Okay so everyone remembers how in the schematics Tenzin yells at Korra for being irresponsible for using the Avatar State like a toy? I’m pretty sure that everyone (including me) thought that was just him being typical, killjoy Tenzin who was acting naturally as an airbender and all that jazz. You know, saying how spiritual things are sacred and must be treated right and blah, blah, blah…
But then I started thinking.
What if that’s not the reason he yelled at her?
What if he just panicked?
Maybe - when he was much, much younger - Katara told him of the time she and his father, Aang, fought underneath Ba Sing Se and that he went into the Avatar State and died, almost ending the Avatar line forever. And he never quite got over it and now seeing Korra using it so carelessly makes him think that now she’s more vulnerable to getting hurt and possibly being killed.
Just like his dad.
Except this time there wouldn’t be any spiritual water from the oasis to save her.
So it’d be like losing his dad all over again.
Just some thoughts of mine.
