"I learned that the deceased and himself had been twins...The disease...had left...the mockery of a faint blush upon the bosom of the face, and that suspiciously lingering smile upon the lip..."(Poe 24). The narrator learns how Madeline and Usher were twins; while putting her lifeless corpse in the vault, he sees her cheeks still have a redness which was suspiciously strange to him.
"...there did stand the lofty and enshrouded figure of the lady Madeline of Usher. There was blood upon her white robes, and the evidence of some bitter stuggle upon every every portion of her emaciated frame"(Poe 30). Usher confesses that his sister was buried alive and in walks in Madeline angry and tries to attack her brother but they both end up dying, Usher because of fear of seeing his sister.
"I fled aghast...While I gazed, this fissure rapidly widened-there came a fierce breath of the whirlwind-my brain realed as I saw the mighty walls rushing asunder...the deep and dank tarn at my feet closed sullenly and silently over the fragments of the 'House of Usher' " (Poe 30). After witnessing these deaths, the narrator flees from the mansion in fear for his life as well as he sees the house crumbling to the ground.
