I believe the scene where Montresor describes his hatred for Fortunato is the exposition. It shows us slightly what to expect from this man as the story progresses. Also I believe this is one of the few times in the story where we see just how mad he can get, and I don't mean anger mad, I mean crazy. He is literally saying that because Fortunato insulted him, he is justified in killing Fortunato and shouldn't be punished.
The next scene I chose is where Montresor manipulates Fortunato into joining him down into the catacombs. I feel this is an important part to the rising action because we get to see just how amazingly cunning Montresor is. He doesn't allow his anger at Fortunato to blind him into making mistakes and getting caught. He makes sure that his head is clear and comes in with a plan that he manages to pull off through smiles and drunkenness.
This scene is also an example of how cunning he is because he manages to use Fortunato's own stubbornness against him. In the story he tries to get Fortunato to go back because he is ill but Fortunato refuses convinced that he, "shall not die of a cough."(Poe, 36). But Montresor's brains are not the only thing that's great about this scene, it is the foreshadowing and suspense this scene created. In the end Fortunato ironically did technically die of a cough and the fact that they walk for so long just keeps the reader on the edge of their seat, waiting to see what will happen.
I believe that this is the climax off the story, the moment where Montresor chains up Fortunato to the wall. I believe that this is the climax because it is the moment we have all been waiting for, to finally see what Montresor has been planning this whole time. This is where you see that Fortunato finally understands his mistake and the grave danger that he is in. Where we finally see how far Montresor is willing to go.
I believe the scene where Montresor begins to cover up the path leading to Fortunato is a part of the falling action. I think this because the action is over, now it is just Montresor messing with Fortunato. You see even more how crazy he is, listening to Fortunato's cry's for help, Montresor even sat down to listen when he heard Fortunato rattling the chains. He even goes so far as to, "surpass[ed] them[Fortunato's cries] in volume and in strength"(Poe, 77) almost as if taunting Fortunato.
he! he! he!
I chose the scene where Montresor was finished with the wall as my resolution. I chose this because I believe that since Fortunato was wearing what we can assume was a jesters outfit, the sad and lonely jingles represent Montresor getting the last laugh. Or honestly it could be the other way around, I mean before he placed the last stone he claimed that "[his] heart grew sick"(Poe, 89) which could be a sign of guilt. It could mean that this event, these deeds he has done might come back to haunt him later inn his life always feeling guilt about what he had done, then it would be Fortunato getting the last laugh.
