Locke

Roose Bolton sends him to hunt down Jaime Lannister. Locke and his men follow his trail until they find him with his escort, Brienne of Tarth.

On the road to Harrenhal, Locke's men try to force themselves on Brienne; Jaime stops them by describing House Tarth and the reward Selwyn Tarth would pay to get his daughter back with her honor intact. Emboldened, Jaime also offers his father Tywin Lannister's gold for his own release, but the mention enrages Locke, who cuts off his sword hand.

Locke hands the two prisoners over to Roose Bolton at Harrenhal, who rebukes him for maiming so valuable a hostage.

When Bolton leaves for Edmure Tully's wedding, a raven arrives from Selwyn Tarth offering three hundred gold dragons to ransom Brienne. Locke turns it down and leaves Harrenhal mocking Jaime, together with Qyburn.

Later he throws Brienne into the bear pit, giving her only a wooden sword for his men's amusement. Jaime saves her again, this time with Steelshanks' forced help, to Locke's frustration.

Locke arrives at the Dreadfort with Roose Bolton and his new wife, Walda Frey. There Ramsay presents them with a broken man who reveals that Bran and Rickon Stark are still alive.

Bolton then orders Locke to find them, promising him lands and a keep of his own if he does.

To carry out the task, Locke poses as a hunter from the Stormlands and enlists as a recruit at Castle Black, where Jon and Grenn train him; it soon shows that he already knows how to fight.

When Ser Alliser Thorne authorizes Jon's party to head for Craster's Keep, Locke volunteers to go with him.

Once at the keep, Locke keeps watch on the mutineers and, while scouting, finds the hut where Hodor and Bran's companions are being held.

When the ambush breaks out, he reaches them and introduces himself as a Night's Watch brother; he cuts Bran's leg to confirm his identity. Before he can take him away alone, Bran wargs into Hodor, who breaks his neck.
