***Naruto***
After fainting in the Land of Iron, Naruto was left resting in a room. He insisted on finding Sakura with them, but Kakashi-sensei managed convince him to stay. And leaving Yamato-taichou with him to watch over the kyuubi host.
"Do you know what causes hyperventilation, Naruto? Stress and anxiety. Unless you have stroke or some lung diseases. So don't stress yourself up again. It's no use if you keep fainting." said Kakashi as though coaxing a child. "And Tenzo will protect you if anything happens." Yamato winced.
"As though I need looking after, I'm not a toddler. And why did you call Yamato-taichou Tenzo?" He wondered if Sakura hammered the information about the hyper-thing into Kakashi's head. He didn't know that one of Kakashi's teammate, Rin was too a medical ninja. When he over breathed and passed out after thinking too much about Sasuke, the white fang's son had emptied his weapon pouch and covered it over Naruto's mouth to increase the amount of carbon dioxide in his blood. Naruto felt embarrased as it made him look like throwing up.
Kakashi ignored his question. "You are being hunted down, Naruto. Just stay here and be good. Sai, take me to Sakura, then disperse before she finds out and land a punch on you."
Naruto recalled his moment with Kakashi before he left with Sai's ink clone. He felt angry with himself. Now you can't do anything, because you hyper-what-ever-it-was, he thought grumpily.
Yamato wasn't doing much good in comforting Naruto either. He had tried to make Naruto put Sasuke off his mind without any success in the past half hour. Even worse, he had made him think more about him. It seems that the only way is to let go of him. But how?
"Do you mind another chat, Naruto?" A voice floated down from above. "This time with a little action."
Naruto jumped, and looked up. Right in the middle of the hole he created on the roof earlier that day, stood, to his horror, is Uchiha Madara. Right next to him is what made him yell. "Sasuke!"
***Sasuke***
Sasuke looked down at Naruto's stunned expression. He felt uneasy at the look on his face. Although he had promised Madara to help in his Moon Eye plan, he still felt a pang of guilt when it came to capturing Naruto. He was his best friend after all. But it doesn't matter anymore. Who needs friend when you have a powerful ancestor with you?
