After Madeline's death, the narrator sees Usher becoming more and more withdrawn and more and more distant. Because he and Madeline were twins, he believes that a part of Usher died with her. Usher appears more and more confused and unable to communicate with the narrator. There is no question that Usher is having a mental breakdown, and the narrator is watching Roderick lose his mind as the story continues until the narrator leaves the mansion just before it all crashes down on the Ushers.
