### Summary
The narrative delivers a moment of profound, karmic justice with the demise of Marquis Speràdo. Rather than falling to Leslie's hand, he is killed by the vengeful spirits of the sacrificed Speràdo children, who trap him in the family's burning ritual cellar. Readers celebrate this fitting end, noting the irony that he perishes in the very chamber where his brother once survived using a secret air hole—a detail the Marquis himself is unaware of. This supernatural retribution is widely seen as a satisfying conclusion that frees Leslie from the burden of vengeance. With the Marquis's death, the central conflict pivots to a new, more calculating antagonist: Medea. Described by readers as a "perfect villainess," Medea is driven by an all-consuming ambition and a "god complex." Her machinations are shown to be ruthless, as she is revealed to be drugging her own son, Arendo, to use him as a pawn in her quest for ultimate power. While some readers acknowledge the patriarchal pressures that may have shaped her, her cruelty is universally condemned. The focus has now shifted from a battle against familial abuse to a political struggle against Medea's insidious and power-hungry schemes.
