Roderick wrote that he felt physically and emotionally ill, so the Visitor helps him quickly. The Visitor mentions that the Usher family, although an old clan, never thrived. Since her arrival, she has observed the family's isolationist tendencies, as well as the mysterious and special connection between Madeline (Roderick's twin sister) and Roderick. Through history and its various states of consciousness, Madeline ignores the narrator's presence. After Roderick Usher claims Madeline is dead, he helps her put it in the underground vault, although she has noticed Madeline's red appearance.
