It is then revealed that "Félix" is actually don Carlos, the nephew of don Diego who has been stationed with his regiment in Zaragoza. Carlos says that he was on his way to Madrid so that he could visit his uncle. Diego is suspicious of this reason and orders Carlos to go back to Zaragoza immediately. Carlos protests that the horses are too tired, so Diego, still trying to hide the fact that he is engaged, sends Carlos somewhere else to spend the night. As Diego is like a father to him, Carlos cannot disobey, so he and Calamocha leave without an opportunity to explain to Francisca what is going on.
