Obviously, this is an alternate timeline, since it diverges from canon events. With these different circumstances, I'm trying to keep the character's reactions as canon as possible.
Coercion
Arc I: Swaying the Branch
The end is only the beginning
Two nin were stumbling through the compound that the Sound Nin called home. They were new recruits, freshly indoctrinated in cultivating their hate and lusting for power. However, one nin's power lust seemed to go a bit too far.
"If I succeed, if I gain as much power as I can, I can take over the Sound Nin," the taller of the two said. The other hushed him quickly.
"Don't say that. If you say anything like that, you'll be dead within the hour," he told his brash accomplice.
"Says who?" the other man snapped.
"You saw it yourself, Izaki and Genzai…their bodies in the square? That's what happens to those who conspire against Orochimaru," he explained. "She hears you, she sees you and she kills you."
"She?" the taller questioned.
"They say her eyes look as sightless as the moon, but she sees right through you and sees your lies and forces them out of your body!"
"You're sure you said 'she?' As in not Sasuke or Kabuto?"
"Who's talking about me?" a voice said. Uchiha Sasuke wasn't particularly loud, nor was he intending to intimidate the two before him, but the reaction was the same as though he had been. The two nin scuttled off quietly and silently. Sasuke narrowed his eyes.
"So you don't mind if they talk about you this way, Hyuuga?" he said after he was sure the two nin were gone. Hinata emerged from behind him.
"Doesn't matter," she said.
"You don't mind being part of a ghost story to keep all these kids in line?' Sasuke continued, looking down at Hinata.
"It's like I don't exist. That wouldn't be different from living there. I don't exist there either," she said. "I died in Konoha but it seems my 'ghost' likes to haunt the Sound Nin."
"You're an idiot," he said. "You like being Orochimaru's pet dog? Proudly displaying your kills on his front doorstep?"
Sasuke snorted and left the girl alone in the hallway. Hinata peeked out at him from under long bangs. Sasuke was so consumed with hate for another person, that he couldn't understand her own. She loved that Orochimaru could trust her. She knew it drove him crazy that he could rely on her at every turn, at every slight wind of rebellion. Hinata crushed the unbelievers though she herself didn't believe in Orochimaru herself.
They didn't understand what it was to hate that man, she almost enjoyed killing them for that reason alone. They did not deserve the mere satisfaction of rebellion against him, they could not fight him, they could only fight what he stood for. Hinata hated him. She hated everything about him. It wasn't because he was in charge, it was because Orochimaru was himself. She had almost forgotten Konoha, she scarcely thought about the place save when Sasuke was around. She only thought of Orochimaru, what he thought, what he believed in.
She would be the hook in his side that cleaved deeper and deeper into his flesh.
So how did sweet Hinata end up this way? If you are so inclined to find out, please stay tuned. Please note: I do like Hinata with other characters. This is not my OTP by any means. This is just a challenge!fic. Please do not comment about how Hinata would be better of with [Insert Character Here]. I know she would be. This story isn't about love, if you haven't caught the drift of the narrative so far. I hope to update soon.
