Anon asked: What would happen if Katara did manage to cure Zuko's scar in time before anyone stopped her (impling this is Azula finds Zuko's scar extremely erotic au)?
Azula would be disappointed, and settle for giving small scars during sex. After both their Agni Kai and her redemption, Azula would be happy that she left a mark on him, and she likes that it is something that's hidden away from other people's eyes… but she also wanted to give him one that everyone could see.
The day after their wedding, everyone at the palace is talking about how the Fire Lord and his Fire Lady asked to have bandages and healing balms on left on their chambers, how they both screamed in the middle of the night, how the princess keeps bringing her hand over her chest like there's a wound there…
And about how the Fire Lord will have a scar on his eye, like he did as a young man.
