Mockingbird

Harington appears as Jon Snow in the seventh episode of the fourth season of Game of Thrones, Mockingbird. Jon and his ranging party return to Castle Black after crushing the Night’s Watch mutiny north of the Wall of Westeros. Jon warns the Night’s Watch leaders that King-Beyond-the-Wall Mance Rayder’s army will attack the tunnel through the Wall, and that it should be sealed, but he is overruled due to internal politics, and sent to keep watch at the top of the Wall.
