Okay, so I decided that leaving you hanging like that is SUPER mean sooo this chapter is about how Katara's baby didn't get killed in the accident. Disclaimer: I do not own ATLA! Now, on with "Pregnant? HOW?"
One day, Kaya was watching over her daughter's body as the healer healed, when suddenly the healer gasped with shock and said, "She… she's pregnant and her baby is completely healthy…" She was surprised herself, and so she went to talk to Sheng Ming, the spirit of life. When she reached where Sheng Ming lived, she bowed down to the spirit and asked:
"How is my daughter's baby still alive?"
"Hello, Lady Kaya. Nice to see you. I've missed seeing you around here. I knew you would come to ask about your grandchild someday soon. I have been assigned to be the guardian of this child, and since your daughter and her partner are worthy souls, I have made it so the child will, in fact live." Sheng Ming told her old friend.
"Can you please tell my daughter?" Kaya asked the bright spirit.
"Of course, that will give her motivation to return to life quicker. I will go to her in a dream right now, because she is still sleeping."
Katara's dream
"Hello, Master Katara! I am Sheng Ming, the spirit of life. I have a special message to you and your fiancé."
"Hello, Sheng Ming. What is it you have to share with Aang and I?" Katara questioned.
"Katara, in the physical world, you are… pregnant" Katara's face turned from shock, to joy and then to confusion.
"But… how? How can I be pregnant?" She asked the spirit.
"I have been assigned to be the guardian of your child, and since you and your partner are worthy souls, I have made it so the child will, in fact live." She said, repeating what she said to Kaya earlier. "You must go tell your fiancé, now!"
Spirit world, with Aang and Katara
"Aang, sweetie? Wake up, I have very special news to share with you."
"Kara? What's wrong?" Aang said groggily.
"Aang… I'm pregnant."
"I won't even ask how, but I'm sure it has to do with Sheng Ming. Katara… WE'RE GONNA BE PARENTS!" Aang shouted happily as Katara tackled him and he showered her with kisses.
All better now? Good… I hope so =)
