(Me: I'm going to start saying people's names the Japanese style, last name, then first name. Just a note so its not confusing in the future.-Shiko's full name will be said: Uchiha Shiko. Mmmkay, glad I got that cleared up)

Tobi's expression changed under his mask, but was not visible to the others.
"Wh-what do you mean something's wrong, Yuri-chan?" he asked in his Tobi voice, feeling very panicked.
Yuri squinted, analyzing Shiko again.
"It's kind of complicated, Tobi," she said. "First, from the extraction, Shiko's chakra level is dangerously low. It also appears that a strange energy, probably from the extraction as well, is formed in her brain. Her temperature is also much higher than it should be-she's burning with fever.
Madara struggled to keep his voice from changing from his "Tobi" pitch, the worrying about Shiko sending him into a frantic state.
"YURI-CHAAAAAN!" He wailed. "PLEASE MAKE SURE SHIKO-CHAN IS ALRIGHT!" With that, no longer being able to take the sight of Shiko without loosing his cover, he rushed out of the room, heading over to the cave where captain Yamato was still lying unconious.
Yuri and Sheena quickly rushed to help Shiko. Sheena was donating some of her chakra to Shiko, to help with the low chakra levels inside of her body. Yuri put a cold, wet cloth on Shiko's head, and used her second Kekkei-Genkai, other than the Byakuguan.
This one had come from her father, and was known as the Zenkai.
Yuri lifted up her hands, and as she did water was pulled out of the air, trailing behind them softly.
The water then started to glow, and Yuri manipulated it so that it touched Shiko's pressure points, gently cooling, healing, and putting chakra into these areas.
Rina was gently putting an IV needle into Shiko's arm.
About an hour later, the trio had managed to get Shiko into a stable condition, at least, for now.

Sheena still looked worried about Shiko, and it was for more reason than one.
You might never guess it without seeing both Sheena and Shiko, but there was a special bond between the two of them.
You see, Sheena was Shiko's sister. Identical twin, to be more precise.
They shared all the same traits-long, white hair, pale skin, vampire-like fangs-except for one-the permanent Sharingan that Shiko had been born with.
Now, you might ask. How is Sheena still alive?
When Shiko and Sheena were 18 years old, a clan that specialized in medical jutsu had captured and experimented on a Jutsu that was supposed to make it's user immortal. It worked-partially.
Shiko and Sheena never aged a day after that.
Yuri and Rina noticed how Sheena was unusually quiet, something that was very rare for her.
When they were finished tending to Shiko's needs at the moment, all three of them walked into the courtyard of the hideout to get some fresh air.
Again, Yuri and Rina noticed how unusually quiet Sheena was being.
They stood in the middle of the courtyard, loungeing before a huge sakura blossom tree. The air was not moved by any sort of conversation, they just relaxed, in total silence. It remained that way for a few minutes.
At last, the silence was broken by Sheena, whose eyes were filled with usually unpresent emotion.
"It's been a hundred and five years," she whispered. "105 years since I've seen my sister, Uchiha Shiko."
Yuri looked at her sympathetically. "What is she like?" she asked, curious about Shiko, but not wanting to accidentally hurt her feelings somehow.
Sheena grinned. "Well, she had a bit of personality changes throughout her life...I think mainly because of Uchiha Madara. Supposedly, she died in battle trying to save him before he died." She paused, before adding, "Sadly, her efforts were in vain...Madara was still killed in battle by Senju Hashirama, the first hokage."

"Wow, she must have been very devoted," Yuri murmered.
Sheena shook her head. "She was...but I don't think Madara deserved her."
"But anyways, she gets a second chance at life now," Sheena added.
"Anyways, if you want to know about Shiko personality-wise, I have to tell you, she had a rather split personality. She was very kind, and gentle, but if you awakened her 'dark' side, she could put you through hell. She was also very protective, and wise."
"Sounds a little bit like Zetsu, with his two sides," Rina said, earning a laugh from Sheena and Yuri.
"Yeah, I guess," replied Sheena, giggling.
As she opened her mouth to say more, Tobi suddenly came running towards them, yelling, "SHIKO-CHAN'S AWAKE! SHE'S AWAKE! Quick, follow Tobi to Shiko's room!"
Yuri, Rina, and Sheena quickly sprang up from their sitting positions around the Sakura tree and made their way to the room where Shiko was.
Sure enough, her eyes were starting to open and close slowly, and her breathing became more regular.
Yuri, examining Shiko's health again, shone a medical flashlight into her eyes.
After a few seconds of this, Shiko's eyes closed, and she spoke for the first time since her spirit had been freed.
"Get...the fucking light...out...of my face..." she rasped, her voice barely audible.
Under his mask, Madara grinned. After 105 years of being sealed away, the first thing Shiko had said was to get the examiner's light out of her face, in a rather rude way too. Well, that just showed, her personality had remained with her for all those years.
After the others had left the room, Madara took off his mask, and stroke the face of the now-sleeping Shiko.
"Shiko," he whispered. "I'm here, Shiko."
