Lets go down to the catacomb and get some Amontillado!
Cough, cough, cough
Fortunato and Montresor first met at a carnival. When they first met, Fortunato is very drunk and Montersor realizes that this is the perfect time to put his plan in action.
Here, have some more!
At this time, Montresor takes the first step in his plan. He wants to take Fortunato down to the catacombs and get Amontillado. He is really just saying this to get Fortunato
While in the catacombs, Fortunato keeps coughing and Montresor suggests that they go back. However, he just says this to make Fortunato want to keep going.
At this point, Montresor is trying to get Fortunato to get very drunk. Fortunato had already been drinking all night so he gave him wine too just to be sure that he wouldn't sober up.
This is when Fortunato still doesn't understand whats going on and he thinks that it's just a joke.
When Montresor is leaving, he chains up Fortunato and puts rocks in front of the passage way so he can't get out. At this point Fortunato figures out what's going on and doesn't want Montresor to leave him.
