A Game of Thrones
A Clash of Kings
Robb Stark, King in the North, and Tyrion Lannister, the acting Hand of the King, attempt to negotiate Tion's release. Robb offers Willem and Tion in exchange for Arya and Sansa Stark. Tyrion declines that offer, but offers Lord Medger Cerwyn and Ser Donnel Locke for Tion and Harrion Karstark and Ser Wylis Manderly for Willem. No agreement is reached.
A Storm of Swords
Torrhen and Eddard Karstark, the younger sons of Lord Rickard Karstark, were both killed by Jaime Lannister in the Whispering Wood. Rickard wants to kill Jaime in retaliation, but Jaime is released from captivity at Riverrun by Catelyn Stark without Robb's knowledge.
When Robb's host returns to Riverrun, Lord Karstark feels robbed of his revenge against the missing Jaime and chooses Willem and Tion instead. With ten men the Karstarks surprise and kill the cousins and two of their House Tully guards. Catelyn observes that one of the boys was blond (presumably Willem as a Lannister), wore his hair long, and was trying to grow a beard. He was probably killed in his sleep. His cousin was brown-haired (presumably Tion as a Frey) and had fought for his life. Both were pale from their imprisonment. Furious about the killing of his captives, Robb executes Rickard with his accomplices at Riverrun.
Robb: I saw your sons die, that night in the Whispering Wood. Tion Frey did not kill Torrhen. Willem Lannister did not slay Eddard. How then can you call this vengeance? This was folly, and bloody murder. Your sons died honorably on a battlefield, with swords in their hands.
Rickard: They died. The Kingslayer cut them down. These two were of his ilk. Only blood can pay for blood.
