"Revenge at last!" The old woman leaped into the air. Kai instantly got defensive. She usually respects her elders, but this woman was giving her reason not too. Seeing that Naruto was reacting, Kai vanished and appeared in front of Kakashi. Naruto caught the lady's fist with his hands, and his shadow clone (which Kai didn't see him make) disappeared as he met each fist.

The lady had Naruto almost matched. Kai was surprised. "What do you think you're doing, attacking Kakashi-sensei like that, you wrinkly old prune?"

"Naruto!" Kai said. Naruto ignored her. His clone disappeared.

"I haven't forgotten what you did. I've waited for this day White Fang of the Leaf, the day I wreak vengeance on you for what you did to my son." The lady said.

"Wait." Kai said, relaxing her position. "White Fang?"

"No, no, no, you see, I'm not-" Kakashi tried to explain.

"That's enough talk." The lady said. She went to raise her hands but the older man in the room raised his arm. Kai turned to Kakashi.

"Isn't that…?" He gave her a glance that said not now. Kai nodded slightly.

"Take a closer look at the man, sis." The old man said. Kai moved away and went back to her spot. Kakashi laughed nervously. "It's true there's a resemblance, but this one is not the White Fang."

"Hello." Kakashi said nervously, raising his hand in a wave.

"Besides, as you know, the White Fang of the Leaf died long ago." The old man continued. "Remember? When you heard the news, you wept in frustration because it meant you would never have your vengeance. Isn't that so, sis?"

The old lady's brow furrowed as she thought about what her brother was saying. Her voice changed suddenly ."Oh well, never mind." She sang. She then began laughing awkwardly. Kai watched and rolled her eyes before looking back at the paper.

Kankuro interrupted them with a roar of pain. "Here, let me take a look at him." Sakura said, throwing her hair up in a ponytail. "Listen, it might help if you all clear out, give us some room. Kai, you stay."

"Yes ma'am." Kai said, not looking up.

"You got it Sakura." Naruto said. He turned and walked out with Kakashi. The man and old lady followed. Sakura began examining Kankuro as Temari stood and watched, worried. Kai held her head, trying to figure out the poison. One of the doctors came over.

"We tried everything, nothing works." They said. Kai nodded slightly.

"I swear I've seen this before, just give me a minute." She answered. The doctor seemed surprised, but didn't question it. He went back to Sakura, who seemed to be of the most concern.

"What are you, who are you?" The one asked.

"I'm a leaf village medical ninja." She answered strongly. Kai grinned. She put her head to Kankuro's chest. "We're definitely dealing with a heavy metal based toxin, the kind that attacks muscle tissue, destroying the cells integrity."

"You were able to learn all that, in one look?" The doctors said in awe.

"May I see his chart?" Sakura asked. Kai handed it to her, since she had it.

"We were getting a breakdown of the poison, but there are still quite a few blanks…" The doctor said.

"I know just what will happen." Sakura said while reading. "The cardiac muscle will be weakened, to the point where the heart will collapse, and cease functioning altogether. It's doubtful we'll be able to come up with an antidote in time. Unless…" Sakura looked at Kai. Kai shook her head.

"What are you saying, there's nothing you can do?" Temari said exasperated.

"I'm going to need a few things, and I'll need them quickly." Sakura said.

"Right." The doctors said, straightening.

"This is going to be pretty crude, but it's the only option we have." Sakura said. Kai narrowed her eyes, staring at the wall. The words Sakura said… they were starting to jog a memory.

"Sakura, I might know an antidote…" Kai said. Sakura looked up.

"Really?" She said. "What is it?"

"Here's the thing, it takes three days to make." Kai said. Sakura looked defeated.

"That won't help us. We'll stick to my plan." Sakura said.

"Yes, of course." Kai answered. The doctors came back with what Sakura needed. They set up and Kai went to the side.

"Hold him down and don't let him move." Sakura said, rinsing her hands in this water like substance. "This part of the procedure is not going to be easy for him."

"Got it." Everyone said. Kai took to a spot to help hold him down. Sakura manipulated the liquid to form a ball in her hand. She concentrated, putting it on Kankuro.

"Here goes." She said. Kankuro screamed, sitting up. "Hold him down!" Sakura cried. He fell back and she began with the procedure. Kai watched in awe. She was taking the toxin directly from his body.

"What's that, is that the poison?" Temari asked.

"That's it!" Sakura said. She dropped the solution into the pan. "Another." She said.

"Right!" The doctors said, and made another pan of the liquid.

Sakura worked tirelessly to extract all the poison. She pinpointed each major organ. After what seemed like hours, she breathed a sigh of relief. "I removed most of the poison. I believe that ought to put him out of any immediate danger." Everyone sighed with relief. The ones waiting outside came in.

"Way to go Sakura!" Naruto said.

Temari backed up and slid down against the wall. She seemed exhausted.

"But he's not completely out of the woods yet. Now then, Kai let's make that antidote. There are traces of toxin still in his body." Sakura continued.

"I see. Anything you need, don't hesitate to ask." Baki responded. \

"Well, I'll need a list of all the medicinal herbs that you have in this village." Sakura said. Kai walked up to her.

"I wrote down which ones we'll need, and we can substitute as needed." Kai said.

"Yes at once." One of the doctors said, walking away.

"And we should change these bandages for new ones." Sakura kept going.

"Yes, ma'am." Another doctor said.

"I'll need an IV drip set up, stat. Oh, and be sure to set aside a small amount of the toxin I extracted. I'll be needing it later." Sakura said finally. Kai smiled, proud of Sakura. She knew just how hard her teammate had been working. Kai assisted with the Nurse on setting up the IV drip.

"You remind me of the old slug queen Tsunade. Isn't it strange you turning up in our village like this?" The old lady, Chiyo, said.

"Well, after all, Lady Tsunade is my teacher." Sakura said proudly. "And it was by her order that I personally came here."

"Here's that list of medicinal herbs." One of the nurses walked towards Sakura and handed it to her. Kai looked over her shoulder.

"Good, thank you very much." Sakura said taking it. Kai pointed out the few herbs they could use. Sakura nodded smiling. They went and made the antidote together in the greenhouse.

"I never thought I'd find such a wide variety of medicinal herbs here in the hidden sand." Sakura said. Kai nodded slightly, helping one of the nurses pick the herbs.

"Well, we try." One of the nurses responded. "Our soil's not very well suited to growing them. We can't grow much scurvy grass, for example.

"That's alright, there's enough. I can make three doses of antidote." Sakura said. Kai and Sakura shared a smile before going back to work.

It was nightfall before they had finished. Sakura took some of the antidote and tested in on a scroll with the poison. Everyone watched closely as the antidote worked with the poison. There was a sizzle and then the scroll was clean.

"It worked! It's ready!" Sakura said, beeming. Kai grinned, thankful that their hard work payed off.

The two girls took the antidote back to the room where Kankuro was. Sakura made a tea

and had Kankuro drink it. Kai stood back by Kakashi. Kankuro finished it and Sakura gave him some instructions for the next few hours. Kai sighed a little, which Kakashi noticed but didn't say anything.

"All of you are going to need rest as well after your journey. We've prepared rooms for you." Baki said.

"But, But we've gotta go after Gaara!" Naruto exclaimed.

"Thanks, we'll take you up on your offer." Kakashi said. Naruto and Baki both turned to Kakashi. "We may have to travel far and fast tomorrow." Naruto pouted a bit.

"Ok, you win." Naruto said quietly. Kai gave Naruto a reassuring look. They gathered their belongings and prepared to leave the hospital to the rooms they were given.

"Naruto." Kankuro said.

"Hm?" Naruto turned to Kankuro.

"Save my little brother, will you?" Kankuro finished.

"Don't worry, I will." Naruto smiled. "After all, I'm gonna be hokage some day, and for not the Kazekage can just owe me one."
