Author's Note: What? Two chapters in one day? Well I was working on this one while finishing up Isabella's chapter and it would have been very rude of me to just not show it to you.

To bajy, Isabella is to experience more than the others have, especially in the future fanfics I have planned for her.

Anyways, I don't have much to say, except enjoy.


I'll never forget that day. I mean, who would? After thirteen years of never actually knowing what happened in the lab, I've seen a monstrosity that came from there and what's my first reaction? I... I slain him. It was more of a mercy kill since he was just in so much pain, but still... I just murdered someone. I guess it comes with the job of a kunoichi.

I sighed as Donnie parked the truck in the alley just next to April's new antique shop and we all jumped out. Casey had just parked right next to us with his motorcycle. She asked if we could help out and of course we said yes. Anything to help a friend. Plus, there was nothing to do back in the lair besides Master Splinter's two hour training session. Mikey rang on the door bell with a big grin and April immediately answered.

"Hi, April. Green brothers movers and schleppers reporting for duty." Mikey announced. "Hey guys, thanks for coming. I need all the help I can get." April smiled. "Mikey, you can start by moving those big heavy boxes." Mikey looked back at me and smirked, before walking in. "Just let me put on my hernia trust." He joked. "Right over there, wise guy." April pointed, "Plus I got a heater that won't heat."

"Hence, these." Don commented, showing her the pipes while hoisting a bag of tools over his shoulder before continuing into the building. I walked in right after Donnie. "Bella, could you help sweep the floors? All this dust needs to go." April instructed. "Not a problem," I replied, walking in and looking for the broom. Leo and Raph followed. "You two, that whole wall of antiques needs moving. Carefully." I winced at that. What? Could anyone blame me for doing that? Especially while she's talking to the hotheaded turtle of all people?

"Hey, I'm a ninja not a-" Raph got interrupted by Leo. "Your wish is our command," Leo said as he pushed Raph inside. I heard footsteps walking in and turned to see April looking at Casey. "You're... not a turtle." 'Wow, April. Great first impression on the guy,' I thought, having found the broom by then. "Uh.. definitely not." Casey replied. "Hope you don't mind. We brought along a friend." Leo explained. I smirked and mumbled, "Oh she doesn't mind at all.~"

April extended a hand out to shake his, instead he just waved. "Yo, uh.. Casey. Casey Jones." He introduced himself. "Hey, nice junk." He started. "It was my dad's." She replied before correcting herself, "The shop, I mean. I'm reopening it," She stammered and tossed the feather duster away, "for now until I can figure out what to do with myself. My last job ended kind of.. weirdly." I look between the two as I kept sweeping. "Oh, I get it. While you're waiting for a real job to come along, you're just hiding out in your pop's junk shop. It's cool." I winced as Casey said that. 'Oh, not a good start.'

"It's an antique shop," April pointed out, "and I'm not hiding from anything." Casey just smirked with, "Hey, whatever babe." April huffed, "Babe?" She shook her head at him as the long haired man turned back and decided to lend Raph a hand. "Hey Raph, that's a two man job." Casey stated, going to Raphael who was handling the shelf with the antique china. I did a double take at them before getting away. "Oh this is not going to end very well," I said as I jump behind the counter, hiding from what's going to happen.

"Guys, guys," April began, "Careful. That's very rare-" She got interrupted by the sound of the dishes breaking, "antique china." I looked up to see the predicament that just happened and sighed. "Hey, relax. We'll clean it up," Casey offered. April just groaned annoyingly at them. "Geez. Is your friend always so sensitive?" He asked to Raph. I only shook my head and sighed once more, before sweeping up the dust and the antique china mess. 'They're just two bulls in a china shop.' I thought to myself.

It wasn't long before we finished cleaning up the shop. It looked so much better than it did before, except for a few missing antique china pieces due to two certain hotheaded people. Like I said, they're like two bulls in a china shop.. Well, in an antique shop to be more specific.

We were called in the next night for some protection duty for April. "I'm a little nervous about these robberies," I hear the red-haired woman say. "The jewelry store that was robbed is right on my block. So that's why I asked you for a sleepover tonight." Raph was the first to get up. "Don't worry, April. We got ya covered." He said as he headed to the window to signal Casey outside. "I feel so much better having you guys here."

Mikey just had a smug grin. "Hey guys, who's up for a movie marathon?" He asked, not waiting for an answer as he put a tape in. April shook her head with a smile and went to get the popcorn. I went along with her to get the other snacks.

"I have to ask, Bella. How do you manage to live with four guys your entire life? Isn't it kinda hard?" April inquired. I sighed, "It can be sometimes, but as hard as it looks, most of the time it's quite exciting. They kinda helped me a lot in a plenty of ways and I'm rather thankful for that." I said with a smile. April's green eyes had softened and she had her hand on the back of her head. "Well, it's good that you're so close to them."

"Just remember that big sister is here for you too." She wrapped an arm around my shoulders and smiled. I smiled back, "Thanks. Now let's get these snacks out to Mikey. He gets cranky without them." I look to see him with a mocked glare, "I do not.~"

"You do too, Mike and you know it's true," I replied back to him. "And I'm picking the next movie." He huffed mockingly and grabbed the popcorn bowl from me. "Fine."

Hours passed and I was watching the fight between the two Kaiju. April had gone to her room and the guys fell asleep one by one. 'Some bodyguards they turned out to be.' I thought. I began thinking about the Mutant that I had-.. 'I remember I ended up going back the next day to see it and I actually noticed more details than before. He had whip marks like someone was playing ringmaster and he had enough of that person. Then there was the missing fin. It was torn off like it came out of a cage and the frilled hood got caught on the bars. I noticed that there was a clean slice across the beast's neck. That's why he couldn't say anything. Someone made him mute. He was only able to make noise and yet he was able to speak. Granted it was broken speech, but he still spoke.' Suddenly, I heard something downstairs, breaking my train of thoughts.

"Guys.. Guys, wake up." I tried shaking one of them. I almost forgot that they were heavy sleepers. Honestly, you'd think after living with these guys I would know that, especially how I used a marker on Mikey. Well, there's a few things I can do. Waking up Mikey would be easy, and he's known to be loud so he'll end up waking everyone else. I got up and grabbed a rolling pin from a kitchen drawer. I was just about to whack him with it before I heard yelling from downstairs. Leo jumped a little at the noise. "Guys." He reached to Mikey and shook him on his shoulder, only to get "can I have another s'more?"

I shook my head and sighed. Leo tapped him on the shell. "What?" Mikey asked, sitting up. "Shh, noise downstairs." Leo pointed. Everyone else got up and we left just before hearing April's door open. We left out the window and one by one we landed in front of the machine with Mikey first and me last.

"Okay. What is that? Donnie?" Leo asked, looking to Don. I looked to the giant robot with the masks. It looked a little cute, I guess? "Uh, insufficient data, boss." Donnie said in uncertainty. The man started to freak out over the sight of us and ran behind the giant robot. "Ah. This can't be happening." He hid behind the machine. "Martians. Just when things are finally going my way, we get invaded." The robotic hand curled to a fist. "Don't let 'me get me, kid."

'Kid? This gigantic robot is really a kid?' I thought just before this said kid slammed his fists down, making us fly back. Raph recovered first and flipped back to the robot, slashing it with his sais to no avail. Mikey went next, leaping from his spot and kicking it in the back, only to be backhanded by the robot. He landed next to Donnie, asking the turtle. "Shouldn't you be having an idea right about now?" Donnie only pulled out a blowtorch. "Hold that thought. Just keep him busy."

"I knew you were going to say that," Mikey replied. "Then why'd you bother asking?" I inquired, swinging my kusari around before wrapping it around an arm. I should have done otherwise. The robot just grabbed me, picking me up and looking at me. The masks changed to a questioning expression. It dragged out a letter as if it was trying to learn a new word. "Little sis!" I hear Raph yell. "Sis?" The robot spoke before turning its mask to the one which was grinning. "Put my sis down!" Raphael growled, gladly stabbing the hand it held me in. It yelped and dropped the both of us.

The robot's expression changed back to anger. It looked between the four of us before striking down on Leo. Luckily the turtle dodged in time, sliding between it's legs to avoid the hit. We followed Leo and the robot turned to us, allowing Donnie to get close and use the blowtorch on its back. Its mask turned to a pained expression and it screamed out with a child-like voice before hitting Donnie, making him fly and hit his shell on the brick wall.

"Donnie! You alright?" I ran to him, asking the turtle. "Y-yeah. I'm fine." He said, flustered. 'Why the shell do they get flustered like that?' I thought to myself. "Don't let them aliens get you kid!" I hear the man yell, "Knock them flat." Leonardo approached the man, putting a katana back in its sheath and pointing behind him. "What do you know about this?" The eldest brother interrogated him. Raph and Mikey approached him as well, causing the man to freak out. "Help, kid." I watched from the side as the expression changed to a worried one. "Daddy." It spoke and threw my brothers aside, grabbing the man and running away.

April came out just in time. "What was that thing?" She asked. No one answered. Instead, Casey groaned in pain. The others and I looked back, seeing him struggle to get up. "Casey! Oh no!" April yelled, running up to the long haired man and grabbing him by the arm. She removed his mask and placed a hand on his forehead. "So.. uh.. did I win?" He asked, looking at her. I rolled my eyes at that.

"Hey guys." We looked back to Donnie who held some weird thing. "This stuff is moving!" It looked like a piece of metal that fell off of the robot and it moved around like tentacles, only it didn't grab on to anything. "I better get this analyzed." He said. I nodded at that before we all headed back inside. April and Raph helping Casey to the sofa. I helped April by grabbing the first aid kit for Casey. He was banged up pretty badly. It's no wonder April was worried about him. Donnie was busy examining the piece of metal before he spoke with astonishment, "Woah. Definitely something you don't see everyday."

"What did you find?" Mikey asked. "Take a look." Don said, moving away from the microscope. Mikey approached the microscope and looked into it. "Eww, what are they?" He pulled away and I decided to take a turn to look into it. "They kinda look robotic parasites." I replied before Donnie spoke as I turned the wheel on the side, "Actually they're nano bots. Microscopic robots all working together."

"Are they dangerous?" Raph asked him. "They're moving randomly. Probably when they were cut off from the main group, they became mindless, unmotivated." I pulled away from the microscope right when I hear Mikey go, "Oh like when Raph goes solo. He becomes mindless, unmotivated." He pointed at Raph. The hotheaded brother only slapped his hand away. "Speaking of mindless," he began, "did that thing seemed kinda... lost to you?"

"Yeah like a little kid." Mikey replied, using his hand to emphasize on a child's height. I nodded a little before hearing Don say, "Uh oh. It's reproducing itself and if each nano bot makes a copy of itself and the copies make copies, this thing could really become unstoppable." Leo slapped his fist into his palm and said, "Then we stop it now. Is there any way to trace this thing?" He asked. Don hummed in thought with a finger on his chin. "Hmm, the nano bots have a unique power signature." He snapped his fingers. "Hey I bet the tracker in the Battle Shell could get a lock on it."

"And once we find robo-boy, then what?" Mikey asked. Donatello just grabbed the blowtorch and responded with, "As much as it pains me to destroy such amazing technology," He placed the flame of the blowtorch near them. "It does seem to be susceptible to extreme heat." I could see bits of smoke, meaning that these little robots were burnt away. "So, what're we waiting for?" Raph asked and we left out the door. Raphael went back to ask Casey something. I don't know what, but it looks like it didn't take long since Raph came out a moment after.

It took a little bit of driving and following the signal before Donnie had said something. "We're almost on top of it." He looked to the screen, watching the blip blink. "Should be right through there." He made a sharp turn and I ended up on the floor again. "Don! How many times do I have to tell you no casualties?" I yelled to him. "Sorry Bella." He apologized. "Need help getting up, sis?" Raph asked. I managed to get up and get into a seat. "Nope. I'm fine."

I looked to see that we were in the junkyard. 'Huh, it's actually quite genius. No one would think all this was just stolen items at first.' I thought, 'Not that I'm impressed or anything.' I hear the door open and we all went out, jumping on a pile of stolen items. "Look at all this stolen stuff." Leo remarked. Donnie looked around before looking down at his device. "Where is that thing? The locator says it should be right here."

Mikey spoke in uncertainty. "I know it's been used before guys, but I'm getting a ba-a-a-ad feeling about this." He bleated much like a sheep or a goat would. "You're telling me," I replied. I didn't like this bad feeling either. Suddenly we heard something mechanical behind us before seeing the gigantic robot jump up out of hiding and tried to stomp down on us. Luckily we jumped away and took our stances, readying ourselves as it stepped towards us.

It's expression went to anger and cords flew with visible nano bots taking apart items and reassembling them into limbs, causing the robot to grow in size. Its masks were now played on the screen, still showing the face of anger. "And now, I'm getting an even badder feeling about this." Mikey spoke. Before I could even sarcastically respond to him, the robot screamed out. "Uh guys? Anybody wanna tell me how we're going to do this?" The jokester asked.

"Like we always do. Together. Hit it so fast, it can't rebuild itself." Leo instructed. With that, we yelled out and leaped into battle. I jumped up, wrapping the kusari around a digit and pulling myself down, slashing it off with the Kama part of the kusarigama. Just as the large finger dropped, the robot yelled in pain, looking at it before using the parasitic like robots to reattach the finger to its hand. Apparently, I distracted it for Leo to slice off the other hand. The robot screamed even louder and the nano bots moved around, almost like the blood you see in gore movies. Yeah, I got sick during those movies. Mikey learned the hard way not to show me gore movies ever again. It looked to its hand before doing the same thing, repairing it and reattaching it to his wrist.

The robot glared down at us before lunging its hand down, grabbing Mikey. "Mikey!" Leo and I yelled. The turtle in blue tried to slash at the hand again, only to miss and slice the air. The hand lifted Mikey up before holding onto his leg, swinging him around a little. "Woah! Not good!" He yelled out before being swung around. "Whoa!"

"I'm coming, Mikey." Donatello yelled. Admittedly I had wanted to say something, but now wasn't the time. The yellowish-olive turtle ran with a blow torch in hand. "Make it quick. I'm gonna hurl. Literally!" Mikey did look a little greener than he was supposed to be. The turtle with the purple bandanna jumped to the top of the pile, about to turn on the torch before he got hit, landing on the ground and sliding on his shell. "It's fast!" He exclaimed with Raphael now at his side. "That's not a good thing, Don!" The oddball in orange shouted before the giant robot decided to let go of him, causing him to fly, crash and roll off the pile of trash.

"So, I'm going to say that plan didn't go so well." Mike commented, standing up on his feet. The robot towered over all of us and he raised his hand, curling it into a fist. "Plan B?" Don suggested before Leo confirmed, "Plan B." With that in mind, I turned and ran with my brothers, going into the Battle Shell. Michel was now the one driving. The vehicle sped off with the giant robot following us.

It suddenly stopped. Mikey was still putting the pedal to the metal, so that would mean that the robot just grabbed the Battle Shell like the toy car we had when we were just kids. Of course, Don accidentally broke it when he was tinkering it. I suddenly jolted from where I was and landed on my back next to Don and Raph. They are so lucky to have shells. I thought as I yelped out. Just as I got up with the others, I saw a circular piece on the ceiling get lifted. The robot is taking us apart!

"Faster Mikey! It's taking us apart!" The brainiac commanded, turning his head to him. "I'm giving her all she's got captain! She cannot take them harrrrrd." He rolled his tongue, emphasizing on the r. Leo turned to Raph and I. "Raph, you're on. Shell Cycle time." The hothead had already picked up his helmet. "Sure, I always have to do the crazy stuff. C'mon, lil' sis." He spoke to me. I couldn't hesitate now, so right after he got on the red motorcycle. I went behind him, holding onto his shoulders. "I don't like this idea." I mumbled.

"Keep him busy until we're in position!" Leo yelled over the cycle's noises. Raphael revved up the motorcycle before speeding out the back door. The robot now stared at us as Raph made the bike circle around it. It yelled angrily, trying to slam its hand down at us. I just held onto the hotheaded turtle while he drove as fast as he could. I just looked back at the giant robot. To think that this thing.. is really just a kid. It was almost like the same situation back in the Underground Lab, but of course this was a robot, not a mutant.

I looked ahead to see the trash compactor. Oh now I see what they're doing. Raph drove just in front of it as the robot got closer. Just in the distance, the Battle Shell sped towards us and Raph drove around it, getting out of the way. "No! Look out kid!" The man yelled to him, pointing to the Battle Shell. The robot looked behind him before getting rammed on his legs and falling over into the compactor. It screamed as it got crushed like a can of soda. "Yeouch. Looks like dat did it." Raph commented.

Mikey snickered. "He-he yeah. He's flat broke." I rolled my eyes at his obvious pun and Raph just groaned annoyingly. "You know, I'm gonna stop with the puns." He said unexpectedly. "Really?" I said, somewhat hopeful that he actually would. "Seriously. They always come back to bite you." I looked to see an all too familiar giant hand with nano bots reshaping it back to the way it was. Raph started up the motorcycle again before riding away from him. I wrapped my arms around him, my hands being on the upper part of his plastron. I could feel him smirking at the action. "Kinda clingy, aren't ya, sis?" He smirked at me. I huffed, "Now isn't the time, big bro."

"Leo tell me you gotta Plan C. I'm really hoping you gotta Plan C." Raph told Leo. "Plan C at twelve o'clock." He replied over the communicator. The robot was just right on our tail. It lifted its fist high above its head. "Uh fellas. Plan C. Now." Just as it was about to slam down and flatten us, the AI was just lifted by a giant magnet. The expression changed from anger to scared. "No! Kid, are you alright?" The man yelled. The robot just screamed out in fright as the magnet turned. I just kept watching. What do I do in this? My brothers want to make sure the robot doesn't cause any harm to anyone, but this thing is just a child and it got the wrong parent. It was a bad time to be indecisive.

I have two choices. One, I could go against my brothers wishes and try to save him or two, I could stand to the side and allow this to happen, but that would mean ending a innocent life, even though it was dangerous. I panted before letting go of Raph. "Sis, what're ya doing?" He asked. I didn't answer. Instead, I jumped off the bike and barrel rolled, wincing as I hit the ground. I looked and saw Raph turn his bike around, stopping for a moment to stare at me. I looked to around, seeing Don operate the magnet in the control center. I have little time. I thought before getting up and running to the machine. "Sis!" Raph yelled from afar.

The sound of the motorcycle was becoming distant as I got closer. The robot struggled on the magnet, trying to pull itself off, unaware of being on top of the incinerator. 'No. Don't move.' I panted heavily. The human man must've been unaware of where the magnet was positioned because I heard him yell, "Hang on, kid. Daddy's coming!" He went for the switch on the side of the machine.

"No! NO! WAIT!" I yelled, hoping he'd figure out what was about to happen.. but he didn't listen and pulled the lever. The control center Don was in turned off and the magnet had lost power, letting go of the robot. The child-like scream echoed possibly throughout the city. The robot had looked to me for a moment and I could see its scared expression turning into one of terror as the robot fell into the now open incinerator.

"No! No!" The man yelled, heading towards the incinerator. A hand raised up from the heat and the giant gently glitches out a "Daddy" to the man. It fell back down into the fire as the doors now closed, engulfing the flames with it. The criminal went to his knees, grabbing the mask that the robot once had on and his shoulders shook. I could hear him sobbing. 'He cared for him and he didn't even know it until now.' I thought sadly. "Bella, Don, come on. We gotta go." Mikey said from his front seat. I didn't have much of a choice now. I followed after my brothers, hearing sirens in the distance. Right before the police came, we left.

Donnie had took back his spot in driving. Mikey switched to the back seat with Raph. My hands went to my face and my elbows met with my knees. It was silent for a while before Mikey broke it, "You know. I feel kinda bad for the little bot." 'You should feel bad.' I wanted to reply, but refrained from doing so. "Lil'?" Big bro questioned. "You know, he was kinda like a little kid." Mikey replied. "Too bad he had such a rotten parent." Don commented. "Yeah, I bet he would've been better with us, right Bella?" I could feel Mikey smile. I didn't bother to respond. "Bella?" "Lil' sis?"

I just sighed and thought, 'He was just a child, an innocent little AI child. He was just doing what he was told and my brothers just... they just..' I didn't respond as we parked next to April's. I followed the two out, my hands sliding off my face. What? I couldn't look like I was moping over our enemy. "I'm just glad the fighting's over." Leo said as we approached the door. He opened it leading us right into the middle of an argument between April and Casey.

"Take care of me? I only got hurt because I was saving you." The long haired man sneered. "Oh, so you think I need saving, is that it?" April argued back. "You twist around everything I say. Ah, women." He spat back."Why of all the myopic, misogynistic-" "Geez. How'd you even talk if you won't speak English?" Casey asked as he just accidentally knocked a vase over, causing it to break on the floor. "I told you to watch the antiques, you big ape." They just kept yelling at each other. Leo just pointed. I guess he was going to say something, but decided against it.

"I think they want to be alone," Mikey said. I nodded at that, still thinking about what happened earlier and what could've happen if we did something different. 'What would've happened if we had spared him?'


Author's Note: I guess you're wondering why Isabella feels the way she feels, huh? Well, she feels guilty, but she's trying not to let it show. Something she picked up from Splinter and Leo.

You see, Isabella is not like the turtles or anyone else. She was once a merciful little child. So kind.. and a little too pure to be a kunoichi, but it literally took one time of being merciful to nearly get herself killed.

If I told you, what happened specifically, then I'd be spoiling you guys with a future one shot. I guess if you want to know, you'll have to wait until then.
