Update? It’s great so far!

This is great keep writing!

After so many years it's probably in vain, but I hope someday you'll continue this. If there's one thing I really hate, it's seeing stories with so much potential being left unfinished. Especially since I know from your other works that you have the skill to manifest that potential onto the page.

Best of luck to you, regardless.

I really hope you come back to this someday, you managed to turn Azula into someone quite endearing without changing her character too much, and I really want to see her get a happy ending.

One another note please cut out those (x) referring to end notes, they serve as a distraction when reading the story. It's usually a bad idea to break the fourth wall with anything, no matter how slight.

"Let me have a look." She had, indeed been bitten"
But where was she bitten? Might seem unimportant, but vagueness rarely helps immersion.

She was the same clothes - She was wearing the same clothes

It's pretty immersion-breaking to have AN references in the text like (1) etc.
If you find it important add it to the story, otherwise just remove the references and explain more fully in the AN, don't do this halfway thing.

give my brother to - give my brother time to

pleasent - pleasant

a decent general idea what - a decent general idea about what

Or, as the saying goes, else - Or, as the saying goes, 'or else'

typo
went their - went there

This story is most likely abandoned, but damn it was a good (if short) ride

shame this wasnt continued, your SI makes for quite the affably evil character

it should be cool to see our "hero"'s first interaction with aang, especially as they appear to be on good terms later on if the notes are any indication
