the reason why iroh invented lightning redirection.
so i was rewatching avatar and i had a thought. why did iroh create lightning redirection? like if you think about it the only reason he would need to create a technique like that is if he was planning on fighting another member of the fire nation royal family since they are the only ones who can lightning bend.
its pretty obvious the only one who iroh would need to use this technique against is ozai so that leaves two possibilities. either iroh developed the technique before azulons death because he thought ozai might attempt to seize the throne from him or he developed it after azulons death because he was at some point planning on seizing the throne back from ozai before eventually giving up on that idea. what do you guys think
personally i think he knew his brother was going to try something and developed the technique to protect himself from ozai. i think when lieu ten died, iroh gave up all interest in the throne and instead decided to put his energy into zuko. that said theirs a good bit of time between lieu tens death and zukos banishment so it is entirely possible that iroh developed the technique during those years.
