Something strange woke Sasuke at an odd time in the morning; it was still dark out but Sasuke now felt very awake so he flicked a light on to finish reading his scroll.

For a second he glanced over at the blond boy sleeping next to him.

Sasuke wouldn't have leapt out bed any quicker if it had been on fire, "blond?" he thought frantically, "but Naruto is in the next room."

as quickly as he could Sasuke ripped covers off the bed, the blond turned over and woke; same messy hair, same whisker marks on each cheek but there was something different. It was like someone had tried to copy Naruto but made deliberate mistakes.

"wha-sa matter?" the blond mumbled.

"who the hell are you?" Sasuke snarled, snatching up his katana.

Rubbing his big blue eyes the fake Naruto glared at him, "what are you talking about Uchiha?" now that his voice was no longer half asleep Sasuke was beginning to recognise the voice, "it's me you idiot. Midonatio."

and it was true, a blonder and slightly more tanned, Midonatio and it took him a while to realise that his hair was actually blond.

"dammit." Midonatio hissed, "i was hoping this wouldn't happen."

"what? What's happened?" Sasuke demanded, his voice rising.

Midonatio sighed, "first thing, lower your voice." he hissed, "and second my name is not Midonatio. Its Yuki."

"what?" Sasuke said softly.

"Queen Eclipse is not my mother, she brought me up." Midonatio, or now Yuki, began, "you see; Queen Eclipse is a demon and demons can make a baby with just DNA."

"what does this have to do with anything?" Sasuke snapped.

Yuki jumped off the bed to confront the last Uchiha and he saw the same black sun seal on his stomach, "let me finish! When the Fourth Hokage was still training he had two friends. One would turn out to be his furture wife and the other was Queen Eclipse." he took a breath, "when the Fourth and his wife died Queen Eclipse tried to take Naruto but she was denied. After two years she decided to use some blood that her friends had given her to make a baby. Me." finally he locked eyes with Sasuke and smiled.

Sasuke couldn't believe his ears; he had listened to Naruto for years about wishing he had a sibling and now, here he was, a living relative of Naruto.

"so, you've got the same father?" Sasuke finally asked.

Yuki rolled his eyes, "Naruto and I have the same parents. Both of them." Yuki explained again.

Sasuke sat down and rubbed his temples, "is that why you're here?" he glanced at the blond boy, "to meet Naruto."

"yeah. I was promised by everyone that by the time I was old enough I would get to meet him and then Sai came to work for Queen Eclipse." Yuki said quickly and yawned greatly.

Sasuke stiffened slightly, "Sai?"

"He told me all about my big brother and I couldn't wait any more to meet him." Yuki began to play with his hair and suddenly looked very much like Naruto, "so I dyed my hair black, covered my markings and faked my powers so I could get to know him without him getting emotional."

"my head hurts." Sasuke mumbled and lay back on the bed; it had been so much information in such a short amount time, "how come your disguise came off then?"

Yuki lay down next to Sasuke, "well, unlike Naruto, I was actually born with Kyuubi and sometimes the charka becomes too much and it will burn away anything bad on me. Namely my disguise." he laughed lightly, "if I were to use him then it would happen in front of your eyes."

so that had been what had woken Sasuke, the sudden activity of charka.
