HBO's Game of Thrones has a reputation for serving up a game-changing penultimate episode each season, and last night's ninth episode, "Battle of the Bastards," was no exception.

Spoiler alert: Jon Snow and Ramsey Bolton had their final reckoning last night, and if you haven't watched it yet, then don't watch the video below in which the cast, crew and showrunners take you behind the scenes on Westeros' biggest battle yet.  If you have seen it...enjoy!
