They are…well, frankly, getting on in years. Or, if you wanted to be Toph-style blunt, they were old. Old as rocks. Wrinkly and grey-haired and besieged with everything from bad knees to bad eye-sight.

Despite the old body she lives in, Katara sometimes feels like she's not a day past twenty. It'd be easier to believe if so many of her family and friends weren't already long gone. It's certainly easy enough when she spares with her long time bending partner.

It is no surprise that Zuko is still kicking. That man could survive anything and spirits, they've certainly weathered a lot. Is it weird that she still finds him attractive? He's not the man he was thirty years ago, nor the boy he was when the war ended, but then she's not the same woman either—a dead husband and three children have wrought their changes, both good and bad—but Zuko is still terribly handsome.

"Focus, Katara." he tells her as fire slices past one ear.

"You focus yourself, hotman," she shoots back, sliding past him and tripping him with a water whip as she goes, "We both know I'm going to win this."

He smirks—that same one that used to give her the tingles when they were children—and throws a barrage of fire at her. Needless to say, she still wins the duel. And afterward, as their children slink away, embarrassed by the antics of their elderly parents, Zuko takes her hands and kisses her cheek. She blushes like a girl and twines their fingers.

"You should come visit me in the Fire Nation," he says as they leave the sparring fields, "My grandson is getting married this spring. It would be a suitable excuse to see one another."

She snorts, "I don't need excuses, Zuko. But I would like to see Iroh again; he sounds just like you over the telephone."

He smiles and the conversation turns to his grandson's many Zuko-like traits (they're eerie and adorable and mostly hilarious to the older people). It's the first time in a while that there is a spring to her step and color in her cheeks. She might not be young and bursting with youth anymore, but being beside Zuko is enough to make her feel like she could save the entire world over again.
