The Hound tells Arya that he is taking her to the Twins to collect a ransom from Robb, easing her fear that he intends to return her to King's Landing. In the capital, Tyrion and Sansa marry while Joffrey humiliates his uncle by removing the stool he needs for the ceremony. At the feast, Joffrey calls for the bedding ritual and threatens Sansa. Tyrion threatens him in return, forcing Tywin to intervene. Alone afterward, Tyrion tells Sansa that he will not consummate their marriage unless she wants him to, and sleeps separately.
At Dragonstone, Stannis releases Davos after securing his promise not to attack Melisandre again. Melisandre seduces Gendry, restrains him and draws his blood with leeches. Stannis burns them while naming Robb, Balon and Joffrey as rival kings. Outside Yunkai, Daenerys tries to win over the Second Sons, the mercenaries defending the city. Their leaders choose Daario to assassinate her, but he enters her tent carrying their severed heads instead and pledges his loyalty. Beyond the Wall, Sam and Gilly shelter with her baby in an abandoned hut. A White Walker approaches, breaks Sam's sword and moves toward the child. Sam stabs it with his dragonglass dagger, causing it to shatter. He flees with Gilly and the baby as crows swarm the hut.
