Chapter 19: Sacrifice.

"Where are we going?" Kaliyah asked as the group followed the genius turtle through the cemetery.

"The exact coordinates." He responded distractedly, glancing down occasionally to the gadget in his hand.

"Are we almost there?" Mikey asked. Donatello flashed him a look of annoyance and the younger turtle shut up.

"Here!" Don shouted after a few more minutes of walking. They were facing a huge tomb, one that looked as if it housed an entire generation.

"Think it's in here?" Mikey asked.

"Probably," said Kallie. "Ready to use your lock picking skills?"

Mikey grinned. "Always."

Mike unlocked the door with ease and the five of them stepped into the tomb. There had to be at least twenty name plates lining the walls where the dead family was buried. Kallie couldn't help but shiver. Not only was it cold, but it was eerie too. Kaliyah never did well around death. They five of them split up and looked around the tomb, trying to find what the key could possibly belong to.

"Hey, I think I found it." Don called.

Kallie all but ran to him and saw that there was a little wooden chest sitting on a stone shelf. Kaliyah took out the key and slipped it in, and the key did indeed fit. Kallie's heart was pounding once more as she turned the key and unlocked the chest. The young woman wrenched the top open and looked inside.

Nestled in a small cushion was a vial full of a bright blue liquid, it seemed to practically glow. Kallie picked it up and gasped at the warmth that radiated off of the vial.

"Are you okay?" Leo asked, grasping her arm.

Kallie nodded. "Y-Yeah...it's just...it's warm."

"What?" Don asked, making his way to Kallie and holding his hand out. She handed him the vial and Donnie started examining it.

After a few moments he finally spoke. "I've never seen anything like this before."

"What is it Donnie?" Mike asked.

"I have no idea," said Donatello. "We need to get this back to the lair. I'll be able to examine it further in my lab."

"Is it dangerous?" Kallie asked.

"I honestly have no idea, I'm sorry Kallie." The genius turtle replied, a sad look on his face. Kallie guessed that Don didn't exactly like the unknown.

"Don't apologize Donnie, it's fine." She told him gently with a smile. "We'll figure this out together right?"

Don smiled back at her. "Right."

"Well let's get going then," said Leo. "The faster we get back to the lair the better I'll feel."

"Worry wart." Kaliyah muttered. The leader shot her a look while Raph and Mikey snickered. Kallie grinned at him and he rolled his eyes, but not before a wry smile graced his face. Kallie let Donnie hold onto the vial as the group made their way out of the tomb. Once outside, Kallie looked up and saw that there was a surname carved into the stone of the tomb: Collins.

"Huh." Kallie said aloud without really meaning to.

"What is it?" Leonardo asked.

"That name is my mom's last name." Kallie responded.

"Her maiden name?" Don asked.

Kallie shook her head. "Her new married name. It's Robert's last name."

"Very good Kaliyah, I was beginning to think that you'd never connect the dots." A voice said. Weapons were drawn as the human and four turtles turned around to face the newcomer.

It was Robert.

"Robert?" Kallie gasped.

The man stepped forward, a calm smile on his face. He was wearing his cop uniform, his badge shining in the moonlight.

"Hello Kaliyah." He replied.

Kallie's expression turned dark, her anger at seeing him rising as her suspicion grew as well. "What're you doing here?" She demanded.

"Would you believe that I was simply worried about you?" He asked, that calm smile still on his face. It unnerved Kallie. "I mean, my daughter is out running about with four mutated turtles."

"I am not your daughter." Kallie snarled back at him.

"You're my step-daughter."

"No I'm not. I'm nothing to you." She insisted.

"Oh but Kaliyah…you truly are everything." He replied.

"One step closer and I will end ya." Raphael hissed as Robert came closer. Robert turned his attention to the red banded turtle and smiled.

"Calm down Raphael, I have no wish to harm her."

"How the hell do ya know who I am?" Raph demanded.

"I know everything about all four of you," said Robert, and then he turned to look at each turtle one at a time as he spoke. "Leonardo; the oldest, the leader, and the most well trained. Raphael; the second oldest, the brawn of the group, and the most hot tempered. Donatello; the third oldest, the brains, and the most peaceful. And last but certainly not least is Michelangelo; the baby of the little family, the heart and soul of the group yes? Karai couldn't even break you. You are so much stronger than anyone gives you credit for Michelangelo."

"Don't talk to him." Kallie demanded, standing in front of the orange banded turtle. The three others had moved in closer as well. "In fact, why don't you just get the hell out of here?"

"I'm not leaving here without what I came for." He told her.

"Back off Robert, this has nothing to do with you. Retreat now and we will not harm you." Leonardo said in a chilling voice. Robert laughed, a cold and harsh laugh.

"You are truly a frightening creature Leonardo," said Robert. "However, you do not frighten me. And on the contrary, this has everything to do with me."

"What do you mean?" Kallie asked.

"Oh Kaliyah…for someone so smart you sure are so unaware of what is going on right in front of you." Robert replied with a shake of his head.

"Enough games! Tell me what it is that you're after!" Kallie shouted.

Robert whistled and made some kind of motion with his hands. The boys tightened their grips on their weapons and got into a more defensive stance. All of a sudden figures started emerging from the shadows all around the cemetery, making their way towards Robert. Raph growled low in his throat.

Foot ninjas.

"So you're working with them…" Kallie murmured, overwhelmed by the sheer number of ninjas in front of her. There had to be at least a hundred, no expanse of the cemetery was empty of a ninja clad body.

"You have no idea how long it took me to orchestrate this whole thing," said Robert, that same calm smile on his face. "It took a while, years actually."

"Orchestrate what?" Kallie asked, her voice low.

"This." He gestured wide, twisting left and right. "It all began when he found it and tried to hide it."

"He?"

Robert looked at her, a malicious glint in his eyes. "Your father."

Kallie gasped, feeling the breath leave her body all in one go. She reached behind her, trying to steady herself, when she felt a hand grasp hers tightly. Without even turning around she knew it was Michelangelo. He gave her hand a squeeze and she grasped it tightly back.

"What do you know about my father?"

"Much more than you know that's for sure."

"Shut up." Kallie whispered, feeling her throat close tight. She refused to allow Robert to lie to her. She knew her father. She knew her father better than anyone else in this world...right?

"Secrets are what your dad was good at."

"Shut up." Kaliyah repeated.

"You still have no idea what that thing does do you?" He asked, motioning to the glowing vial in Don's belt. "You've been sent on this wild quest and you still have no idea what it is that you hold. It's a secret right? A secret that he didn't reveal to you. And he won't you know, this is the last clue, the rest is up to you to figure out."

"Shut. Up."

"It really is quite the puzzle. I'm still trying to figure it out myself. I'm very close though, all I'm missing is one piece."

"And what piece is that?" Leo demanded.

"Kaliyah." He answered simply.

"You're not going to lay a finger on her." Leo growled.

Mikey pulled on Kaliyah's arm, tugging her back towards him but she shook him off and ran back to the front of the group.

"Kallie!"

"Get out of here. Now." Kallie warned Robert.

"I'm not leaving without what I came here for." He repeated. Kallie glared at him as he smiled broadly and held up two fingers. "Bring her to me."

And the fight was on.

Leonardo shoved Kallie behind a headstone as he threw himself into the fray. "Raph! Protection duty! Don, Mike, c'mon!" Don threw the vial to Kallie as he followed his brothers into the fight.

Raph started plowed through three Foot who had managed to get past his brothers, shielding Kallie from them. Kallie could only look in absolute horror as the four turtles valiantly fought through the horde of ninjas.

"Raph!" Kaliyah shouted as a ninja came from behind. Raph easily kicked him from behind without even looking. Kallie could hear grunts as fists and weapons connected with bodies. Kallie did her best to alert Raphael whenever danger was approaching, but there was only so much she could do. Raph was constantly moving around her, pushing her behind him or shoving her to the side to avoid a flying shuriken. Kaliyah let him do whatever it was he needed to in order to keep him safe. She couldn't do much of anything anyways. She didn't have a weapon of any sort and she wasn't sure if she was on par with any of the ninja out there fighting.

Suddenly she didn't have a choice.

Raphael was taking on four at once as a Foot soldier grabbed her from behind. Kallie felt the guy wrap his arms around her waist and try to hoist her up. Kallie elbowed him as hard as she could in the gut. The Foot soldier grunted and his grip loosened enough for Kallie to slip out and land a solid punch to his jaw. It hurt so much worse than she had imagined it would. Her knuckles felt as if they were on fire and she gasped as she shook her hand, trying to help alleviate the pain.

"Nice goin' Blondie!" Raph yelled out to her. Kallie turned to smile back at him when another ninja came at her.

"Duck!" Raphael commanded. Kallie heeded his warning, dropping to her knees immediately as a Foot came sailing though the air. The red banded turtle caught the guys' ankle in mid-air and threw him across the cemetery. Kallie saw another ninja pop up behind Raphael and she quickly kicked him in the back of his knees, forcing him to fall. She took advantage of that and grabbed a large branch she saw on the ground, slamming it down on the back of the ninja's head, effectively knocking him out.

"Ya knocked him out?" Raph asked, jamming a Sai into a ninja's gut.

"Yup!" She called back.

"Sweet!"

"I learned from the best." Kallie didn't know whether it was the adrenaline pumping through her veins or the complete concentration that had her moving so fast and strong, but she felt as if she was truly helping. Every so often a Foot soldier would slip by and make a grab for her and Kallie used every lesson she was ever taught by the boys to help keep them away from her and Raphael.

Raph was like a bull. He was plowing through Foot after Foot after Foot. The only time someone go past him was when he was taking on three or four at a time and luckily Kallie was able to incapacitate each one. It was easy to see that the Foot thought she was weak. She was no ninja of course, but over the course of the months she'd been at the lair the guys had taught her a lot of really great things. She regularly participated in sparring matches now and she even worked with weapons. She hadn't gotten the chance to get her own sword yet though and now she was really wishing that she had. It would've made this whole fight a lot easier.

"Raph status!" Leo's voice called from the distance.

"Doin' just fine!" The red banded turtle shouted back.

"Kallie?"

"A-Okay!"

"Mikey?"

"I'm good dude!"

"Enough!" A voice suddenly bellowed. The Foot immediately retreated, running to the middle of the cemetery where the voice called out. And in the middle stood Robert.

With a knife to Donatello's throat.

"Let him go." Raph snarled.

"You aren't in any position to be making demands, unless you want to see your brother's blood spilled all over this cemetery." Robert replied menacingly, pressing the knife and drawing blood.

"Stop!" Leo shouted, taking a step towards his little brother.

"One more move and we'll see just how human this mutant is."

Leo tightened his grip on his Katana's and stepped back.

"Let him go." Kallie said softly, slowly making her way to where Robert was holding Don.

"Kallie—"

"It's over Raph," said Kallie, interrupting him. "Let him go Robert, I'll come with you."

"Kallie, no." Don croaked out.

"Kallie you don't have to do this." Leo told her as she walked past him.

Kaliyah smiled at him. "I don't have a choice." She finally reached the vile man she had hated with all of her heart and soul. Don was staring at her with wide eyes, his fear shining through. "It's okay Donnie." She told him.

"Kallie…" He managed.

"Alright, I'm here now. Let them go." She told Robert.

Robert smiled coldly at her and quickly shoved Donatello away from him as he grabbed her and immediately had her in the same position Don had been in, the same knife pressed tightly against her own throat.

"Don't think about playing the hero's. One move and her throat will be slit." Robert told Don as he immediately reached for his Bo, his hand stopping when he mentioned killing the young blonde.

"You need her." Don growled.

"She is most beneficial yes," said Robert. "But we could figure it out eventually. She'll just save his a lot of time and a lot of money."

"Then why go through all this trouble? Take the vial and leave her!" Leo shouted.

"Because I'd rather save the time and money." Robert replied simply.

"This ain't over!" Raphael shouted.

"You will pay." Mikey said dangerously.

"I'm sure." Robert said, a bored tone to his voice. He smiled sharply suddenly and then snapped his fingers again.

"Kill them."

"NO!" Kallie screamed and soon she was fighting with all she had against his hold before she felt a sickening pain in the back of her head and her world went black.
