Author's Note: Sorry to have kept you waiting. There was a whole lot of procrastinating and editing. I was especially hesitant to publish this since this chapter is Isabella's chapter. Basically, it's her own episode and it begins her small arc.

Now if I told you what her Arc was about, then that would be spoiling you guys.

Before I accidentally say something about it, how about you actually read and find out yourselves?

Those flames... I couldn't stop thinking about them. It's been weeks since my brothers and I had defeated Stockman. Not much has really happened, except for training. Tonight, I will be meditating after training, though I feel that this won't be the only thing I'll be doing.

I had just recently finished training. Don went to help April with something, Mikey went to the television, Raph was busy beating the living shell out of his sand bag and Leo was with Splinter. I left to my room to meditate. I took a seat on the little rug and tried to relax my mind. I couldn't. After everything that's happened, with the Mousers, Baxter Stockman, and the destruction of his lab. I couldn't help but keep remembering about it... The fire and the wrath it held. How it just ate up everything without any thought.

I eventually gave up and sighed sleepily. Don't blame me for being sleepy. Like I said, so much happened within the span of time and plus, training was exhausting. I know I should be used to it, but change can be tiring as well. I kept my seat though while I felt myself relax and drift off. My eyes fluttered shut and I could only see darkness.

'Nothingness.. Silence... They filled the void so easily. It was dark. To Isabella, darkness wasn't frightening. She learned to live with it; to live in it. She had to, due to what she was. The world wouldn't accept what she was so easily. Her family and her knew that little fact. So the darkness was actually comforting for her, but the comfort didn't last for long. It became... kind of scary, to be honest. Isabella shouldn't be scared of the dark though. She had no reason to, but she should have a reason to be.

A pair of eyes opened up slowly, tiredly almost. The lightest shade of blue being glossed over with age. A shape took form and it approached Isabella. It looked familiar to her, so she shouldn't be scared of it. It looked like her Master Splinter, but with round pink ears, ivory fur, different shaped eyes, and a pink tail. Isabella doesn't really remember someone with this look, but.. deep in her mind, it feels like she's seen this person before.

The rodent opened their mouth and spoke in an aged womanly voice, "Little bell..." On instinct and not even knowing why, Isabella answered back with "Mother?" Before anything else could happen, the rodent disappeared and the darkness shattered beneath Bella like glass, falling down. "Mother!" She reached, hoping that ivory-furred rodent would reappear and help her.. but nobody came.'

"Mother!" I screamed out loudly, scaring the turtle next to me. "Whoa!" Mikey jumped only to fall backwards. My eyes flickered around to see my elder brothers looking back to me and my rat father with his eyes closed in thought. "What was that, sis?" "Yeah, you okay, Bella?" They bombarded me with their questions. Honestly, if I could back up, I would, but unfortunately I'm stuck on the floor. "Enough!" Splinter said over them, tapping his walking stick down hard enough for them to hear.

The four obeyed without question. Leo decided to help me stand and I could see Raph glaring at him for some reason. "Isabella, come with me." Splinter spoke and began walking out. I followed after him, but not without seeing the hothead and the leader glare at each other. I would wonder why they're like that, but there could be many reasons, so I try not to think about it.

I turn my head to look at Splinter, still following after him before going to his door. "Come on in, my daughter." He said. I gave a slight nod and follow him in. "Kneel." I obeyed and kneeled on the ground as he slid the door closed. "Now, tell me... What did you see?" He inquired as he took a seat before me. I hesitated to answer. "Isabella, you can tell me."

Splinter was waiting and I couldn't stay silent due to his patience thinning down. "I.. I saw someone. I don't know who but I think..." I couldn't figure out how to finish that. "It is someone from your past?" He offered to finish. I nod. "Yeah, I guess so." He raised an eyebrow. "You only guess, but you do not know." I didn't reply. I didn't understand what I meant either, but I know I was on to something. Something in my mind was acting up and I really wanted to get to the bottom of it.

"If there is nothing else, then you may leave." Splinter instructed. I nod and get up, leaving him and shutting the door behind me. I noticed that the guys were nearby, trying to look like they were doing other things. "And it seems that your brothers were eavesdropping again." Splinter said and Mikey gave a small meep in surprise. I rolled my eyes at him and left the large living space, heading to my room.

Their gazes just followed me and I heard one of them approaching. "Hey, Bella, what'd he tell you?" Mikey asked. I just rolled my eyes at him and ignored him. "Come on, you gotta tell me, Bell." He kept on pestering me and I just tried to ignore him, but I ended up snapping my tail at him. He yelped at that and jumped away. I could see Raphael smirking at how Mikey was frightened, even though he, too, was at a distance with the brainiac. They knew to stay away whenever I'm irritated.

While he was at a distance, Leo just stared, silently. Like he was waiting. Like he knew something was going to happen. I looked away from him and used my wall crawling ability to climb up and into my room, closing the curtain behind me. Why is there a curtain? Well considering that I'm the only girl living with these guys, I needed a form of privacy. Plus someone threw out some nice curtains. Sure it's a plain color, but I think it looks nice.

I sighed and sat on my mattress, shifting my tail next to me just to sit comfortably... I sat there. Nothing happened. I shifted in my seat. Nothing still. I ended up snapping my tail a little. Seems I was a little more restless than I usually was. Could anyone blame me? I mean, I just had a vision. That rarely ever happens at all. It just kept bothering me. I got myself up and looked out of my room. 'Would they notice if I left?' I thought. I glanced left and right for a moment, noting that my brothers were busy once more and cautiously began walking.

I had to be mindful of the area around me and that each of us had our senses heightened overtime. One wrong move and they would know something wasn't right. I looked around once more. Mikey's eyes were glued on the television screens, Don was working on something in his lab, Raph was busy honing on his fighting skills with a dummy, and for some reason, I couldn't see Leo around them. I looked ahead to the exit, having to guess that he was waiting there. He did the same thing with Raphael when we all chased that Mouser robot. I wouldn't see why he wouldn't do it again.

I had to think. 'How could I get around him?' I thought before looking to my hands. 'I remember now.' I almost forgot about my natural wall crawling ability. I don't know why I'd forget something that I used often. I climbed up the side of the room, going up the wall. While still above ground, I crawled along the wall before going into the tunnel, trying to stay hidden. Seriously if you even shift some light particles around Leo, he will notice immediately and act accordingly, depending on the situation at hand.

I could see him now. His arms were crossed and he looked around, keeping his senses alert. I breathed silently, hoping he wouldn't notice me pass by. With the little light and how he stood, he actually looked... dangerous, much like how a shinobi is supposed to look.

I must have miscalculated while scaling the wall for I ended up making a small noise. His head turned to my direction and I could feel him glaring. Either I move quietly out of his line of sight or I get down to him and explain. Explaining would take too long though and for all I know he's going to try to keep me here. After all, he was fighting Raph just to keep him home.

I didn't want to make this decision, but I had to do something. I crawled along the ceiling, getting away from his line of sight before getting down. As much as I should've revealed myself to Leo, I really need some time to think to myself. I looked back to the entrance of our home just around the corner before turning and walking ahead, making sure to keep silent for a while.

My mind kept going back on the vision. Like it was trying to recall something from my past. I must have been really distracted because I look up and I noticed that I was in a sort of maze. There were three other tunnels. I looked between them, wondering which way should I go.

Suddenly I heard footsteps run, splashing along in the water. I looked to see a figure run pass. It was too fast for me to catch any details. In a sense of urgency, I followed after the figure. I barely caught a few details of them. It ran very fast and I'm glad that my training paid off very well, but not well enough. The being turned quickly, smacking me with an appendage and knocking me off my feet. I yelped at that, landing on my back. Again, my brothers are lucky to have their own armor. It'd be nice to have something like that, but then I'd have to carry it around so much.

I rolled over just as it was about to stomp down on me. Nope. Not again.* I thought quickly and got up. The water splashed up high just as the beast stomp down. I could've sworn I heard a crack and I'm certain that it didn't just break a bone. It hissed at me, staring at me. For some reason, I couldn't look away from its gaze. It had prominent yellow eyes, having a menacing glow with very little pupil like I just caught it in a bad mood. It hunched over and hissed, standing on its toes. It was trying to intimidate me. To scare me off or back down. I wanted to reach for my weapon, but considering that this thing just knocked me off my feet and it cracked the cement beneath its foot. It'd be foolish of me to attack, especially since I'd be outweighed.

I backed up. I had no choice but to surrender and I didn't like the feeling. I never really had to surrender before, except one time... and that time I nearly got myself killed doing so. So yeah, you can imagine why I don't like surrendering so easily. It came close, still hunching over. I kept stepping back until I ended up tripping over my own tail. At this point, it went on all fours and pounced onto me. I didn't have much time to react. How can I? Especially with how it was now above me. I don't think I can do much.

I can feel the water soak my gray outfit, turning it to a darker color on my back. It breathed its hot breath and flicked its tongue like a snake would. I had my head turned away but it just kept itself on top of me. The claws were on my shoulders, pinning me in place. I heard a growling from its stomach right before it opened its mouth at me. 'Oh no you don't.' I immediately thought and kicked it in its side. "Gah!" I yelped out in pain. Good god. It was like kicking at some cinderblock. And now is not the time to ask how I know what that feels like.

"Get off me!" I managed my arm free and grabbed my kusarigama before hitting its snout with the blunt end. I swore I heard a crack. It just hissed, standing above me and holding its snout. Liquid dripped from that said snout and the beast sneered at me. It backed up into some light and I could finally see some detail. It wore a small tattered gray cloak, making me think it wasn't its own to wear like it was wearing a trophy. It had this chimera like look to it. It mostly had reptilian features, but it had gills on the sides of its neck. A frilled spine went down its back and there were fins in its elbows. I saw that there were scars and a piece of its frilled hood was gone. It was harmed like it went into battle and it took the most damage, but some of them looked like torture marks. There was also a tag on its ear and a barcode tattoo on the side. It must've came from a lab. At least that's what Mikey's monster movies taught me.

The yellow eyes glared at me and it hunched over once more. The quills shook as it hissed like it was threatening to harm me if I were to attack again. I wasn't afraid, but I wasn't going to back down. I mean, it was about to eat me, at least I thought so, or it was going to do worse.. and I highly doubt the guys would let it get away with such a thing. "Lil' sis!" Speak of the devil. I heard Raph yell from afar right before I see him jump in front of me. The beast yelled at my brother and swung a claw. The hotheaded dodged and swung a sai at it.

I see Mikey jumping in and swinging his nunchaku at a leg. It stomped down in Mike's direction, ready to squish him with an oversized foot. "What is that thing?" Donnie asked, having his staff ready. "I don' know, but it's big and it's ugly." Raphael sneered. "Hey Raph, looks like we found your long lost relative." Mikey joked, receiving a glare from the said hothead. The beast looked between us as of thinking before looking to see Leo. With that, it backed up, probably seeing that it was outnumbered before turning away. A tail was about to swing at Raph and stupidly, I pushed him out of the way. "Look out!" I yelled before getting that said tail wrapped around me and getting dragged along.

"Sis/Isabella!" I heard them. They ran toward us but I guess the beast was faster. It wasn't long before I was dragged underwater. It was dark... cold.. I wanted to curl up, but I was refrained from doing so. I squinted, looking to see the beast swimming as fast as it could like he was some sort of jet in water. It turned and twisted in different directions in the murky waters before it finally went to the bottom. The beast placed his feet down before kicking up. Like a jet in water, it jumped out of it. I gasped for air while still being held. The beast took a few paces before letting go, dropping me.

I winced. My brothers are so lucky to have shells and to think Mikey complained about his every now and then. I blinked relentlessly, making my eyes clear up and I saw... the beast walking away. Looking around, I saw that we were in a strange place. The smooth concrete surface looked a whole lot different from the concrete I usually saw in the tunnels. I got up hesitantly, still gazing around. There was a technology that Donnie would love to mess with and fix up. I walked through the place, seeing cages with bars torn off, laboratory tubes with broken glass, and the equipment was destroyed.

There was an outrage here and it was vaguely familiar. The ground looked scorched like.. there was a fire. I gasped as my head began to hurt and I saw flames ahead of me.

Flames lapped everywhere. Glass broke from within while metal bars were torn apart. The mutated beasts ran around, finally fighting back against those who tortured them.

I forced myself forward and looked at the cages, seeing some matted fur caught on the metal door.

One Mutant jumped out of her cage, running pass the fighting and down the halls, looking around. "Little Bell, where are you?" The rodent called out.

I went down the same hall, seeing a door that was busted open from my side.

A little voice cried out for the rodent mutant. The owner of that said voice reached out to the mutant. The white laboratory rat had a muscle-bound bull kick and knock down the door. The metal door was busted wide open and the rodent grabbed the little one before running as far as she can.

I could barely see the dark room inside. I get closer to the darkness foolishly before hearing groans of pain. I looked to see the beast hunched over, holding itself and groaning and growling. Now that I'm finally looking at it from behind. I see a blinking light coming from what looks like a dart. The beast growled and roared out. I finally realized. It's in pain. It wasn't looking to attack anyone. It wanted help. Just as I realized that, it turned to me with even less pupil than before. Now I understand...

The beast roared out while being in pain. It backed up while doing so, hitting a wall before climbing up it. It was but a moment when it finally glanced around with pupil-less eyes. I tried backing away from the area I was in, heading back to the water. The puddle shifted underneath my feet, splashing a little. Luckily I didn't catch the attention of it, but the beast did come down from the wall and looked around.

Suddenly I heard a familiar sound of a certain sewer slider and I turned my head, seeing Raph driving it. Boy he looked beyond mad. He was practically rage driving and poor Mikey was holding on for dear life. "Sis/Bella!" I heard them yell. "Guys?" I inquired stupidly. Of course it's them. Who else would it be? I thought, wanting to face palm myself. "Isabella, look out!" I turned to see the beast hiss in my direction.

I had to act fast, especially with the beast before me. It stood on its hindquarters, hunching over and it screeched loudly at me. The Mutant animal had lost its mind to its natural feral self. To the pain it endured with whatever it was injected with. The Mutant beast went on all fours and charged its large form at me. It roared out, echoing through the sewers. It pounced towards me and I happened to dodge in time but it just turned around and raised its claw at me. Without much thought, I took my kusarigama and swung the kama part of it in front of me.

The next thing I know... is the sound of liquid dripping. Looking up, I saw that my scythe had penetrated past its skin and into the chest. The beast looked down, finally having a little bit of pupil in his eyes, and he grabbed a hold of the kama. His claw was atop my hand. He didn't pull it out, no. In fact, he gladly pushed it in further, keeping a hold of it before looking to me. In the entire encounter, he finally spoke with a grin, "Th-... than..k... you.."

With that he fell forward, making me grab him. The weight was too much and I fell back onto the ground right before the water. The guys had finally got out and ran to me. Don and Raph pushed the Mutant off me. "Isabella, are you alright?" Leonardo asked. "It didn't do anything ta ya, did it?" Raphael added in.

I just stayed silent, looking at the dead-eyed Mutant with my kusarigama still embedded into it. I got on my knees and covered his eyes, making them close. "Mō itami wanai. (No more pain)." With that, I took my weapon out of it. "What'd ya say ta it?" Raph asked. I refused to answer and looked away from them before looking at his wound.

'It wasn't his fault. He was in pain. He was in so much pain that he lost his mind and he was obviously angry. Not at us though.' "Bella?" I looked up. Mikey's eyes were still wide. He was still shocked over what happened. "He was hurting... He didn't mean any harm... He was just.. in pain." I said. "He brought me here, but didn't do anything. He wanted help. He didn't say it nor did I actually see it, but he just wanted someone's help and I just.." I shook. "Hey, everything's going to be alright... okay, sis?" Mikey said. I wanted to believe him, really... but I couldn't get myself to.

"Can we at least fix him up before we go?" I asked. Raph huffed and Donnie already pulled out a needle and thread. "Seriously?" I hear the hothead say. "What? So I have medical things on me, what's wrong with that?" He asked. Raph looked away while Don and I sewed the wound close. What? I wasn't going to let him bleed anymore. He doesn't deserve it. After he was fixed up, Raphael, begrudgingly, and Leonardo set him back into the room. They leaned him back against the far side of the wall before leaving.

We all went onto the sewer slider and Raph took the wheel once more. "Now Raphie-boy, don't drive like a crazy lunatic." Mikey joked. "Zip it, Mikey." The hothead spat back. I sighed at them. One thought did bother me though. 'If he wasn't angry at us, then... who was he angry at?'

Author's Note: I finally came around to finishing the chapter. Again, I'm sorry it took so long. I didn't mean for it to literally take so long.

*- She got stomped on in Things Change by one of the Foot Ninja of you remember correctly.

Anyways, I hoped you guys actually enjoyed.. and if you must know, then you should know that Sister's Story only has a few chapters left before ending, but don't worry, we still have more adventures to have with her.
