During the carnival in Italy, Montresor runs into Fortunato, and offers him a nice bottle of wine. However, this bottle is in the catacombs. It is to late and Fortunato seems ill.
Montresor told Fortunato that he doesn't think he should go down there because he was busy and he has a cold. He tells Fortunato it is wet because of the "nitre" growing on the walls.
Fortunato starts coughing bad and Montresor gives him wine to make the cough go away. When they get close to the catacombs Fortunato asks for more wine. Fortunato drinks it all in one crazy big gulp.
