While I was doodling at school, I thought of the possibility that what if later in The Legend of Korra, Tenzin got his bending taken away by Amon?
I started thinking of my own scene that Tenzin’s airbending was taken away while Korra was watching which triggered the avatar state. Then it allowed Aang to take over Korra’s body to fight Amon and help his son (like Roku did in episode 8 in Avatar: The Last Airbender).
I dunno why I drew this and I really hope something like this doesn’t happen because I love Tenzin! TT^TT
