Teacher
He watched her as she repeated the new set of movements he had taught her earlier that morning. She carefully placed her feet, her arms stretched in front of her. She was moving in circles, eyes narrowed in concentration, mouth shut, a drop of sweat fell from her temple. She had been training like this for weeks, she had progressed, but still hadn´t managed to air bend. She was frustrated and he could see that, but she doesn't give up. She is stubborn. She trusts him and his teaching and his advices.
Be patient he tells her.
She trusts him, but is he worth her trust? Can he really teach this energetic girl the way of air bending? He doesn´t admit it out loud, but sometimes he has doubts too. He sometimes wonders that perhaps he is unworthy of this task.
He thinks the spirits have a very odd sense of humor. Everything he knows he had learned from his father. And now his father has been reincarnated as this girl who he has to teach. This restless and stubborn girl, so different from the previous Avatar.
"Korraaaa" Ikki and Meelo arrive on Naga´s back. The giant polar bear dog licked Korra´s face and the girl burst out in a laugh. And it´s in that moment, in that laugh, that he can sense the echo of his father´s laugh. He smiles, maybe she is not that different from his father after all.
She and his father trust him, he simply has to trust her too.
