At the end of the episode, Graham references a famous and deadly dinner between the clans Cameron and Mackintosh, which, as Graham states, served as the inspiration for a Game of Thrones episode (The Red Wedding). Sam replies, "Game of what? Never heard of it..." Sam actually auditioned for multiple roles on Game of Thrones before being cast in Outlander. These roles included Renly Baratheon and Loras Tyrell.
