The Mountain and the Viper

Harington appears as Jon Snow in the eighth episode of the fourth season of Game of Thrones, The Mountain and the Viper. At Castle Black, Jon and the other Night’s Watchmen discuss the impending attack on the Wall of Westeros by the wildling armies of King-Beyond-the-Wall Mance Rayder. Realizing that they are hopelessly outnumbered and that after Mance’s armies, the undead White Walkers will attack in turn, the Night’s Watchmen prepare for death and plan that the last of them will cremate the rest.
