At the close of this appalling scene, Isabella enters in time to see the prince dragged away by the guards. The king pretends, as before, to attribute her emotion to fears for his own safety, and ironically tells her to be comforted by the assurance that all danger to the royal person is past; promising her that the traitor shall be visited with summary punishment. The villain who would shed the blood of a father, he suggests would not hesitate to take the life of a step-mother. After this cruel hypocrisy, he leaves her to despair, and she is joined by Gomez, who comes with offers of sympathy and assistance. He brings the sentence of Carlos from the council, who have adjudged him to death for an alleged attempt upon his father's life; and the sentence only wants the king's signature. Gomez artfully works upon her feelings; assures her that the prince's only fault is his right to the crown, which Philip would bestow upon one of her children. It is this, he says, that has caused the king's unnatural hostility to his son. The crafty minister affects the warmest pity for the unfortunate victim, and indignation for the cruelty of the monarch. The queen, deceived by these representations, implores his aid for the prince. Gomez answers that he will be too proud to accept safety at his hands, or save himself by flight; and Isabella offers to remove his scruples by a personal interview in the prison. The minister covers the joy he feels at this proposal by an appeal to the justice of heaven to protect the innocent. The fifth act opens with a soliloquy of Carlos in the dungeon. He wishes to die, but shrinks from the disgrace of an ignominious execution, and dreads above all that the king should discover his ill-fated attachment to the queen. The iron door opens, and Isabella appears; she beseeches him to save himself from impending death. Carlos, with a presentiment of despair, asks how she obtained access to his prison. He believes her to have come with the knowledge of Philip, and as a messenger of his vengeance. _Isabella_. Doth Philip know it? Heaven! Wo—if he did! _Carlos_. What say'st thou? Philip here Knows all. Who dares to break his stern command? _Isabella_. Gomez. _Carlos_. What do I hear? What fatal name, Fearful, detestable! _Isabella_. He is no foe Of yours—as you may think—— _Carlos_. If I could ever Believe he was my friend more shame would kindle My cheek than e'er did wrath. _Isabella_. Yet he alone Feels pity now for you. 'Twas he revealed The king's atrocious plot to me.
