Lol, I loved the part were Natasha said it was HER job to pick names first - not his! XD That was awesome. And I'm happy that Zuko's scar was healed almost all the way, if I remember right he had some issues with it. Poor guy - HATE his Dad, I hate - I hate - I HATE him... Hate his sister, too. **.

But enough of my ranting - this was a very good mini sequel, and you should maybe think about making one with the kids older (Maybe Katara, Aang, Sokka and Toph's, too? If Toph is even in your story that is) and kicking as much ** as their parents did when they were they're age... Maybe. If you want too...

I'm just ranting out ideas here, sorry.

Hugs,

good start
