Though decidedly shaken by the fall from the tower upon him, Roderigo defied the old gentleman and refused to stir.

This dauntless example fired Zara.

She also defied her sire, and he ordered them both to the deepest dungeons of the castle.

A stout little retainer came in with chains and led them away, looking very much frightened and evidently forgetting the speech he ought to have made.
Act third was the castle hall, and here Hagar appeared, having come to free the lovers and finish Hugo.

She hears him coming and hides, sees him put the potions into two cups of wine and bid the timid little servant, "Bear them to the captives in their cells, and tell them I shall come anon." The servant takes Hugo aside to tell him something, and Hagar changes the cups for two others which are harmless.
Ferdinando, the 'minion', carries them away, and Hagar puts back the cup which holds the poison meant for Roderigo.
