Sasuke's eyes scanned the area ahead of them vigilantly. He refused to be caught unaware like he had with the demon brothers. When the next attack came, he wanted to know it was coming. As he scanned he noticed that the green eyes of Sakura were still staring at him. At this point he was almost used to her constant gaze. He knew that most girls in their class had crushes on him, but he didn't understand why. Especially when he kept them so far away from himself that none of them really knew him. Including the pinkette who watched his every step.

"Let it go." Tobio whispered to the girl.

"Idiot, you don't know what you're talking about." Sakura stuck her nose in the air.

"That you're just like all of the others." He stuck his hands in his pockets with a smirk. "All of you always talk about how you love Sasuke, but you don't know anything about him, hell none of us do."

Sakura was about to snap back when she started to realize that Tobio was right. All she really knew about Sasuke was that he is the last of his clan, and there was a rumor he likes girls with long hair. Other than that, she really didn't know much. They had been classmates for years, and then teammates for months now. She looked back at him again, and this time it wasn't the same wide eyes she usually watched him with. Now curiosity shown behind them, revealing a lingering question in her mind. 'who is Sasuke Uchiha'?

Sasuke froze for a moment causing Kakashi to reach for his weapons pouch. Sasuke relaxed as a white bunny hopped into the middle of their path. "Look at that." Tobio said slowly walking up to the bunny. He reached down and picked it up and rubbed its stomach.

Kakashi knew something was wrong. "A wild rabbit would never let you pick it up."

"Sensei?" Sakura questioned the man before his eyes widened.

"Get down!" He screamed throwing Sakura and Tazuna to the ground.

Sasuke dove to the ground as a massive sword flew over his head and planted itself into the side of a tree. Tobio huddled under the blade with the rabbit still in his arms. He slowly opened his eye, but then he heard someone land on the sword. He quickly backed off, "Shit!" He looked at the incredibly tall man with bandages wrapped around his face.

"Tobio get back." Kakashi said standing up and looking up at the man. "I know who you are."

"And I know who you are, Kakashi the Copy Ninja." The ninja turned and glared at everyone in front of him.

"Zabuza Momochi." Kakashi's fingers twitched, ready to move at the drop of a hat.

"They've got you babysitting now Kakashi?" Zabuza said stepping off of the sword and removing it from the tree. "The Ninja that copied over a thousand jutsu."

"Everyone get behind me." Kakashi said holding his arm out. "I'll handle this."

"The Mist has standing orders to kill you on sight." Zabuza said with his head tilted to the side.

"Don't worry, you made it to our Bingo Book too." Kakashi said lifting his headband off of his left eye.

"You're going to show it to me?" Zabuza asked. "I'm flattered." He held his sword in front of himself, ready for whatever attack Kakashi had planned for him. "Kakashi of the Sharingan."

Sasuke's eyes widened in stunned shock as Kakashi opened his left eye and revealed his red eye with the three tomoe. "It can't be." He whispered to himself. After all this time, someone else with the Sharingan was in the village. And he knew, the only people who had the Sharingan had to be Uchiha.

"What's a…" Tobio began before Kakashi charged forward with a kunai at the ready. He dove over Zabuza's sword ready to slice through the man's throat. He was not expecting the swordsman to bring the sword back in front of himself so fast.

"The Sharingan." Sasuke said to himself as the two Jonin fought one another.

"Sasuke?" Sakura asked.

"It's the Kekkei Genkai of my family." Sasuke's fists were balled in rage. "Only the Uchiha are supposed to have those eyes." His chest was on fire, this was new to him but he stopped when he felt an arm on his shoulder.

"Talk to sensei later." Sakura said. Her voice was strong and even. Gone was the little fan girl. In front of Sasuke was a kunoichi of the Hidden Leaf. "Right now we have to stay back and let sensei handle this."

Kakashi leapt back towards the genin as he and Zabuza stared at one another. "What are we gonna do Sensei?" Tobio screamed while clutching the rabbit to his chest. "What if he kills…"

"Tobio!" Kakashi got the boy's attention. "I will not let my comrades die!" He glanced back at his three students. Each of them now had a different look on their faces. Sakura was confident in what he was saying. Right now she would believe him if he said the sky was purple. Tobio seemed to relax slightly at the reassurance, but Sasuke, Sasuke's face was different.

"I will not let my comrades die!" The words rang throughout Sasuke's mind. It wasn't that Kakashi said them, it was that he said them and meant every word of it. Sasuke was looking at a man that was a trained killing machine, and he wouldn't let something die. Itachi was a killing machine just like Kakashi, only he killed nearly everyone he cared about.

That fire was burning in Sasuke's eyes again, and Kakashi couldn't explain it, but that look made him feel proud. He turned back to look at Zabuza, if it wasn't for the mask he would be able to see the grin on the ninja's face. "I've got a specialty Kakashi." Zabuza's voice burned through the air as he raised one of his hands up and held the other in front of his face. "Hidden Mist Jutsu!" He shouted.

All around Team 7 the air grew thick with moisture. "Poison?" Tobio asked.

"No." Kakashi said, his eyes scanning the area around them. He had already lost sight of Zabuza, so now he just had to protect the client, and the genin. "It's just a thick fog."

"Just a thick fog?" Zabuza's voice came from every direction. "This is the jutsu that allows me to kill anyone in my way. So what's it going to be, heart, lungs, throat; any one of these can be used to kill you."

Tobio clutched the rabbit to his chest as he looked around. He couldn't see Zabuza, so he checked behind himself to make sure that Tazuna was still safe. "Sensei!" He screamed.

"What is it?" Kakashi turned on his heel to see Zabuza standing between the entire group.

"You let your guard down Kakashi." Zabuza said before swinging his enormous sword at the group.

Kakashi jumped in front of the blade swing and blocked with two kunai. "I won't let you touch them." He snarled as his red Sharingan glared at Zabuza. Kakashi knew in that moment he had the rogue ninja right where he wanted him. "Get back!" Kakashi shouted before he was pushed away by Zabuza and kicked in the head.

Sakura pulled Tazuna away while Sasuke and Tobio stood in front of them to protect the bridge builder. "C'mon, kick his ass." Tobio whispered as he watched the two jonin fight one another.

The two ninjas ran parallel to one another as they ran towards the water. Zabuza grinned under his mask. Fighting on the water was the worst decision Kakashi could make in this situation. He was a Mist Ninja after all.

They stopped at the exact same time and held their hands up. Their fingers moved in a blur and around them dragons made of water came to life. "No way." Sasuke said to himself. He had read something about a fire version of that jutsu the Uchiha had, but a water one was insane.

To make it crazier, there was no delay between either of them performing the jutsu. It was at the exact same moment. The dragons slammed into one another in a wave of water and mist. Sasuke could see that they were saying something to one another, but he couldn't hear what it was.

Their hands blurred to life once again as the held the same hand sign. Sasuke could see the hesitation on Zabuza's face, and it was that exact moment Kakashi formed the final hand sign. The water around the swordsman started to spin on itself. It dragged him under and flooded the area around the lake. "Get back!" Sasuke shouted to the group causing them to put more distance between themselves and the expert ninjas.

Zabuza slammed into a tree and looked up at Kakashi who was already standing in the branches. "Can, can you see the future?"

"Yes." Kakashi lied, "And this is your last battle." He said as he brandished a kunai. Before he could strike however, three senbon landed inside of Zabuza's neck. His eyes rolled to the back of his head and his body crumpled to the ground.

"What?" Kakashi looked to where the senbon had come from and saw a masked ninja standing on a tree. He recognized the style of mask, "A tracker ninja." He said standing up straight.

"I must thank you." The ninja said dropping from the tree. "I have been tracking him for months now."

"Why is he being tracked?" Tobio asked.

"Attempted assassination." The Tracker said walking over to the body.

"Who?"

"The Mizukage." The tracker turned to look at Kakashi. "I have to take him now. Again, I thank you Leaf Ninja."

Kakashi narrowed his eyes as he covered his left. The Tracker bent down and in a gust of wind he along with Zabuza's corpse was gone. The Jonin turned to look at the others. "Is everyone alright?"

"No injuries." Sasuke said as he took a breath. "Sensei, why do…" He stopped as Kakashi collapsed on the ground in front of him.
