Montressor and Fortonato get down to the end of the catacombs. Once there, Montressor forces Fortonato into a small hole in the wall, chaining him to a board. He moves over to a pile of bones and moves them saying he is getting the amontillado, but he is not.
With Fortonato being tied up, he soon passes out from being so drunk. When he comes to, Montressor is building a wall in front of him, making him part of the catacombs. Thinking it is a joke Fortonato laughs and tells him to stop this nonsense.
Once Montressor doesnt hear anymore sound, he looks into the hole, noticing Fortonato has passed out/died. He then finishes the wall and moves the bones in front of the wall, making them look undisturbed. He then leaves going back out of the catacombs like nothing happened.
