Carlos has awakened from his former madness; devoted only to the accomplishment of his friend's dying request, he disclaims the entertainment of any other feelings for the queen than an affection founded on the circumstance that she was the confidant and friend of the Marquis. At this juncture the King, Grand Inquisitor, and Nobles appear in the back-ground, unperceived by the Prince or Elizabeth. _Carlos_. Now I depart from Spain, And see my father in this life no more; I cannot love him—nature in my breast Is now extinct—be you again his wife; His son is lost to him. Return to duty. I go to rescue my oppressed people From tyrant hands. Madrid sees me as king, Or never more. Now for our last farewell! * * * Did you hear nought? _Queen_. No, nothing—save the clock That sounds our separation. _Carlos_. Then good night, Mother; from Ghent you will receive the letter Which shall the secret of this interview Make public. I depart—henceforth with Philip To walk an open path. Henceforth between us There's nothing secret. You shall never need To shun the world's eyes. This is my last deceit. (_Attempts to put on his mask—the king steps between them_.) _King_. It is your last! (_Queen falls senseless_.) _Carlos_. (_catches her in his arms_.) Is she dead? Oh, heaven and earth! _King_. Cardinal! I have done My part—do yours!
