Lord Tywin sent his Mountain across the Red Fork with fire and sword, hoping to draw your lord father. He planned for Lord Eddard to come west himself to deal with Gregor Clegane. If he had he would have been killed, or taken prisoner and traded for the Imp, who was your lady mother’s captive at the time. Only the Kingslayer never knew Lord Tywin’s plan, and when he heard about his brother’s capture he attacked your father in the streets of King’s Landing.”
