Episode 9 of a season of Game of Thrones has become something of a cultural event, standing slightly apart from the rest of the show. Diehards, casual fans, even those who merely take a passing interest - all are aware that the ninth episode is the big one, where the shocking event is likely to happen. It all started back in the first season, when Ned Stark had his head chopped clean off, and has continued with the epic Battle of Blackwater, the infamous Red Wedding, and the huge-scale wildling attack on The Wall.

These are the watercooler moments that get everyone talking, the ones destined to set the internet ablaze like wildfire, and inspire countless memes, gifs, and YouTube reaction videos.
