctor if her health is not good. He also tells her not to tell the girl about what has happened, because the girl will be afraid of being alone if she stays in the dormitory alone. The two girls agree that they should take action first, and then wait for the girl's health to improve.
