A Feast for Crows
Garrett, a child hostage sent to King's Landing after House Paege submitted to the crown after the Red Wedding, is named a squire to Ser Jaime Lannister. He accompanies Ser Jaime on the ride north to end the siege of Riverrun.
When Ser Daven Lannister and Jaime discuss the lynching of Lannister foragers, Daven suggests that some lords of the Trident might be responsible as they still support the northern cause, even though they formally submitted themselves. This makes Jaime think that he would hate to execute Garrett as a son of a river lord, as he has grown fond of him. Ser Jaime then suggests that the Brave Companions are more likely suspects.
