If you could do it all over again, what would you do differently?
A person asked themselves that question, or were asked that question, at least once in a lifetime. Nearing the ripe age of fifty, Aang finds himself wondering at least twice a day. If he'd accepted his destiny, he could have helped end the war and saved the world from a century of suffering at the hands of the Fire Nation. Perhaps Gyatso would still be alive.
Even now he still feels a sting of guilt for not being there when it happened.
But would he have still been able to meet Katara, Sokka, Zuko, Toph and everyone else who helped him when he finally did accept his destiny? Aang doesn't want to imagine life without them, especially Katara. Even at the tender age of twelve, he knew it was love at first sight when he woke up in her arms. She was his best friend, his teacher, his confidante.
He gazes at her as she sleeps peacefully against him.
If you could do it all over again, what would you do differently?
Katara stirs a bit in her sleep, nestling her face further into the crook of his neck, and Aang smiles. The answer is what it always was and always will be.
Not a thing.
