One-shot: XXVI: Random data.
Author's note: Since college doesn't give me time to write too much, here are some random data from this AU.
I_ The thing about calling Aang "mom" started with a joke he had with Zuko because he would give birth, even when the twins were born, Zuko kept saying that to the point that the twins also called him that way. Although that was only left as a local joke and no one besides the twins or Zuko says that Aang is the "mom".
II_ Izumi has been wearing glasses since she was ten years old, Kya and Bumi mocked her because she did not see well, and they called her "mole".
III_ Tenzin likes painting, actually he is good at that. While Izumi is very flexible and knows how to do a couple of "gymnastics" tricks.
IV_ The twins know many teas thanks to their grandfather but at some point during their teen years, Izumi preferred coffee and knows a lot about its made and different preparations.
V_ The twins found Tenzin's flying bison in one of their "adventures" in an air temple when they were kids.
VI_ Izumi's polar bear dog can't be long in the Fire Nation because of the hot weather, he stayed at the south pole.
VII_ They both know each other's movements and bending techniques (Izumi knows how to move as an airbender and Tenzin knows how to move as a firebender)
VIII_ Although they want to deny it, Izumi is Aang's favorite child and Tenzin is Zuko's favorite child. The twins noticed it in their teen years even though his parents did not do it on purpose.
IX_ Tenzin tried to get Zuko to teach him how to use swords, but he refused, Tenzin rioted until he agreed in his teen years.
X_ It was difficult to separate the twins during their childhood, that's why they had all their vacations together. From going to Ember Island to visiting important places for airbenders or firebenders, Tenzin was there when Izumi met the dragons.
XI_ There was a point in her puberty that Izumi was taller than Tenzin, although that changed when they turned fourteen.
