Montresor tells Fortunato that the motto of his family coat of arms is "No one injures me with impunity." Fortunato is drunk and attaches no particular significance to this information. Then Montresor tells him he is a Mason and shows him a trowel he had been concealing under his cloak. Fortunato reacts with surprise and some slight alarm, but he is too intoxicated to give it much thought, and he is anxious to get to that cask of Amontillado. Montresor keeps pointing to the walls of the catacombs which are covered with nitre, warning Fortunato that it is an unwholesome atmosphere and advising him to turn back in order to protect his health. But Fortunato is so intent on getting to the Amontillado that he ignores Montresor's advice and warnings, even though he already has a bad cold and is continually coughing. Another hint might be discerned in the fact that Montresor has repeatedly told Fortunato that the wine he bought may not be genuine Amontillado after all. When Fortunato says, "I shall not die of a cold," and Montresor replies, "Very true. Very true," Fortunato might have taken this as a warning if he had been sober. Poe is also indicating to the reader that Fortunato will not die immediately but will suffer a long, lingering, agonizing death.
