One thing about Azula that always bothered me. Like, I get that this was probably because of the 全体, 全体的です direction of the series, but it bugs me how she never got a redemption arch thingy like Zuko did. Again, from a plot-perspective, it may not have been necessary. But it would have been nice to see what became of her, at least. It was probably brought up in LOK where she ended up, but I'd never really know. I stopped watching LOK after book 2 ended.
It was actually brought up in the comics; for a while she was still hearing voices the first set of comics ended with her running g away crying. In the 次 set she comes back (no voices) and kidnaps children. She has a good chunk of her power back and thee were hints at a redemption. I just hope they give it to her because she was only 14 and the product of the same abuse Zuko faced.
