Tyrion Lannister receives some hostile reactions among the smallfolk of King's Landing when he is inspecting the devastation left beyond the King's Gate after the Battle of the Blackwater. He assumes that, if he was not protected by Ser Bronn, the people would pull him off his horse and smash his face in with a cobblestone, as they did for Ser Preston. When Ser Jaime Lannister assumes his duties as Lord Commander of the Kingsguard, he notices that in his absence the White Book has not been updated, as that is the Lord Commander's duty, and that the death of Ser Preston has yet to be recorded. Lord Petyr Baelish tells Sansa Stark that when he was arranging the contract for a marriage between King Joffrey I and Margaery Tyrell in Highgarden he let his men spread information about the gruesome details of Ser Preston's death. Littlefinger suggests that by doing so, he successfully planted the idea in Lord Mace Tyrell's mind that his son Ser Loras should join the Kingsguard in order to be able to protect his sister.
Princess Arianne Martell asks the guilt-ridden Ser Arys Oakheart during one of their dates whether he believes that he is the only member of the Kingsguard who ever loved a woman. Arys shares that he knew, among other things, that Ser Preston used to visit a draper's wife when the husband was away
