This is a very well-done piece of introspection. I enjoyed reading this. I like your take on Noatak's line of thinking when he left North Pole. It didn't quite clicked with me when he told his brother that he was weak. I also like your take on the mysterious 26 years of Noatak' life, and on how he formulated his idea of taking bending using his bloodbending.

I would really like to read one of this in Tarrlok's perspective. How such tender-hearted child grew up to be such a corrupt politician, but of course, it's a given that Yakone has something to do with it.
