[@Andreyich] I guess my concern about the age is the heart of the story -

At the end of the day, ATLA is a coming of age story where characters who have experienced things one way are thrown into situations that force them to look themselves in the mirror and make hard choices, growing as they do into the people they are at the end. It feels like this older character has already gone on this journey and come out, unfortunately, the worst for wear as a result. 

Talk to me more about how he'll grow and what your end goal is for his character arc as he embarks on this new chair in his life.
