Oh no!
We’re sorry that you felt less excited somehow, that’s not cool. However, we don’t get any advance notice on plots from anyone at Nickelodeon or the Korra show, so the guess that there would be a “Dark Avatar” that showed up somewhere was based on context clues in the story.
We don’t want to spoil anything for anyone, but we do want to guess crazy things. Like how Devindra always says Bolin is going to die.
Please don’t be mad! We will never spoil anything that hasn’t been made available to the fandom because we get access to everything at the same time you do!
