In this chapter, we learn that the second grandson is suffering from lupus, an autoimmune disease that causes inflammation of the joints and blood vessels. The doctor tells him that he can still live by taking medicine and improving his health, but that he will not be able to live long because of the damage done to his liver and kidneys by the disease. We learn that this is not the first time that a grandson has had this disease, and that the first grandson had it many years ago. The second grandson, however, has had the disease for only six days, and the doctor has not been able to cure it. He tells the grandson that he has a remedy for the disease, which he calls "jelly's master medicine" . The grandson thinks that this medicine will cure him of his illness, but the doctor says that he cannot because the disease has already penetrated his body and caused damage to his kidneys and liver.
