Pedro, dressed as an employee of the Vidago Palace, enters Carlota's room at night. The two have many explanations to ask each other. But Livia's arrival prevented them from speaking. They agreed to meet at the cabin the next day.
On leaving, Pedro crosses with the Perliquitete sisters, who recognize him and are scandalized, because they knew about Pedro and Carlota's relationship. The sisters are in fleas to tell the Countess what happened.

Pedro, because when he read the letter, Carlota told him that everything had been a mistake and put an end to his novel.
As they talk to each other about it, they realize that the letter Carlota wrote and the letter Pedro received aren't the same. What has happened, then? Carlota finally realizes everything. It was her mother who changed the letters.
When the sisters Perliquitetes are almost telling the Countess that they saw Peter the night before, Carlota arrives and confronts her mother by showing her the fake letter. Lívia and Carlota argue.
