"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'm your
King treason shall never go unpunished! Ser Ilyn,
bring me his head!"—Joffrey Baratheon
