Breaker of Chains
Harington appears as Jon Snow in the third episode of the fourth season of Game of Thrones, Breaker of Chains. At Castle Black, a survivor from a massacre at a village warns the Night’s Watch that wildlings are raiding south of the Wall of Westeros. Two Night’s Watchmen who have escaped from the stronghold of a former ally north of the Wall reach the castle, alerting the Night’s Watch that their own men have begun a rebellion. Jon warns that they must range north and stamp out the mutiny, as he overstated the strength of their stretched defenses to King-Beyond-the-Wall Mance Rayder, and if Rayder reaches the mutineers he will learn the truth.
