Zabuza was confident he could kill anyone that came near him and his quarry. His quarry being the damned fisherman.

Haku, his right-hand man, sat there with his fake Kiri-nin mask on and ready to follow his orders. He knew the plan - any sensors, he conceal his chakra completely.

He shifted minimally and released Haku's rabbit. The rabbit was a perfect Kawarimi tool.

One of the genin, a blonde with a green headband, looked at the rabbit. "Say, Kiana, how much would the Uzumaki fish?"

Zabuza stood stock still, blood flowing from his face. An Uzumaki. Uzumaki come to get revenge.

He was scared. But he had to do the jutsu.

And kill the damn bridgebuilder. He was nothing without his honor.

But he was also nothing without his life.

He brought Kubikiriboucho up and called up the chakra-mist.

The last of the Uzumakis would die... After the bridgebuilder.

Naruto tensed as she felt the mist creep in.

Your seal.

My seal? She frowned. Then - Ooh. Wow, I can't believe I forgot about that.

Well, it might have been because I knew your mind wasn't fully healed from jumping into a living person's mind, you idiot.

Oh, yeah. I don't really want to go into a coma again. Water jutsu person...

She felt the seal on her back flare as she smirked. "Senju Tobirama!"

She had never blindly threw herself into a person's timeline in the middle of battle, so she would have to rely on Kurama to right her.

Tobirama gazed at his brother. "Stop this foolish notion, brother," he told his older sibling, who was silent. Itama's death had hit him hard, and addled his brother's mind. "The Senju and Uchiha can never get along. This is proof."

"You're wrong!" Hashirama glared at Tobirama. "And I will prove it, I swear it."

He stormed off.

Tobirama followed his brother.

"Hashirama, you cannot prove anything. The Senju and Uchiha are always enemies! Always. That is what it has always been!"

"Well, I will change that!" Hashirama's stubbornness was a trait given to him by their father - his kind of babyish features was their mother shining through, though.

"No, not even you and your idiocy will change anything. They are the enemy, and nothing, not even the power of friendship will help you."

With those words, Tobirama whirled around.

~"~

Seeing the Uchiha and his brother together, Tobirama was enraged. Itama had died because of an Uchiha.

To prove that he could hold a grudge, he began his lifelong fight against Izuna. Izuna seemed to enjoy their fights, to toy with Tobirama.

As Hashirama and Madara fought and were never willing to mortally wound each other, Tobirama couldn't mortally wound Izuna.

They struggled with this. Izuna even caught Tobirama and did his best to break him.

But it was for nothing. Izuna's final death and Tobirama's warning to never trust the Uchiha because he could hold a fucking grudge for his entire fucking life... His warning did nothing. So he, when his brother was dead and Mito locked away by her own will and grief, he moved the world and changed things.

And Sarutobi... He was one of the pupils he had taught firmly, along with Danzou. Two of his brightest pupils.

He went to his death knowing that Sarutobi Hiruzen would succeed him, and his vision against the Uchiha would one day be realized.

Naruto flashed her hands in the symbols for a high-leveled water jutsu, water exploding out of her mouth, dispelling the mist and making them see the person hired to kill Tazuna.

There he was. He looked pissed she'd figured it out, and went after Karin.

A spray of blood later and she was facedown on the ground.

Naruto could barely register Zabuza's movements towards her.

Her eyes hurt as she stared at Karin's barely moving body.

An unearthly scream tore its way from her throat.

Kiana looked shocked.

Naruto could feel hot, thick tears falling down her face. She registered Kakashi's shock - hell, even Asuma's dropped trench knife, but she could only stare at Zabuza in anger.

"You hurt my family."

She could distantly feel Kurama's shock, but she was in the midst of bloodlust. She wanted his death for hurting Karin.

She launched herself towards him, kunai out.

She shoved him to the ground, his arm snapping and dropping his oversized butcher knife. She had the kunai at his neck, but then she recalled Tobirama's past and stumbled off of him, shaking. She looked at her shocked friends and family and a noise, a half-sob and half-scream, came from her body.

She couldn't kill another person.

She couldn't.
