Fox took a shower and looked at his image on the mirror as he talked to himself. "Calm down, Fox. She may be awake but she can't move yet. She'll never leave you. You will never be alone. You still have her."

He washed his face and said to himself, "Wake up Fox, she's not yours, someone owns her, she belongs to some family. She'll look for them anytime soon. You have to gave her up soon. You'll be alone again. Just like in the past before Kabuto found you. She will abandon you like how your real dad left you. She will leave you because you are not special. You're annoying.. You are nobody to her. She will never love a nobody like you."

He punch the mirror and it broke. "She is nothing like my dad. She will be thankful to me since I took care of her. She will not leave me. She will love me like a family. She will love me like how I love her." he convinced himself with finality.

"You got yourself a perfect Christmas cake sir!" the delivery boy said as he gave the cake to  Fox. "Enjoy it with your love ones sir. Merry Christmas"

"Yes, I will. My sister just got back to life and she will be happy to blow a cake like it's her first birthday again." Fox gladly replied and gave the payment. "Thank you very much and Merry Christmas."

Fox went back to the room singing a Christmas song bringing a bottle of champagne and a cake.

🎶My idea of a perfect Christmas..
is to spend it with you..
in a party or dinner for two... 🎶

"Tada! I'm back Sarada. I brought a Christmas cake." he said excitedly as he entered the room. But his excitement was gone when he saw no one on the bed. He was stunned when he saw Sarada standing in front of him as she snatched the cake from his hand.

"Should I blow this candle light off or blow a fireball?" she smiled cunningly.

"Merry Christmas Fox!"

Sarada punched him on the face which made him flew few meters away from where he was standing.

"That one is for trying to kill me and making me a lab rat!"

Fox dropped the champagne on the floor and his face was full of fear. He sat on the floor like his spirit left him. He heard the voice from his head saying:

Now that she's well she will leave you. 

she will surely leave you.. 

she will leave you... 

leave you... 

you...

"Nooooooooooooo!" he covered his ears and cried like crazy.

Sarada wondered why he reacted that way. Her heart felt broken by the way he cried and she felt guilty and remorseful for punching him.

She reached out to Fox, touching his head, then she cupped his face and asked him.

"What's happening to you Fox? Why are you crying like that? I'm sorry ok. I hated you for what you did to me but I am also indebted to you for saving me from the mob and taking care of me."

He continued to cry like a baby. So she felt compelled to comfort her.

"Look at me, aren't you happy that I am back to normal? But not that normal, I'm a still blind though."

"You will leave me now right?" he stopped crying and asked.

"Definitely, I have my own family and friends.. I will leave you as soon as I am done asking you questions." she answered honestly.

Fox hugged her like a baby cleaving on his mommy. "You're my only family now Sarada. Don't leave me... Please don't leave me."

"Get off me kid! I am not your mom. I am your lab rat. Did you forget?" Sarada pushed him away since she was afraid of his being clingy to her.

He was in wroth as he weave a hand sign and executed  "Ice prison no jutsu!"

He imprisoned  Sarada's body with a thick ice block up to her neck.

"Now you can't leave me."

She felt cold and helpless again. Her body can't move again just like when she was in a coma, but worst because she can't move her hand to make a hand sign and execute a jutsu. It's a drag, I can't  blow a fireball without a hand sign.

"Set me free you psycho!" she demanded.

"I am sorry sis. I will never let you go unless you promise me you'll never leave me." he said.

"Ok I promise I will not leave you. Just let me go. You treat me like your sister right. Ok I will treat you like my brother. Since I am your sister, I demand you respect my will and let me out of this ice block." she tried to manipulate him.

"I am not yet convinced. You sound like you're lying to me." he said. "Let's just be like this until I am sure you ain't fooling me."

She surrendered and relaxed herself. "Ok fine. Let's just talk then. I got a lot of questions from you."

"What are those?" he asked.

"First, tell me about you." she inquired.

"Fifteen years ago when I was five, I was abandoned by my real father because he said I am a curse. I possess a kekkei genkai which enables me to make ice. I killed my mother and everyone in the delivery room when I was born. I froze everyone in the room as soon as I was born. My father saw it but he was in denial and he can't believe it was me since I was just a baby. So he still took care of me.  But when I was five, he saw me killed my older sister with the ice block. So he hated me and abandoned me." He said coldly in a poker face.

"I don't believe you would kill your own sister. I can see how you long for her the way you treat me. It was just an accident right? How can a five year-old boy know how to wield a power unsupervised? you did't mean for it to happen right?" she remarked.

"Yes. It was an accident. My sister and I were playing but she fell off the cliff. My instinct reacted to it by freezing her so she wouldn't fall. But I didn't know how to undo it so she died being suffocated. But my dad only saw me freezing her. So he concluded I killed her." he smirked.

"I'm sorry to hear that Fox. I can be your sister if you want to." she offered with sincerity.

"Thank you sis." he smiled like a little boy happy to get a candy.

"You're welcome little bro." Sarada smiled too.

"Hey! why call me little? I am taller than you." he whined.

"But you are younger than me. I calculated your age based on your story, you are just 20 years old.  I am 25! So I am big sis and you are little bro understand?!" she insisted.

"Ok, ok, you win!" he giggled and they both laugh.

He undo the jutsu and Sarada was free from the ice prison. He hugged her tight and cried. "Thank you for coming back to life sis."

She pat his back "Hush now. Big sis is here."

They started to trust each other and they both felt comfortable with each other.

"Ok, what's your next question?" he asked.

"Bro, you knew who  I was from the start, tell me did you really plan to make me your lab rat that's why you helped me from the mob at the grocery store?" she clarified his motives.

"My adoptive father Kabuto started the experiment with his mentor Orochimaru many years ago. But Orochimaru, dropped the experiment and concluded it's useless because the Uchiha blood alone cannot completely bring them success. When Kabuto found me, he said I was born special, he made me understood what I am and what I am capable of.  He taught me about science and ninjutsu. Then he taught me about the experiment they abandoned. He and I have been experimenting on something for many years already. He said, we needed an Uchiha DNA plus my DNA to complete our experiment."

"So that's why you sought me and purposely kidnapped me." she snapped.

"Uhm... I am sorry sis." he apologized coyly.

"So what is this experiment about? Why do you need an Uchiha?" she asked curiously.

"You see an Uchiha is able to generate fireball when you weave a hand sign. While I am able to create an ice." he opened the window from the room.

"Combining our DNA, we'll be able to create those species to change the world."  He looked at his creation, smirked and thought.
It's a perfect combination.
