“She’s exactly like her mother.” –Brynden “The Blackfish” Tully
Brienne and Podrick arrive at Riverrun, taking in the current state of the siege. When Lannister guards draw close, she calmly informs them she has come to speak with Jaime: “Tell him I have his sword.”
Outside Jaime’s tent, Bronn surprises Pod with a chokehold. Happy to find the squire still alive, Bronn teaches the young man his own style of fighting.
Meeting privately, Jaime is surprised and proud that Brienne fulfilled her oath to Catelyn Stark. Brienne explains Sansa’s desire for aid from the Tully army, and requests Jaime’s permission to enter the castle and plead her case to the Blackfish; should he agree to help his niece, Brienne asks that the Tully army be allowed to abandon the property unharmed. Jaime gives her until nightfall. Brienne removes Oathkeeper, but Jaime shakes his head, “It’s yours. It will always be yours.” Brienne keeps the sword, but reminds Jaime that should it come to battle, she will be obligated to fight for Sansa’s kin against him.
Rejecting Brienne’s idea before even looking at Sansa’s letter, the Blackfish finally relents and reads it. Although he understands that Sansa wants her home back, he says he has to defend his own home foremost, and cannot offer his niece aid.
Jaime visits the captive Edmure Tully to offer a deal, and mentions his admiration for Catelyn, Edmure’s sister. Edmure declares Jaime a madman, indicating his unwillingness to work with the Kingslayer. Uninterested in negotiating, Jaime speaks of the son Edmure has yet to meet, and warns there is nothing he will not do to win this battle and return to Cersei.
Standing on the drawbridge, Edmure demands entrance to the castle as Lord of Riverrun. Despite the Blackfish’s orders, the bridge is lowered to the castle’s rightful lord. Once inside, Edmure issues a surrender and instructions to find his uncle. The Blackfish leads Brienne and Podrick to a skiff, but does not flee with them. “You’ll serve Sansa far better than I ever could,” he says before drawing his sword.
The castle taken, and the Blackfish dead, Jaime looks out on the water. Seeing the skiff, he knows he could have his men seize Brienne and Podrick as enemies. Instead he raises his golden hand in farewell to the boat’s passengers. Brienne, returning his gaze, does the same.
