who was meant to be attending her, the Countess of Aremberg, to return to France, prompting Elizabeth to sing a sorrowful farewell-aria. (Aria: "Oh ma chère compagne" / "Non pianger, mia compagna"). The King now approaches Posa, with whose character and activism he is impressed, and offers to reward him for his loyalty and service. Posa begs the King to stop oppressing the people of Flanders. The King calls Posa's idealism unrealistic and warns that the Grand Inquisitor is watching him. The King confides in Posa, telling him that he fears that Carlos is having an affair with Elisabeth. Posa replies that Carlos is innocent, and offers to watch Elisabeth and to be responsible for her good behavior. The King gratefully accepts this offer, and again warns Posa to beware of the Grand Inquisitor.

Posa draws his dagger, intending to stab her to death, but reconsiders, spares her, and declares his trust in the Lord. Eboli exits in a vengeful rage. Posa
