How? Amontillado? A pipe? Impossible! And in the middle of the carnival.
My dear Fortunato, you are luckily met. How remarkably well you are looking today. But I have recieved a pipe of what passes for Amontillado, and Ihave my doubts.
The cough is mere nothing; it shall not kill me. I shall not die of cough.
True, true. and, indeed, I had no intention of alarming you unnecessarily, but you should use all proper caution.
During this scene, verbal irony is used by Montresor being sarcastic about how Fortunato looks because he is drunk. He also tells him about a pipe and has his doubts.
Fortunato is saying that his cough will not kill him but Montresor is basically saying that he wants to kill him but he says that he had no intention on telling him about using precaution with where they are.
Montreso seizes Fortunato by the elbow and Fortnato thinks that he is going to do something because they passed skelentons, but instead Montreso suggest that they go back because of his cough.
