Hehe, I finally got around to finishing this chapter! Aaand it happens to be the longest chapter I've made in my life! :D

Right, I've been really busy with other things, and writer's block was getting to me. The only Japanese in the chapter is something I've taken to saying! It's hare ta, and I might as well go ahead and tell you what it means! It means 'Fine' and I really like saying it, and it's even better when you say it twice! Oh yeah, and my little brother taught me that I have WordPad on my laptop! Anyway, here's the chapter that I've been working on FOREVER!

The next few days were like heaven to Sarah. She started caring about what went on around her. She looked like she was sane again, and she was cheerful no matter what. She spend most of her time with her mother, whether doing something fun or just sitting together and talking. She became a girl you couldn't make sad if you tried. Sarah didn't walk anywhere anymore. She danced where she wanted to go. Her eyes shimmered nonstop, and the turtles were relieved. They were glad she had stopped being insane like she had been before. Akita was just as joyful as Sarah, only Akita didn't live with Sarah and the turtles in the sewer. She rented an apartment as soon as she had come to New York. The rent lasted a month, and Akita figured it would be a waste to move out now. The entire atmosphere was bright when either Sarah, Akita, or Candy was in the room. She stood beside Mikey as the funny one in the house, and Raph teased that Sarah was taking Mikey's roll. One night, the night before Sarah's fourteenth birthday, Sarah was extremely hyperactive. She paced all through the house, trying to find something to do. Finally she decided to go out.

"Master Splinter! I'm going out for a while!" she called, and Mikey hopped off the couch.

"Mind if I come with you?" he asked, and Sarah blushed.

"Sure, let's go." she said and bounded out of the room and into the sewer. Mikey wasn't too sure what movement Sarah was doing, but he DID know that it was spinny and jumpy. He laughed and ran to catch up with her. Once they were at an exit to the dark tunnel, Sarah practically flew out into the city. In the blink of an eye, she was up on the fire escape and climbing onto the very building that her mom lived in. By the time Mikey was on the roof, Sarah was up and running in circles.

"Hyperactive? What brought that on?" Mikey laughed again, and Sarah skid to a halt in front of him.

"I dunno. It just happened I guess." was her response, and she ran around in circles again. Mikey watched in amusement as Sarah circled the roof over and over. Finally she slowed down and swayed slightly.

"Woah, dizzy!" she said, sitting down on the edge of the building. Mikey walked over and sat down next to her.

"It's my birthday tomorrow." Sarah said, starting a conversation.

"Uh huh." Mikey replied, distracted.

"Hey Mikey, I wanted to thank you." Sarah said, turning to him.

"For?" he asked, glancing at her.

"Getting through to me. If it wasn't for you, I wouldn't have turned around. I would have kept on walking." she said, smiling.

"Sure you would have turned around." Mikey responded, not so sure of that himself.

"No, I wouldn't have. I would have gone all the way to Japan." Sarah whispered, then looked back out to the city.

"The city sure is beautiful at night, don't you agree?" she said pleasantly, watching the lights intently.

"Yeah....beautiful..." Mikey said softly. But he wasn't looking at the city in front of them. No, his eyes were on Sarah. Then Sarah's eyes darted over to him and he quickly looked back out to the buildings before them. Sarah smiled and blushed again.

"I wonder what the rest of the world is doing tonight." she whispered, staring off into the distance. Probably nothing like what I'm doing, she thought. She leaned back and rested her hands against the roof behind her, looking up at the starless sky. She started humming the first song that came to her mind, a Japanese one. Her eyelids drooped and she sighed. It was so warm out today. She shook her head and tried to resist the unbelievable urge to fall asleep. Why was she so sleepy tonight? It was no different than any other day. Mikey looked over at her and smiled.

"Tired? Maybe we should go back home." he said and Sarah nodded. Then she closed her eyes and frowned.

"Carry me." she demanded and felt herself blacking out. The last thing she felt was being lifted up before she fell asleep.

~The next day~

Sarah woke up with a start in her bed the next morning. She rubbed her head and tried to remember what happened. Let's see. She was up on her mom's apartment building with Mikey. She started humming and then she fell asleep? Yeah, that summed it up pretty well. She glanced at her calander and grinned. Today she was officially fourteen. Her mom always went over board with parties, so Sarah was actually a little afraid. She stood up and looked at her reflection in the mirror. Beautiful. She walked hesitantly out of her room and checked to make sure the coast was clear. Very slowly, she made her way to the kitchen. She closed her eyes and waited. And in five, four, three, two, one...Just as she hit one, Akita threw her arms around Sarah.

"Happy birthday Sarah!" she cried and Sarah winced. Why did this always happen? Not that she wasn't happy, but this was extreme. The one thing she dislike about the large birthday parties was the beginning. They always simmered down towards the end though. Then she decided to give in and hugged her mom back. If there was one thing Akita liked more than being a doctor, it was her own daughter's happiness.

"Come on, into the kitchen!" Akita said, pulling Sarah gently. It, for once, was a simple party. Probably because it would be harder to throw a bigger one in the current situation, despite the fact that Akita and Sarah were excepted on the streets. Sarah, for her mom's sake, acted like you would expect a child to act. She threw her arms in the air and laughed.

"Surprise!" she said to nobody in particular. Akita didn't want to accept the fact that Sarah was growing up, so Sarah didn't act any older. That and Sarah found it easier to act childish than to be mature.

"I didn't have much time to get a party put together, but I managed." Akita said, and Sarah noticed how tired her mom looked.

"Oh Mom, you didn't have to-" Sarah started to say, but Akita cut her short.

"Yes, I did. I didn't pay enough attention to you before, and you ran away. I don't want that to happen again." she whispered, and Akita and Sarah's yellow eyes met and locked. Sarah tried to find something in Akita's face, but couldn't find it. She walked up to her mom to whisper something to her.

"Can I have some cake now?" she asked quietly, and Akita laughed.

"Not yet Sarah. Wait until later. Oh! And I did manage to find this for you." Akita said, giving Sarah a small present. Curious, Sarah ripped off the wrapping paper and pulled out a box, which she opened. Inside there was a small music player. Akita knew Sarah loved music, it wasn't hard to tell. Sarah's eyes shined as she looked at the tiny device. The fact that it was from her mom made it even more special.

"Must...listen to...MUSIC!" Sarah cried, making everyone laugh. Her eyes darted back over to the cake that looked new and her stomach rumbled.

"Are you sure I can't have cake yet?" she begged, but Akita was firm.

"A little bit of waiting won't kill you!" Akita said, smiling at her daughter.

"Well, I'm hungry, so it just might." Sarah answered, looking sadly at the delicious chocolate cake sitting in the kitchen. It was teasing her.

"Sarah, why don't you eat breakfast instead?" Akita hinted, shaking her head.

"Hare ta, hare ta!" Sarah gave in, stumbling into the kitchen, a mischievous grin on her face.

"Sarah, if you touch that cake, you'd better be halfway out of New York by the time I walk in there!" Akita threatened playfully, and Sarah stopped.

"What makes you think I would touch the cake Mom?" Sarah said innocently, not turning around.

"I know you Sarah, you aren't very patient." Akita frowned. Sarah disappeared into the kitchen.

"I'm touching the cake! I'm touching the cake!" she called out into the living room and Akita rolled her eyes.

"One problem with that Sarah! That cake isn't a cake. It's mud!" Akita couldn't hold back the grin on her face. Sarah was gullible sometimes.

"Then why is it so tasty?" Sarah shot back and Akita ran into the kitchen with her.

"Don't worry guys! The cake is fine!" Akita called, and everyone else laughed again. They walked back into the living room, Akita leading Sarah. The next few hours flew by. Sarah managed to put some music on the music player her mom gave her, then settled on the couch to listen to it. Akita guarded the cake while pacing. At about 5 p.m., Akita walked back into the living room.

"Mikey, can you come here?" she called, and Mikey ran over to her.

"Yes?" he asked.

"This may sound silly, but can you watch the cake? I have to get something I forgot at my house and I don't want Sarah getting to it." Akita said, her eyes on Sarah, who was off in her own world on the couch.

"Yeah, sure." Mikey said. "I'll make sure she doesn't get the cake."

"Thanks. I'll be back shortly." And with that, Akita headed out into the sewer to go to her apartment and Mikey took over her position as cake guardian. And of course, he had to resist eating the cake himself. It DID look delicious...No, he couldn't eat it. He snapped back to attention when he saw Sarah sneaking into the kitchen. He hid behind the counter out of her sight. He grinned and watched Sarah's hand reach slowly up to the counter. When her hand was just a few inches from the chocolatey goodness, Mikey sprang up and grabbed her wrist.

"Ah!" Sarah screamed, startled. Then she frowned. "And I thought I had it that time...Now could you let go?" She snatched her hand back.

"You're not getting this cake Sarah." Mikey said, and Sarah grinned.

"You were thinking about eating the cake, weren't you Mikey? she asked.

"N-no! I was not thinking about eating this delicious double layer chocolate cake!" Mikey protested, his eyes darting back to the cake.

"I will give you twenty dollars if you give me a piece of that cake." Sarah got on her knees and begged.

"As much as we want this cake, your mom would kill us." Mikey reminded, and Sarah ran that through her mind.

"I am willing to take that chance!" she said desperately. Unfortunately for them, Akita walked in just then. Sarah and Mikey ran to greet her.

"Where'd you go Mom?" Sarah asked, but Akita didn't respond. Her eyes were wide and her face was pale. "Mom, what's wrong?"

"Uh...Sarah? Can I talk to you in your room for a minute?" Akita stammered and Sarah frowned.

"Sure, let's go..." she said, confused. The turtles and Candy waited for them to come back.

"What do you think that was about?" Candy asked.

"I don't know. But it must be bad for Akita to-" Leo began to say, but was cut off by Sarah.

"NO!" she screamed from the other room. Everyone jumped at Sarah's outburst, which was followed by Akita's frantic words.

"Sarah, calm down! Please Sarah, don't overreact!" she shouted over Sarah's screams of what sounded like agony. Like she was being tortured. Sarah stormed out through the hallway, her eyes a bright red. Akita was chasing after her.

"Sarah! Come back here! You need to calm down before you do something you regret!" she called to the girl, who didn't seem to walk at all. She floated into the kitchen and started pacing. Before Akita could enter the room, she had ran out. Akita groaned and chased after her. Sarah ran out of the kitchen, to the door and out into the sewer before the turtles could react.

"Come on guys, we have to stop her!" Akita said frantically. They jumped up and started to follow her, but stopped for a minute.

"Candy, you stay here. Tell Master Splinter where we are and tell him not to worry. We'll be back!" Leo called and they started to follow Akita again. They ran as fast as they could through the sewer, but Sarah was much faster.

"We have to stop her before she can do anything drastic!" Akita called behind her, and the turtles ran to catch up.

"What happened? What did you say to her!?" Leo wondered, and Akita turned her head slightly.

"It's something that happened back in Japan. Her father....killed her sister..." Akita choked out, then turned her head back to look in front of her.

"She has- er...had a sister?" Leo asked, and Akita nodded.

"Yes, they were twins." Finally, they got to a spot where they could resurface. By the time they had gotten up, there were people lying dead in the street and pools of blood everywhere. People were screaming and running, it was a mess of confusion. But through it all, they could see Sarah. She was sparking with mass amounts of electricity, and she was completely grey. She was whipping her right hand around, and with each time, someone close to her fell dead to the ground.

"Sarah! Stop this NOW!" Akita said fiercely, and Sarah's head snapped up to look furiously at her mother. Sarah bared her teeth, which were remarkably sharp.

"You don't understand! You can never feel what I'm feeling! You don't care about Rachel, you don't care about me!" Sarah shouted over the confusion and she started walking over to Akita. With each step, she grew darker. Finally, she made her way over to Akita. Sarah raised her hand and brought it down hard on Akita's face, knocking her down. Then she spun on her heel and stalked off, heading out of the city. Careful to not be seen, the turtles help Akita into the shadows. She was more frightened then she was before, and there was a large red mark on her cheek.

"I don't care if she hit me, we have to stop her!" Akita insisted, and Leo nodded.

"Come on, let's go." he said and they ran to catch up with Sarah, who was gliding off out of their sight.

"What do you think she's going to do?" Donny asked as they chased after Sarah.

"Chances are she's going back to Japan and causing chaos there. We can't let her do that!" Akita responded, easily keeping up with the turtles.

"Will she really go that far?" Leo wondered, and Akita nodded.

"Yes. She will. There's no doubt of that to me." she said, but then she spotted Sarah, who had stopped for who knows what reason. Sarah turned to look at them.

"Sarah. Stop it!" Akita said to her, but her words bounced off of Sarah.

"Why? What difference would it make?" Sarah shouted angrily, and Akita's expression softened for a minute.

"Sarah, I don't like this any more than you do. But this is extreme!" Akita tried to reason, but Sarah ignored that.

"If you want to stop me, you're going to have to take me down yourselves!" Sarah growled.

"You know I can't do that Sarah." Akita whispered. And it was true. Both pysically and emotionally it was impossible for her to stop Sarah. Akita had even started to think that it was just plain impossible. Sarah laughed, but it wasn't a kind laugh.

"Than you can't prevent me from going to Japan and killing my father!" she said with a finishing note.

"She can't, but we can!" Leo said, and Sarah turned to look at him as if he dare have the nerve to speak up against her.

"I'd LOVE to see you try!" Sarah challenged, and Leo pulled out his katanas.

"Ok then. Let's go!" he said, and Sarah's red eyes flashed. Then she looked at Leo's brothers, who were also wielding their weapons. Sarah grinned and showed them her sharp teeth again. They had the point and sharpness of razor blades.

"This should be interesting. Let's see what you've got. Although from my past experience, I know that isn't much." she taunted, infuriating the turtles. They came at her from different directions, but she easily jumped out of the way. She even took the time to taunt again.

"See? Not much!" she laughed. "Not much at all!" They came at her again and she dodged blades, sticks, and nunchuks.

"Is that honestly all you've got?" she asked, trying to make them mad. She wanted more of a challenge. She knew she could take them down within a few minutes, but she wanted to have something to fight against as a warmup for the fight she planned with Ikari in Japan. She was actually disappointed that it was so easy for her. They once again tried to attack her, but she this time she kicked them away. Her attention snapped over to Mikey, who had managed to avoid her kicks. She walked up to him and grabbed his nunchuks, twisting them and yanking them from his hands. But instead of using them herself, she threw them to the sides. Mikey backed up, but Sarah followed him.

"Sarah, stop it!" Akita insisted from a few yards away from them. Sarah's ears drooped and her shoulders slumped forward. Her eyes began to turn back to yellow. She started walking over to Mikey again, but this time she didn't seem to pose a threat. Everyone else relaxed slightly. Sarah wrapped one arm around Mikey. The other one pulled something small out of her pocket, and she flipped her hand slightly. Then, before anyone could react, she jabbed the object clear through Mikey's shell. It was a pocket knife, that was what she had gone into the kitchen for before. Sarah pulled back and kicked Mikey, who fell backwards. He put his hand to the crack in his shell, and Sarah watched this amusement as blood ran around his fingers. Akita, Leo, and Donny ran to him. But Raph had other ideas. He grabbed his Sai and ran at Sarah, who was distracted by the blood and activity. She snapped back to attention just in time to back away from the flying Sai coming at her. But the blade caught her arm and cut from her elbow to her wrist. Then she tripped over her own feet and fell backwards. As soon as she hit the ground, her colors returned to normal. She laid there for a minute to regain the breath that had been knocked out of her. She slowly got to her feet and put her hand on the cut that was bleeding. She looked at it for a long time, then looked up cautiously. Her eyes had turned back to the topaz yellow they were suppose to be. But then they opened wide when she saw the commotion a few yards from her. She took a hesitant step forward and winced, then started to shake.

"What....no..." she whispered, then spun on her heel and ran into the forest as fast as she could. Even when she couldn't breath, she kept running. Finally, when she was deep in the woods, she fell to her knees. There she let the tears she had held in fall freely. She made the mistake of tightening her fists.

"Ow!" she let go of the bloody knife she had been holding. The knife was covered in not only Mikey's blood, but her own. How could she live knowing she had tried to kill her friends? Carefully, she picked the knife back up...

O_O What!? What the hell did I just do!? Did I just try to kill Mikey!? Yes, yes I did. And it all goes along with the story! Actually it's just something I really wanted to put in there, it wasn't necessary for me to put it there. So, tell me what you think, and what you think will happen in the next chapter. But it might be really obvious to those who think of that kind of this. And those who actually read the next to last sentence! XD Right, so please review!
