In this chapter, the narrator tries to cheer up his sister, who is in a panic. He tries to reassure her that she will be able to handle the situation. He tells her that he will be her tutor, and that she should not worry about what he will say to her. He also tells her to ask him questions if she is having trouble understanding something. This is the part he doesn't understand, and he asks him to help him with it. He then asks him if he has trouble understanding anything, and if he's having trouble answering a question, he should ask him. The narrator then tells him to rub his legs as if he is rubbing someone else's. He says that his legs are just like his sister's and that his sense of guilt is turning him on.
