Montesor traps Fortunato
Montesor, pal, what is going on?
Since Fortunto is a very foolish human being, I took him to my wine cellar where he was so excited to see a bottle of Amontillado. Now that I, Montesor, have Fortunado in my grasp, I will make sure he pays for disrespecting me and my family name.
There are some fine grade wines down there
Fortunato is a fool. The man really thought I was going to give him Amontillado, the fool. Since Montesor acted so nice fortunato assumed he would have been given free wine. Now that Fortunato is trapped down here, Montesor can make sure no one threatens his family name which is very good.
