To adapt in the House of Black and White, Arya throws all her personal effects into the river except for Needle, which she hides in a pile of rocks. At Castle Black, Snow names Thorne First Ranger, but Slynt refuses to follow Snow's orders that he leave to rebuild the Greygard ruin. Snow executes Slynt himself. Lancel finds the High Septon in a compromising situation in a brothel, punishing him by forcing him to walk the streets completely nude.
