It is Imogene who arrives to offer hospitality to the shipwrecked strangers, but Gualtiero does not reveal himself. She tells her companion Adele that she dreamed that he had been killed by her husband. (Cavatina: "Lo sognai ferito, esangue" / "My duty is the compassion / that sends me to the aid of strangers"). From what Itulbo has told her about the pirate ship, she assumes that he is dead. When he comes out of the hut, Gualtiero recognises her, but the hermit makes him re-enter. Imogene is urged to return to the castle, but to herself, she imagines that she sees Gualtiero everywhere she looks. (Cabaletta: "Sventurata, anch'io deliro" / "Hapless one, I too am delirious / obsessed by a vain love").
