Hinata was torn. She had a mini Hinata on each shoulder, telling her what to do. The Hinata in the flowing robes with a yellow ring perched over her head was telling her to gently nudge Neji-niisan awake, and beat him senseless so that she could gently nudge him awake again. The Hinata dressed in tight black clothing with tiny red horns poking out of her hair, told her to kick Neji-niisan in the ribs until she heard a snap.
Hinata was torn because she was trying to decide if she should listen to either of them, or do the right thing and wake him up to interrogate him properly. She decided to do her duty, even though the mini Hinata's made compelling arguments.
"Nii-san," she said, shaking him awake and cringing for allowing such familiarity between herself and the prisoner. "We need to talk." She got no response. Gently she kicked his ribs, which also got no response. She kicked him a little harder, which got her a grunt, but nothing else.
'I hate doing this,' she thought to herself as she performed the hand signals to activate his seal. It was a specific jutsu that was used to wake branch family members up, no matter what, in case of attack. It was a fail proof jutsu that had even been known to work in a genjutsu.
"Shikamaru-kun," Hinata called out.
"What?" Shikamaru snapped. Hinata cringed a little at his tone. Even though she was used to being snapped out, she never liked I when it happened.
"This isn't Neji-niisan. Or any Hyuuga for that matter," she stated simply.
"You used the byakugan on him. Why didn't you know that?" Shikamaru snapped.
"The byakugan can only show through things, and inside of people. Which means, that when I look at a person I can see their chackra system, but not what kind of underwear they're wearing. When I look at someone using a henge, I can see the chackra system of the person, not the person himself or herself," she explained, getting a little agitated by his tone.
"So, why'd you think he was Neji?" Shikamaru asked. He must have sensed that she was getting annoyed; because he asked his question far more politely then he had asked the other questions.
"I knew that it was a genjutsu, because the attacker was a Hyuuga I had never seen before. There are no Hyuugas outside of Konoha. When he engaged me at first, he used standard ninja moves, but soon he assumed the opening move of gentle fist. Which confirmed that whoever was attacking was a Hyuuga, but more then that, he used Neji-niisan's style," Hinata explained simply.
"What do you mean by style?"
"…Um… well… each form of taijutsu is different right?" she asked. Shikamaru nodded, "Well, each person's execution of that taijutsu is different as well. I'm very familiar with Neji-niisan's style, because I spar with him a lot. That's why I thought he," gestures to the unconscious form of the nameless "Hyuuga," "was niisan."
"So how did he mimic Neji's style?" Shikamaru asked.
"… I don't know… The only person I ever heard about doing something like that was Kakashi-sensei, and that was only after he got the sharingan," Hinata sounded insecure.
"An Uchiha?" Shikamaru sounded incredulous.
"Possibly," Hinata said, "It would have to be Sasuke-san though. Itachi-san was taller then Neji-niisan is now when he left. Kakashi-sensei is far taller then Neji-niisan. This means that the chackra system wouldn't fit into the henge, and I would have known that it wasn't niisan."
"Well, I know the one thing that will wake Sasuke up," Shikamaru said, looking slightly afraid. He did the necessary hand gestures, and shouted, "Henge." There was a puff of smoke and Ino-chan stood in front of her. But it wasn't Ino-chan, as Hinata knew her today. It was 12-year-old Ino-chan. "Turn into Sakura-chan."
Hinata nodded and started the hand signals. She followed Shikamaru's lead and changed into the Sakura she knew three years ago. Long hair and all.
Shikamaru got on one side of Sasuke and Hinata got onto the other side. Holding up three fingers, Shikamaru counted backwards silently. "Three, two, one…SASUKE-KUN!" They shouted in unison, before launching themselves at the boy.
The last thing that Hinata saw before she blacked out was the panicked look in Sasuke's eyes as they snapped open, Sharingan flashing.
Hinata blinked several times, trying to make all the blurred objects clear again. One of the objects was pale, with two black circles, and was topped of by red. It seemed to be talking to her, but her ears were ringing, making it difficult to hear anything. After blinking several times, and seeing no visible difference, Hinata decided that the best thing to do would be smile at the red-topped pale object, and explain that she couldn't understand it.
Apparently this was the right thing to do, because the object stopped talking, and smiled? 'Hmm… objects don't smile. Only people smile. Weird.' Hinata went to sleep, the smile she gave "the object" still on her lips.
