The Master gave many thanks to the Lord God in acknowledgement of His favours at the beginning of his worthy deeds, among which one of them was to reveal to him certain acts of treachery that were being planned against him by people whom he trusted greatly. For there were many who came to him with mischievous desires and perverse hearts, both high-ranking people and those of other stations, showing him signs of love and good service, and yet who did not persevere for very long, as you will see when the time comes.

Regarding others, he did not have a good opinion of them, but nonetheless granted them great favours in order to change their evil intent; abandoning the initial deception bit by bit, they afterwards displayed serious shortcomings and deserved shameful reproach. Among those who were blemished by such an error, it is told, was Dom Pedro, who was the son of the Count of Arraiolos Dom Álvaro Pérez de Castro, who by now had died, as you have heard, and who was married to a daughter of Count João Afonso Telo and Countess Guiomar, by name Dona Leonor. Regarding how the Master got word of this, however, there are varying accounts.

Some say that after Dom Pedro de Castro had conferred with the King of Castile, in a conversation in which João Lourenço da Cunha took part, that he agreed to give him entry into the city through his section of the wall; then he spoke of it with Rui Freire, because he was Galician like him. He believed that he would keep it secret, but Rui Freire revealed it to the Master. The latter, when he saw Dom Pedro in the presence of many noblemen, told him openly what he had been informed of and by whom. Dom Pedro said that Rui Freire was lying, and that he would challenge him in combat. As Rui Freire replied that he was quite willing, and other related things, the Master told them to be quiet, and he paid no further attention to it; and thus the matter was dropped.
