AN: I couldn't help but want to write more of this… I'm such a sap. Really, just read what's below.
Forever Young II
Katara is surprised to have gone to bed covered in fur blankets only to wake up in a field of grass, looking down at her no-longer shaking, wrinkled skin but at a youthful body and hands.
Looking up, she sees a bright blotch of orange and yellow standing on a nearby hill. She can't see his face or any real definition, but she doesn't need to. She knows who it is already by the swell in her chest.
She gets up and runs, runs like she hasn't done in years, towards him as he does the same. They collide more than meet, and they wrap their arms around each other, because she's grasping for reality.
"Where am I?" Katara asks into his chest before pulling up to see his face.
"In the spirit world," Aang says with a grin that splits his face. He looks just like he did when they were married, young and glowing and entirely happy. His eyes seem more like bright silver than grey, but the color of his arrows is still that sky blue.
"What do we do here?" she can't help but ask.
"Spend the rest of eternity together," he laughs as he brings her close to him.
"I see you're as romantic as ever," she manages to get out through her wide smile.
"I'm really only telling the truth, like I always have," Aang says through a smile as well.
"Hey!"
At the new voice, Katara turns her head to see her brother and Toph standing on a hill, holding hands and similarly young.
"Don't hog her to yourself, Twinkle Toes!" Toph calls as she begins sprinting over, hauling a grinning Sokka along with her.
As they hug and are reunited once again, Katara didn't think she would have been able to cry in the Spirit world. But she does, and the sobs come deep from her chest and seem to echo out in this new world.
