Adjusting Perceptions.

Izuna was getting really frustrated. He had had all night –well, more like six or seven hours since he had woken up until Mikoto came to look for him– to think things through and he had come to the conclusion that his first thought has been adequate.

This of reincarnation sucked.

Once past the shock of finding himself as a baby and going through the fact that he remembered giving his eyes to his brother, before dying, he had concluded that he had reincarnated. And thanks to the gods that he had been born Uchiha once more, because if he had been born within another clan, like the Senju –forbid the tough!– he would have committed suicide in that same place and time.

However, that was the only thing that could be rescued from his situation as there were so many things wrong that I did not even know how to start.

For one, he was a baby.

Yes, physically he was a two-year-old boy. And if that was not bad enough, ´Sasuke´ was a spoiled brat that the only exercise he did was play. Yes, play. Where had been left the basic katas of taijutsu of the clan? And the conditioning to create stamina? And the exercises to learn to control your chakra? How was he supposed to grow and became an able shinobi if he wasn't being educated in the basic arts of the clan?

In second, but in relation to reasons above.

Everything he had gotten from blood and sweat was gone!

His sharingan, his ability as a sensor, his mastery in the art of the sword, his perfect handling of the elements Fire, Air, and Thunder; everything was gone. "Thunder not Izuna" was not going to return. Not even if he trained to death as it was very unlikely that he shared an elemental affinity with Sasuke beyond the characteristic fire of the Uchiha.

But worst of all was that he was surrounded by impostors who pretend to be his family.

Mikoto Uchiha was a beautifully gentle and motherly woman, she called herself Okaa-san. She was not; His mother had been a fierce, but beautiful warrior, Uchiha Naomi, nee, Uzumaki. Hence his affinity to the air, thanks to the sky that was the only thing he had inherited from her. –Do not misunderstand him, he deeply loved his mother, but it would have been terrible to inherit his fire-red hair like his little sister Suzune or that horrid tic talk like his brother Deisuke.

Naomi had been a great mother and Mikoto could never replace her.

Fugaku Uchiha was not his Otou-san. Even if they were very similar in personality. Which instead of helping Fugaku, it harmed him, because by the time of his death Izuna had hated Tajima Uchiha. And that had not changed now that he was a baby.

Tajima had not been a great father. What's more, he had been the kind of father who sees his children as weapons, but it was fine. That was usual in the war era.

He had not loved his children and they had not loved him either.

However, Tajima and his way of educating was the reason why he had managed to survive on the battlefield even when his brothers did not. He was the one who had led him to become strong and who had taught him what it means to be an Uchiha.

For all that, Tajima Uchiha was his father and Fugaku could never take his place.

And finally, there was Itachi.

Uchiha Itachi was the one who distrusted and resented the most. How dare he try to take his Madara-nii's place? That was blasphemy! There was no one – no one– who could take his place in the heart of Izuna.

For that reason, Izuna saw with suspicion the six-year-old boy who moved a stuffed dinosaur trying to make him laugh. Sasuke had always been an easy laugh and don't get a reaction from him was apparently stressing and worrying the older raven.

At any other time he would have felt bad, after all, he had always had a weakness for children and would surely have laughed and gurgled happily for the other. But at the moment, the least he wanted was to be near the blasphemer.

Unfortunately, he did not have another choice because Itachi was very stubborn and so Izuna had found that there was nothing he could do. His current form limited his movements, so trying to escape turned out to be stupid and unsuccessful because he was caught in seconds and making a tantrum did not work either because instead of frightening Itachi it seemed to increase his desire to be close and carry him.

So he was content to sit down and throw bad looks at the other boy, with his little arms crossed and the irritation very clear in his eyes, a scowl adorning his features.

They had been almost two hours doing this, at some point Itachi was going to tire and was going to leave him alone. Izuna was a patient –and stubborn– person, so he could wait. He was not going to lose against the usurper.

"Oh, come to Otouto. What do I need to do to make you smile?"

Leave me alone. The scathing answer came to his mind instantly, but he did not say it out loud. Mainly because Itachi had tried everything he could think of to improve his mood since they finished breakfast (Two hours ago) and had even skipped the academy just to be with him, which would surely put him in trouble with both his parents and his teachers and so Izuna had to recognize the effort. But above all, because he had an expression of misery that could break anyone's heart. It was really affecting him not being able to make him laugh.

Maybe if he laughed...

No. No. That would accept defeat and Uchiha Izuna cannot afford to lose against a child. Out of respect for Madara-nii, he could not accept the other black-haired boy as his brother.

But…

But he looks at me in the same way that Madara-nii used to. As if I was the most important thing in the world ... as if I was his entire world.

That conclusion made him bite his lower lip in indecision. Izuna had had four brothers and a little sister. He had loved them all in the same way, absolutely and unconditionally.

The war had taken four of them. The Senju had snatched his sister Suzune and his mother from this earth. And so Madara-nii had become the only thing he had left, in no time his only remaining brother became without a doubt the person he loved the most and his happiness became much more important than anything else.

For this reason he did not use his Mangekyo Sharingan to kill Tobirama on the battlefield, because that would destroy Hashirama and see Hashirama hurt, would had made his brother fell sorrow; And for the same reason on his deathbed he pulled out his own eyes and offered them to him, because he could not let his brother lose his sight.

Itachi could not replace Madara.

But maybe he did not have to. Itachi could have his own space in his heart and Izuna (Sasuke) could love him as he had loved his other brothers.

It was an acceptable compromise.

He smiled and spread his arms in the universal sign of ´I want you to carry me´. Itachi sighed in relief and sketching his own smile lifted him, hugging him and making him feel safe, one of his brother's hands began to caress his hair in a loving way.

"I love you, Nii-san" Izuna murmured before depositing a thunderous and wet kiss (very characteristic of the age he appeared to have) on the older raven's cheek.

"I love you too, Sasuke"

Those words made the situation a little better. And while it still stunk to be a baby, everything else had a solution.

Maybe this second life was not so bad after all.

OoOoOoO

Itachi was not a fool. He knew something had changed.

Sasuke had never been a sullen child. Actually, it was the opposite. His little brother loved to laugh, sing and play…and it had always been easy for Itachi to make him smile. Furthermore, Sasuke had never shied away from his touch. He had never refused a hug or to be charged, as he had already said, it used to be basically the opposite.

But above all, his Otouto did not have eyes like those that had received him in the dining room during breakfast. Those were cold, analytical eyes. Like those of a shinobi on the battlefield, they studied everything around him in search of a threat. They watched the movements of their parents and his own, like his little brother was worried that he would be attacked by the member of his own family.

Those eyes changed as breakfast passed, seeming to relax when he found that he was not in danger.

Those same eyes had looked at him with suspicion and something very close to contempt when he had tried to carry him. They had looked at him, full of irritation, the two hours he spent doing everything that went through his mind to make his little brother laugh.

Those eyes shone and were sweetened when their owner seemed to reach a conclusion, before smiling and asking to be lifted.

Those were the eyes of an adult, not those of a two-year-old child. And yet, they looked exactly like his Otouto when the little boy declared his love.

So, yes. Itachi knew that something had changed, but he did not care.

Sasuke would always be his little brother.

And he would love him no matter what.

OoOoOoO

That day marked the beginning of a new chapter in history.

That day two brothers created a bond of love that would change the destiny that awaited them both.

That day two parents lost their youngest child without realizing it.

Thank you for the revies!

Ahuvati: As always, I love hearing about you! I actually made some little changes in the chapter's so it actually it will be more in this history than the one in Spanish. But in the end, the plot is the same. Just a little more concrete in some aspects.

Merendinoeliano: Glad you like it :3

Sychonicity911: Yes, well. When I was first thinking about this plot I realized that Izuna and Sasuke are very similar in appearance and that they could practically be twins! And well, Kishimoto has sold us the idea of the reincarnation and transmutation of the soul. So I got to thinking what would happen if Sasuke were not the reincarnation of Madara, if not Izuna? And if in addition to that he retained the memories of his previous life?

And that became this history, so to answer to question yes that is the reason they look the same.
