In the tribunal chamber, Santángel feels fate shift and realizes Luzia’s accusation has turned him into the perfect scapegoat. He tells Víctor de Paredes that he is confessing so Luzia can live, arguing that once Santángel is executed, Víctor will lose his leverage over her and the bargain Santángel made with Tello will no longer help Víctor ensnare Luzia.

Questioned by Don Pedro, Santángel formally admits to demonic possession and witchcraft, accepting that there is no recantation and that execution will follow. Asked whether the Ordoños or Víctor knew, Santángel chooses not to implicate Víctor, insisting they were deceived, because he fears the court would dismiss him as mad and shift blame back onto Luzia to protect Víctor’s reputation.

As the warden prepares to take Santángel away, Víctor tries to assert control, reminding Santángel of their bond and attempting to shape the court’s perception of Luzia. The judges press Víctor about making Luzia part of his household after her public punishment, and Víctor agrees, accepting responsibility for her “spiritual well-being” so she will not be “led into such delusion again.”

Unexpectedly, Fortún Donadei, the Prince of Olives, is brought in with Doña Beatriz. Donadei claims he saw Santángel and Luzia as lovers and says Valentina Ordoño even offered Luzia to him, then pivots to protect Víctor by portraying Víctor as sincerely deceived and blaming Santángel and Luzia for conspiracy.

Pressed further, Donadei adds that he saw Luzia whispering with Antonio Pérez and the heretic Teoda Halcón, shifting the danger back onto Luzia. Instead of denying it, Luzia openly embraces the accusation and adds vicious blasphemies, horrifying the room. Guards seize Luzia; the warden leads Santángel away. Víctor vows to watch them burn, and Santángel answers with bitter defiance, leaving Víctor with a final, cutting wish of “good luck.”
