Joffrey Baratheon (sentencing Ned): My mother wishes me to let Lord Eddard join The Night’s Watch. Stripped of all titles and powers, he would serve the realm in permanent exile. And My Lady Sansa has begged mercy for her father. But they have the soft hearts of women. So long as I am your King, treason shall never go unpunished. Ser Ilyn, bring me his head!
