A/N: I'm not even going to bother with an intro or how this idea came into mind. Hopefully you can pick those out yourselves. I hope you enjoy. This is only a tease, scenes—bit of cliffhangers. Enjoy.

Prologue

"I have some news that might interest you."

Instead of giving a verbal reply, Sasuke only waited until the elder Uchiha could finish.

"What are you talking about?"

"It's something that might definitely interest you. Your brother made sure to keep this disclosed, especially from you."

"Sasuke, what is he getting at?" Naruto questioned.

"I'll just cut right to the chase. Remember when you were told your brother killed everyone in the clan, turns out, he didn't kill all of them."

"What the hell are you-"

Madara spoke louder this time.

"We are not the last Uchiha...there is another, another heir. One is still in the womb, the child of your brother and lover."

Sakura looked down at Obito, her jade eyes raking over her enemy. Well, now turned ally. A part of her wanted to see him suffer for the deaths he committed—but that wouldn't be right. She wasn't looking for revenge.

"I should hate you..." she whispered, low enough so that he couldn't hear.

"...but you saved Naruto..." She fingered the lock she wore around her throat, nearly forgetting about the gold heart lock.

"Thank you..."

"R-rin..."

Sakura frowned in confusion.

"Rin? Did you say...Rin?"

He coughed. It seemed as though he didn't have long. He looked up at her.

"You said Rin, didn't you?" Sakura asked.

"Yes...she was...an old teammate of...mine and Kakashi's..."

Sakura's eyes widened in shock. She'd actually had heard the name Rin from a long time ago...she couldn't believe she'd almost forgotten until now.

"Rin...you mean, Nohara Rin?"

Obito's entire body went ram rod straight, his head slowly coming up to level with her, although he was still on his knees somewhat. His entire body began to shiver despite it not being cold. The look in the girl's told him that she was just as familiar with the name Rin as he had been.

"How do you...know her? She died a long time ago..."

"I think you're mistaken..." Sakura shook her head.

"Girl...I...know what I'm talking about...she died by Kakashi's hands..."

"I'm telling you that you're wrong," her voice raised.

"She's not dead...she's alive, very much so."

"If you're playing games with me...it's not funny..."

Sakura sighed in frustration.

"Someone obviously didn't tell you the whole story. And I know it well..."

Sakura crouched in front of him.

"The Rin Nohara you saw die all those years ago, wasn't Rin Nohara. You're going to listen to me and you're going to listen to me well."

Obito shook his head. This girl couldn't possibly know Rin, if so, how and why? Kakashi kept to himself and it wasn't as though he had told her anything. Then again...

Sakura continued to speak.

"I'll cut to it, Rin Nohara is a twin, well, was. That girl you saw pierced by Kakashi's chidori was Rin's twin sister, Haruna Nohara. When she and Rin were together one afternoon, she decided to take the mission Rin was given because she didn't want her sister to go to the Mist Village. It was Haruna who was forced to become a jinchūriki of the Three-Tails, it was Haruna who died. Not Rin Nohara."

"The...hell...are...you...talking about." He coughed again.

"Haruna made sure to get information on both you and Kakashi. She copied Rin's habits and personality right down to a science. She didn't want Rin to die on that mission, so she took her place."

"Why..."

"I wouldn't expect you to understand...if you don't believe me, fine."

"How do you know all of this? How? Why?"

Sakura touched that same locker around her throat, tucking it into her shirt from his view.

"My mother knew her well...well enough to give her a new life away from Konoha..."
