If you have been watching Game of Thrones (who hasn’t?), you may be aware that the White Walkers are heading South ready to wreck Westeros and presumably eat the Iron Throne (or something..).
But what, pray tell, is taking them so long?
It was way back in Season 5, at Hardhome, that ya boy Jon Snow first fought the White Walkers and since then he has died, came back to life, become the King in the North, and travelled all over Westeros being sullen and looking constantly confused. So what have the White Walkers been doing during that period?
