Catelyn and Brienne eat alone in the Great Hall, while outside, the castle celebrates Edmure's victory and Robb's recent capture of the Crag. She has learned that Bran and Rickon are dead.1 Maester Vyman received the word from Ser Rodrik, who is marching to retake Winterfell. Catelyn tells Brienne what happened. Catelyn is torn by grief and despair. She soon begins to talk of her daughters and how she wants to kill Theon and all the Lannisters, and says she has sent wine to Jaime and bids Brienne to come with her to the dungeons at midnight. She goes to see Hoster, but he is asleep. Maester Vyman says he has given Hoster dreamwine. Catelyn tells the maester to go join in the celebration. She sits with her father for hours, until Brienne comes to tell her it is midnight. They go to the dungeon, where she leaves Brienne to see she is not disturbed and goes to Jaime's cell.
Jaime has not touched the wine. He has not been allowed to shave since his capture, and he has a thick yellow beard and long dirty hair. Jaime is arrogant at first, but just as Catelyn is about to leave, he says he will cooperate. He agrees to tell her what she wants to know in exchange for information on what is happening in Westeros. Jaime admits to fathering Joffrey, Myrcella, and Tommen and to pushing Bran. Catelyn asks him about the assassination attempt on Bran, and he says the Lannisters are innocent. Catelyn tells him of the dagger and how Tyrion won it from Petyr, but Jaime says that Tyrion never bets against him. He did remember the dagger changing hands though, because Robert showed it to him afterwards as he mocked Jaime.2 He talks some of Aerys and Brandon Stark. Brandon was on his way to Riverrun to marry Catelyn whe he heard that Lyanna had been taken by Rhaegar. He came to the Red Keep with Ethan Glover, Jeffory Mallister, Kyle Royce, and Elbert Arryn shouting for Rhaegar to come out and die. Rhaegar was not there, and Aerys II had them all arrested. The fathers of all the men were commanded to come and answer for the treason of their sons, and all the fathers and sons were executed save for Ethan. Lord Rickard demanded a trial by combat, and Aerys II granted his request, declaring fire to be the champion of House Targaryen and having Rickard cooked in his armor. Brandon was made to watch and bound with a wet leather cord around his throat and his longsword just out of reach. As he watched his father roast alive, he strangled himself trying to free him. When he is finished, talking Jaime notes the irony that he is loved by one for a kindness he never did and reviled by so many for his finest act.3 Jaime, now well and truly drunk, begins insulting Catelyn and Eddard, and Catelyn calls for Brienne and asks for her sword.
