knowledge
Jinora liked books. It was a fairly simple observation for anyone who met her. She craved stories and, while her life got to be fairly exciting every once in a great while, she never truly gave up living vicariously through fictional characters.
Unlike Ikki's constant questions, Jinora gained information through subtlety. She observed and deduced. She didn't need things to be spelled out for her. There was power in silence. This was something neither of her siblings understood. It seemed it was a knowledge Jinora had gained from their father. She did wonder, however, if Ikki and Meelo might discover the same in time.
She wasn't naive enough to think that her books and observation would be enough though. Jinora was smart. She understood that if she wanted her life to be as amazing as the people she read about she had to do something about it. Because that's what the characters in her books did. Hell, that's what the other people in her life did.
Her mother confessed her love for her father, regardless that he was with another woman at the time. It may not have tied things up in a pretty bow, like in her books, but Pema and Tenzin seemed happy. And, after all, if that had never happened Jinora wouldn't exist.
Korra ran away from the South Pole to learn airbending. While she didn't succeed quite like she wanted to, she went out and did it.
Korra was exactly the type of person Jinora hoped to be but knew she could never quite accomplish. Korra DID so much. She didn't think about it. Didn't worry about it. Didn't stress.
Well, she did, but not to the extent the air bending family often did. The point was that she never let that worry or stress hold her back. And now, in these dark times, Jinora wanted nothing more than to uphold that kind of fearlessness. Like Korra. Like the characters in her books. Helping Lin Beifong was only the beginning. If her grandfather could fight in a war at twelve years old then she would be damned if she couldn't fight at ten.
If only Tenzin knew he'd created a little warrior girl.
