 At Luys's instigation, Alberto abducts the woman he thinks is Jacinta (actually Estefania) on her way to the marriage ceremony.Finding that he's been fooled and that Jacinta has eloped, the flexible Alberto marries Estefania (he's a more attractive match for her than Don Pedro).Don Carlos, confronted with the fact of a new son-in-law, takes rueful comfort in the idea that at least Francisco is an heir; Francisco, however, offers his patrimony to his older brother—who refuses it.
