"Theon is my mother's last surviving son. When his brothers died, it shattered her. His death will crush what remains of her... but I have not come to beg you for his life."
"Wise. I am sorry for your mother, but I do not spare the lives of turncloaks. This one, especially. He slew two sons of Eddard Stark. Every northman in my service would abandon me if I showed him any clemency. Your brother must die."
"Then do the deed yourself, Your Grace." The chill in Asha's voice made Theon shiver in his chains. "Take him out across the lake to the islet where the weirwood grows, and strike his head off with that sorcerous sword you bear. That is how Eddard Stark would have done it. Theon slew Lord Eddard's sons. Give him to Lord Eddard's gods. The old gods of the north. Give him to the tree."
