A Game of Thrones
A Clash of Kings
Perwyn is a member of the party that escorts Catelyn as she travels to treat with Renly Baratheon at Bitterbridge and Stannis Baratheon at Storm's End. When they return to Riverrun after Renly's death, Perwyn is informed of Robb's victories in the westerlands by his half brother, Martyn Rivers. Perwyn jests when he sees hanged plotters.
A Storm of Swords
While under house arrest for freeing Ser Jaime Lannister, Catelyn watches Perwyn and Martyn, who fought in the Battle of the Fords, unexpectedly leave Riverrun. Catelyn later learns the Freys left because of Robb's marriage to Jeyne Westerling instead of one of Walder's daughters.
Catelyn is surprised that Perwyn is not present at the Twins for the wedding of his sister, Roslin Frey, to Catelyn's brother, Lord Edmure Tully. Lothar Frey explains that Perwyn is away and delayed by the flooding of the Trident. As the Red Wedding begins, Catelyn thinks of the absences of Perwyn, Olyvar, and Alesander Frey, as well as Roslin's crying, as warnings of House Frey's betrayal.
A Feast for Crows
Perwyn is present at the siege of Riverrun, where he tells Ser Daven Lannister that his sister Roslin is in love with Edmure and is praying for a girl. Unlike most of the Freys at the siege, Daven approves of Perwyn.
Quotes by Perwyn
