How does Usher, Madeline, and the Narrator show love for each other in terms of loving each other and how they deal with deaths?
What binds Usher to Madeline, and what renders him terrified of her? If he conjures up her specter, arisen from the grave to bring him to his own, why does he do so? There is a clear incestuous undertone to the relationship between the brother and sister. Without spouses they live together in the great family home, each of them wasting away within the building's dark rooms. The Narrator describes the strange qualities of the Usher family--that it never has put forth "any enduring branch," that "the entire family lay in the direct line of descent." The implication is that incest is the norm for the Ushers, and that Roderick's and Madeline's strange illnesses may stem from their inbred genes.
