"At the request of Usher, I personally aided him in the arrangements for the temporary entombment...The vault in which we placed it(and which had been so long unopened that our torches, half smothered in its oppressive atmosphere, gave us little opportunity for investigation) was small, damp, and entirely without means of admission for light;" CM: The narrator helps Usher bury the tomb which was a decision he doubted very much and he was very uneasy about. This foreshadows the events that occur later in the story which prove his suspicions correct.
"But, as I placed my hand upon his shoulder, there came a strong shudder his whole person: a sickly smile quivered about his lips; and I saw that he spoke in a low hurried, and gibbering murmur, as if unconscious of my presence. Bending closely over him I at length drank in the hideous import of his words"(29). CM: The narrator reads the Mad Trist to Usher and shortly after finishing the story, Usher's mind starts to deteriorate as he goes insane.
"There was blood upon her white robes, and the evidence of some bitter struggle upon every portion of her emaciated frame... then, with a low moaning cry, fell heavily inward upon her brother, and in her violent and now final death agonies, bore him to the floor a corpse, and a victim to the terrors he had anticipated...my brain reeled as I saw the mighty walls rushing asunder"(30). CM: After the narrators suspicions came true, Ushers sister turned out to be alive as she dies on top of her brother and the House of Usher falls metaphorically and literally as the narrator flees on his horse.
