Let us say that Montresor is a mistress of Fortunado. He insults her in front of another man, couple, or lover publicly; as it is never said what the insult is specifically. Upon this insult Montresor, our female character, is so enraged with adrenaline and emotion that she plots a plan to show Fortunado that she is a force to be reckoned with. While the adrenaline pulses through her veins she disassembles the wall with ease and preps it for the demise of the unsuspecting enemy.
As most have heard or witnessed in everyday life, powerful surges of adrenaline can cause people to do tasks they normally would have no strength to accomplish. As she lures our ironically unfortunate Fortunado through the musty, damp tunnel of underground, she taunts him. Or could this be her feminine compassion coming to the surface of the reality that is to be Fortunados fate? As she continues to suggest turning around on the journey, she comforts him and his cold as though she could be having second thoughts.
Montresor has a compassionate heart and conscious. A man would rarely show these traits. Finally, she has him right where she wants the insulting character. The taste of revenge returns. She remembers why she has brought our victim to his bone chilling demise. She replays the time or countless times that Fortunado has insulted her publicly and she shows him what he deserves. Bone by bone, she finds pleasurable satisfaction in her plan. As the saying goes, Hell hath no fury like a woman scorned.
