Agnes' final remark to Ambrosio as the Prioress is dragging her away is an example of foreshadowing. Ambrosio was Agnes' last chance for mercy; he could have decided not to show the letter to the Prioress, and instead allowed Agnes to escape with her child and reunite with her beloved Raymond. She screams out at him: "Man of a hard heart! Hear me, proud, stern, and cruel! You could have saved me; you could have restored me to happiness and virtue, but would not! [...] Insolent in your yet-unshakeable virtue, you disdained the prayers of a penitent; but God will show mercy, though you show none. And where is the merit of your boasted virtue? What temptations have you vanquished? Coward! You have fled from it, not opposed seduction. But the day of trail will arrive! Oh! Then when you yield to impetuous passions! When you feel that man is weak, and born to err; when shuddering you look back upon your crimes, and solicit with terror the mercy of your God, oh! aIn that fearful moment, think upon me! Think upon your cruelty! Think upon Agnes, and despair of pardon!" (Pg. 48.)
Ambrosio is deeply shaken by these words, which foreshadow his seduction by Matilda, a beautiful woman who has disguised herself as a monk. Eventually, the two break their vows of chastity, leading to consequences far more terrible than those faced by Agnes.
