Answer:
Fortunato hurts Montessor 1000 times, then insults him.
Montessori wants Revenge for the insult, and he wants it to be permanent.
He meets Fortunato and Lois him into the montessor family catacomb.
Plying him with wine, and the promise of rare Amontillado, Montresor leads Fortunado deeper and deeper into the underground graveyard.
Eventually, Fortunato walks into a man-sized hole in the wall of one of the crypts.
