If it hadn't been for the Avatar, he'd never have lost his bending. If it hadn't been for Korra, he'd probably end up killing himself.
Tahno, as the world knew him, was already dead. Gone was the cheating pro bender, gone was his horde of fan girls, gone was his teammates. Gone was his identity, all that he recognized himself as.
Now there's only another pitied victim of Amon. Another helpless non-bender.
If you ask him what getting his bending taken away felt like, he'd probably punch you. Then he'd apologize, because he's not Tahno anymore. Then he'd explain that it's like being de-aged. Like you're a toddler again. You'd have to learn how to survive day-to-day life without the element that has supported you from birth.
If you ask him what the most agonizing thing about it is, he'd yell at you. Then he'd apologize, because he's not Tahno anymore. Then he'd tell you it's the realization. He'd tell you that he's gotten to a point where keeping himself drunk is an everyday need. He'd tell you that at night he has horrible nightmares, and when he wakes up, he'd feel like taking his own life.
"A watery grave for me," he'd tell you. "Nothing else would be more appropriate."
And he'd tell you all that with so much pain in his eyes.
He'd tell you that while holding back tears.
Around that time, a brown haired girl would probably come into the scene. She'd ask him who you are, then introduce herself to you as Korra. You'd probably recognize her as the Avatar by then.
He'd then tell you, "She's the only one who still calls me Tahno on a daily basis," with a spark that lights his dull eyes. You wouldn't be able to help feeling slightly happy seeing that.
After a little chat, she'd tell you that they needed to go, and she'd bid you farewell. Then you'd say a little loudly so they'd hear, "Good luck!"
And if you were just a passerby, then you probably won't talk to them again.
But you'd probably feel sure in your heart that Korra will take good care of Tahno.
Then you'd ask yourself why you'd care.
Then you'd carry on with your life without thinking about them ever again.
Author's Note: Whew okay. So this is the product of my procrastination. I tried something new for me in this fic, so I'd really appreciate some reviews. Thanks for reading and I hope you enjoyed it.
