Spoilers follow for those yet to watch Game of Thrones Season 8 Episode 4, ‘The Last of the Starks’.
For nine long years since Game of Thrones debuted in 2011, this grave threat to the realm posed by the White Walkers had been hanging over the entire show, affecting not only how we watch and interact with the show but how the characters themselves conduct themselves around each other.
‘Winter is Coming’ has not only been the unofficial motto of House Stark, but also of the whole show. We were led to the believe the greatest threat to mankind was the White Walkers marching south, leading all the armies of Westeros and Essos gathered by Jon and Daenerys to take them on in one final battle for the survival of the realm.
