One-shot VII: Big sister.
After being enchanted by the little turtle ducks in the garden, Izumi and Tenzin would constantly go to watch them swim and sometimes play with them a bit, there were even occasions when they would take some bread from the kitchen to feed them.
That particular day they had taken a large piece of bread, while Izumi cut her piece into small pieces and delicately threw it at them looking for them to approach her without fear, Tenzin just looked at them thinking of a "great plan" to bring them closer and fast to him. So, following his "brilliant plan", Tenzin threw his whole piece of bread into the water almost hitting a couple of turtle ducks, Izumi saw this and tried to push Tenzin away from the water because the mother was approaching seemingly angry; however, Izumi was not so quick and ended up biting her.
"Izumi, are you okay?" her twin brother asked scared, taking his sister's hand that only had a red spot, the girl only nodded with a small smile while her brother took her injured hand "stupid turtle duck"
"But you hit them... you shouldn't have done that; it was clear that she would get angry."
"But she shouldn't have bitten you, my bad, not you."
"I'm the older sister, I must take care of you" Izumi replied proudly.
"We have the same age."
"I'm still a few minutes older than you, Mom told me."
"But... you are" Tenzin thought for a second "you are a girl and boys protect girls, so she shouldn't have done anything"
"I am still the elder and the elder ones take care of the younger ones."
"Then… we'll take care of each other together."
The girl nodded and they got ready to go to the kitchen to steal more bread, but this time it would be for them, for being such good siblings they deserved a treat. What they did not know is that their father saw them from the distance, although he loved the idea that their children were such good siblings and loved each other so much, he also felt a bit guilty and wondered if he had been a good older brother for Azula.
