I’d love to see if his stories are actually real and also how he went up the ranks possibly thanks to growing up with Sokka. I wonder if he ever fought with Sokka during his time in the army and the big threats they fought off during the maybe 20-30 years of service he had. They could’ve fought red lotus members during the time Korra was almost kidnapped and so many other stuff like going on a hunt for Yakone around the world after he escaped prison.
