Game of Thrones season 7’s sixth episode ended up online four days early today after accidentally being set live for an hour by HBO Spain.
As such, please take this opportunity to click away if you haven’t watched episode 6 yet as major spoilers are ahead.
Worse still, the end of the episode suggested that Viserion will return as a wight.
It wasn’t made abundantly clear which dragon died (Drogon, Rhaegal or Viserion), but we can safely say it was Viserion, identifiable by his lighter body and red wings.
