Aang

I had been in Ba Sing Se for over a month now, on important Avatar duties. I knew it was important and everything to be there, but I couldn't help being help being a little irritated. I hated politics. It just seemed like a bunch of cranky people yelling at each other and not getting anything done. Well, anything important anyway. The fact that I was supposed to only be here for about two weeks wasn't helping matters any. It was a little selfish of me to neglect the other nations by spending so much time in the Fire Nation, but I couldn't help it. It wasn't my fault that Zuko lived there, and that he couldn't travel much because of his duties.

"Oh. Hi, Roku." Roku hadn't popped up out of nowhere since the end of the war, nearly ten years ago. I had talked to him since then, of course. I had always gone to him, though. "Do you have an important message for me?"

"I do, Aang. You might want to sit down." That didn't sound good. "Nothing's happened to Zuko, right?"

"No, no. My great-grandson's fine." Oh. That was a relief. Roku looked a little unsure of himself, which was unusual for him. "You're pregnant." That was funny. I could have sworn that he said I was pregnant.

"I…what?" Roku definitely looked uncomfortable now.

"You're pregnant. With twins. Both boys, one will be an Airbender, the other will be a Firebender." I was pregnant? Really? Awesome! A horrifying thought occurred to me. I knew how girls gave birth…well, in theory, anyway. I also knew that if I had to give birth the same way, it was not going to work.

"Roku, I'm glad to be pregnant and all, but how, exactly, am I supposed to give birth?" If Roku weren't a spirit, I would have sworn he was blushing.

"The babies, will, er, come out the same way they came in, Aang." (A/N: I hope that's how mpreg works. I really do.) Roku wouldn't meet my eyes. I realized suddenly that it was probably a little…awkward for him to be discussing anything related to the sex life of his reincarnation and his great-grandchild. Whoops.

"So, um, how is it that I got pregnant. I mean, I know what Zuko and I did, but not how I managed to get pregnant since I'm a guy."

"You were supposed to be born a girl, Aang. The Avatar Cycle alternates between males and females, along with the nations. No Air Nomads were carrying daughters when I died…so you were born a male. The fact you were supposed to be female means that the spirits were able to help you conceive."

"So I can have more children with Zuko?" I liked the idea of having lots of kids running around. Lots of little Zukos.

"Yes. You will always be the one who bears them." I figured that was why I had gone through a phase where I wanted to be the bottom before I left. If I was the one who could conceive, then it made sense that I would have to be the one on the bottom. I couldn't wait to tell Zuko about the babies.
