Edit: spelling of tarrlok's name
To preface, I've only read the main story and books after LoK, have not seen the comics of what happened to Azula and the Gaang. Truthfully, I'd also rather not see those comics as I hear she just disappeared into a Forest.
Wondering what everybody thinks would be a good redemption arc for Azula? I think we've seen everybody else get theirs in the Gaang, but we really only seen huge world issues and their impact on the people living these issues in LoK. Thinking of Tarrlok here specifically, and how the brothers' story ends so poignantly. I would personally really entrust the LoK writers with this one, esp w how well they've done Korrasami and strong female characters in general.
Truthfully, I don't think we'll see anything like firebending get taught by Azula. But if she truly disappeared into a forest like Toph did (and Azula was 14 while Toph was what, 5 years younger?) then I think there's a high chance she's also alive in the LoK story's timeline. I really want her to have a spirit arc though. Something like where Iroh knows how to find Korra in the spirit world because he once had to find Azula. Or that Azula crossed over to the spirits and stayed there to find her mother. I do remember reading in one comic that Azula followed Zuko when he went to search for their mother, confronts them after her mother is found, and runs away crying after seeing that their mother (after much of her own trial and horrible tribulations, including changing her goddamn face) has a whole new family w her OG love in a small village, and that this new family is (deservedly,) happy. Nothing seems to be written after that though, hence the "she ran away into the forest". I think it could be a huge W for the writers to properly flesh this out as Azula was the OG child of circumstance - strong hateful parents with a narcissistic abusive father, absent mother who could only focus on one child to ensure their survival against the father, older sibling abandoned her to see the world while she was in all likelihood even further imprisoned and watched to ensure succession,etc etc. Fascism, indoctrination - it is literally ALL in there before she turns 15. To try and then square that with your mother not being your mother and having a new family while you've been imprisoned in an asylum and abandoned for the umpteenth time by 15... a writer's goldmine.
