This didn't make sense. How was he supposed to urinate?

Could his body possibly be female?

Sasuke tried to access the memories this body experienced and came up with the same general history he expected—being ignored by his father for his older brother, being comforted by his mother, and eating dinner together with his family while yearning Itachi's attention since getting any from Fugaku was a hopeless cause.

Counting a few annual celebrations—Sasuke estimated that he was 4 years old, and he was about to piss his pants if he didn't learn how to use the toilet—

No, he knew, he just had to sit his butt on the toilet seat—

Sasuke groaned, utterly humiliated.

Do I really have to do this?

His bladder screamed him to piss and Sasuke grit his teeth. Just as he was about to turn, Itachi appeared in front of him.

"Wh-WHAH!" Sasuke yelped, startled as he stumbled backwards against the closed bathroom door. As his back hit the wall, he glanced behind him before looking back fearfully at Itachi—this reminding too much of the last death match he had against Itachi, when he was cornered to a wall about to have his eyeballs ripped out.

When in truth, Itachi forced himself to do all that for Sasuke's benefit.

Sasuke pressed his back against the wall, taking in the confused expression and furrowed brows on his older brother's usually blank face, and couldn't help but grin. "Heh. Nii-san. Heheheh."

Pushing himself off the wall, he leapt forward and hugged the nine-year-old, who was double his height but he didn't care. He missed this moment so much—now that he thought about it, he didn't remember ever hugging anyone in his life. That was to change, Sasuke decided, as he curled his fingers a little tighter around the small of Itachi's back, pressing his face into nii-san's stomach.

And squeezed, as if to confirm all this was reality.

Sasuke loved his brother…but it wasn't love that had fueled his hatred for Konoha.

It was guilt.

Guilt that Itachi was a tool used and exploited by politicians, guilt that Itachi had tried to manipulate Sasuke into exploiting his death—to kill him and return to Konoha with honorary medals and monetary awards, and new eyes.

He labeled his 'guilt' as 'love' because Uchiha Sasuke was never guilty.

He did love Itachi, though, but it wasn't Itachi's sacrifices that made Sasuke love his brother—countless others like Naruto had risked their lives to bring him back to Konoha—he didn't love them.

It was simply because they were brothers, and he couldn't help how he felt.

"Foolish little sister," Itachi finally snapped out of his surprised trance. Sasuke was always affectionate. "For a moment, you acted afraid of me, and now, you're hugging me." He awkwardly patted 'her' back before roughly pushing 'her' off by a mere forehead-poke powered by chakra.

"Ow!" Sasuke's hands flew to his forehead immediately as his butt hit the floor. "Grh. You're always doing that!" Sasuke complained, though he couldn't hide his wistful smile.

Itachi blinked. That…expression…was the same one he had when he was around Sasuke—attempting to appreciate their little family moments to the fullest extent before heading off for a week-long A-rank mission.

But Sasuke was an immature kid, not a veteran shinobi, so why was 'she' acting like an old man?

"Little sister," Itachi began as Sasuke looked up at him with hopeful eyes, "Pull up your pants."

Sasuke's eyes widened as he looked down at his shorts—they were off because he needed to pee, but now he didn't feel the urge to urinate and he noticed his pants were soaked wet.

In other words, he pissed his pants, in front of Itachi.

"Shit! Shit! Shit!" Sasuke panicked as he hopped to his feet. In a flash of speed a 4-year-old shouldn't have, Sasuke was behind Itachi and pushing him out the door he opened in the process. "Get out, nii-san!"

"Profanity at this age? Tsk." Itachi chuckled. "Should you have trouble cleaning up after yourself, I'll call mother."

Sasuke groaned and slammed the bathroom door shut, before propping to the floor.

This was the most humiliating day of my life—

I will never shame myself again.

I have my pride.

Sasuke trembled a bit in embarrassment before gritting his teeth.

If I prevent the Uchiha Massacre, that will make up for all the embarrassment I suffered through today.

Then everyone will forget the events that just occurred because I performed a greater feat.

That sounded stupid and childish, Sasuke realized. Were his toddler hormones beginning to affect him?

He decided to try another thought process.

Itachi called me 'sister.' So I'm female. Tch. As if I care about my gender.

It might even be to my benefit for my plans on saving the clan.

Sasuke walked over to the shower and turned it on, the water splattering down as he stepped underneath it, reminded of the rain.

How am I going to prevent the downfall of my clan? What am I supposed to do, kill Danzo? What, in the middle of Konoha?

And more importantly…Itachi met with 'Madara' before the massacre.

Obito Uchiha was impersonating as Madara.

Sasuke groaned under the showerhead.

He had to deal with Tobi, Danzo (and the elders), and some stupid Clan conflicts before they escalated into a civil war, as a 4-year-old. He calculated he had three years, but his time limit could change depending on what effects he caused.

If I could take every burden off Itachi's shoulders, I would do anything. Absolutely.

Sasuke laughed.

If I'm lucky…'Tobi' hasn't made a move yet.

He who moves first…always wins.
