Last night's episode of Game of Thrones may have featured a baby being sacrificed and an adult woman seducing a teenage boy, but the thing that really has fans upset is the accidental reveal of a major character's identity that was supposed to remain secret.
We'll go ahead and warn you now that even if you have read the George R.R. Martin novels upon which the series is based, there are some major GoT spoilers ahead:
Season 4 episode 4 of Game of Thrones ended with a terrifying scene in which a baby is left in the woods, only to be scooped up by a White Walker and transformed.
It's the sort of nightmare-inducing moment we've come to expect from the hit series, but for rabid fans of the books, the scene was hard to watch for a different reason:
The ultimate badass White Walker who steals the baby's soul was revealed in an HBO online synopsis to be the legendary Night's King - a character who has yet to appear in the first five installments of Martin's A Song of Ice and Fire series.
The King has been mentioned briefly in the books as a sort of boogeyman used to frighten young children, but by confirming that the first White Walker is alive and well and snatching up babies, GoT broke an unspoken rule by entering territory not yet covered in the books.
If you're not an obsessive GoT fan, this may seem like a pretty minor offense, but since the show has thus far kept pace with Martin's novels and the Night's King may prove vital to the story's conclusion, it's easy to see why some fans feel betrayed and have taken to Twitter to express their displeasure.
