Chapter Three
On My Own
(Karai's POV)
"So, your dad's not too mad?" I asked.

"Nah, he figured out that I was a vigilante a little while back. He's used to this by now. I did have to make up a cover story, and then I had to spend a little while telling him not to call the police, but everything's fine now. Um...any luck yet?"

I sighed. "No, no luck yet." I said into the phone. I had left the city a few hours ago. I had taken a motorcycle from Shredder's lair and gotten on the road, but then I came to a very depressing realization-my brain must have been so scrambled and crazy last night, that I hadn't even remembered that I didn't have the slightest idea where he could have gone. I drove around the entire city for two hours until about five a.m., until I concluded that he had fled by now.

This was not good at all. Not only did I not know where he was, but he was probably wandering around mindlessly. The hopes of seeing my brother alive again was growing slimmer and slimmer by the second. I didn't have any clue where to look.

"You don't think he went into one of the rivers, right?" Casey asked through the phone. "I know that some snakes can go into water. I'm not as dumb as Donnie made me look." I tensed up when I heard his name. Casey might have known from my silence. "Oh! Um..I'm sorry Karai! I didn't mean-"

"It's okay!" I cut him off quickly. "It's okay. You can say his name, I don't mind. Now, how are the others doing?"

"Well, I don't know. I left pretty quickly after you to go back home, but I checked my phone earlier and I saw a bunch of missed calls and texts from the guys and April. They must be livid with you by now. Well, Raph must be at least, because most of the missed calls and texts were from him."

I sighed. They really didn't trust me anymore. Maybe even Mikey was convinced that I was the evil one. "Okay Casey, I really have to get going again. I'll talk to you later."

"Okay. Talk to you later!" Then I heard him hang up.

Taking a deep breath, I looked around. I was sitting on the motorcycle, on the side of the road where I had stopped to talk to Casey. I was on the highway, at least an hour or two away from NYC. There wasn't much, just the highway and some trees on each side of the road.

How far exactly could snakes travel in one night? Well, since he's recently been mutated, he would have a lot of brand new strength to use up, so he could have gotten far, but not too far. He would have to rest. I just hoped I was getting close.

It was seven a.m. now, and the sun was up. There were cars going by, back and forth, just normal people doing everyday things. What I wouldn't give to be one of them. No, what I wouldn't give for all of us to be like them. No Kraang, no Foot Clan… and absolutely no trace Shredder. We could just be a normal family on another ordinary day. Not sulking with one of us transformed and running wild with half a normal mind, while his sister has to go find him and bring him home, to prove that she's not the villain in this distorted story.

His sister. I just realized how I had worded that. I had called myself Donnie's sister.

Images of the worn journal, and the night I learned the truth about my parents, and last night's fight all went swimming through my head until I was dizzy and had to sit down. I guess I had the right to. Until now, I hadn't really had time to think about what was happening. I was a big sister now. I had four younger brothers to defend and protect now, like a sister should do. And no matter what, I wouldn't let that four morph into three brothers. No matter what I had to do, or sacrifice.

To think...me, a sister. Karai never wanted siblings, ever. Now as Miwa, all I want is to see them all together again, laughing and crying with joy at being reunited. Karai won't be coming back, ever. Miwa has permanently taken her place.

I heard a car pull up at least eight feet away and someone got out. I realized that I must have looked pretty suspicious sitting on the ground. "Are you okay, miss?" someone asked. I looked up to see a tall man in a plaid shirt, with kind brown eyes. I nodded. "Yeah, I'm okay. I just needed to rest a minute." I said.

Suddenly, I heard a small voice yell, "Daddy! What's going on?" The man and I both turned to the white pickup truck, where two little girls were getting out. They only looked eight and six. "Nothing Mallory, I was just making sure this young lady was okay." said the man. The eight year old nodded, then turned to me. She had her father's brown hair, but she had hazel eyes. "You have pretty hair." she said to me.

I blushed. "Um, thanks." The little girl smiled. Her father turned to me. "My name's Bryan Henderson. These are my daughters, Mallory and Bonnie." The littler girl, Bonnie, waved at me and said "Hello," very quietly. She has sandy blond hair and her father's brown eyes. "We live near here." Bryan continued. "I just wanted to make sure you didn't have that weird virus that's been going around since last night." My head perked up. "Wait, what virus?"

"Oh, it's this weird things that's been making people pass out. Someone's saying that it's going through the water, and the girls and I were getting bottled water for today until someone figures out what's going on. People around here have been going to the emergency room left and right. We know this because my wife Kendra is a reporter around here for the local news, and she's gonna be doing an interview on it with someone in the hospital tonight." Bryan explained.

Well, if I remembered right, viruses don't go through water like that…..but I know something else that does. I overheard Shredder talking about it with Stockman right before Donnie...well, you know. But that didn't matter anymore. Because Bryan may have just accidentally directed me straight to my little brother.

"Um, I have to go." I said, heading back to the motorcycle. "One more thing though. How many people are experiencing this problem?" I asked. Bryan thought for a second, then said, "It's happening most to people all the way up in Northampton, and that's a little over an hour away. People are saying that it's most likely the source of the problem, because it's so powerful there, that some people in the hospital in Northampton are hallucinating! They're saying something about seeing some long, scaly white monster with fangs right before being struck by the virus, but no one else has reported anything."

I nodded seriously, but on the inside, I was getting excited. "Okay. Thanks, Mr. Henderson! Bye girls!" I said, hopping back on. Mallory and Bonnie waved as I drove off.

About an hour later, I was in the same town that Bryan was describing to me. I drove around, looking for a place that Donnie could have been hiding. But nothing looked as if he would be there. He may have just been mutated, but that doesn't mean he was still smart. He would have to find somewhere clever to take cover.

And it turns out, that it was a few miles away from town. But not a likely place that I was expecting, because as I drove up the driveway, I saw the mailbox.

O'Neil.

For a second, I just sat shocked. If he was here, which seemed to be exactly where the 'virus' was coming from, did he know to come here because he... remembered April? Did he recognize that she had been here? There was only one way to find out. I parked outside, got off the bike, and began to circle the farmhouse. It was pretty big, with three floors and a large yard surrounding it from all sides. It was sitting in a clearing, which was surrounded by woods. I checked the doors and windows, but everything seemed to be locked. But when I checked around the sides of the house again, I found something I had overlooked. A hole, leading to what looked like a basement wall. And in the wall, was another hole. It looked like someone bashed their way through, headfirst.

I suddenly feared for my brother's safety. If Donnie had made that hole in the basement wall, then he didn't even have enough sense left to find the entrance. That also meant he probably couldn't find the exit either. Could he be trapped up there? Or worse, injured? I had to get in.

Luckily, the hole wasn't to small, and I slipped through with ease. The basement was almost entirely dark, besides light spilling in from the door to the stairs. I ran over to the stairs and climbed them two at a time. The inside of the house was dark (and a little dusty), and the floorboards kept creaking under my feet with every step I took. I looked around for a light switch, and finally found one for the small chandelier over the staircase at the entrance.

As I was turning on the lights downstairs to get a better view, I suddenly heard something. I stood frozen, waiting. Then I heard it again. A scratching noise. Directly over me.

I flew up the stairs in seconds.

And there he was.

"DONNIE!"

(Casey's POV).
Okay. Now I know I wasn't supposed to spy on anyone associated with The Foot Clan, but what was I supposed to do? Sit around and wait for something to happen?

Sorry, but that wasn't gonna sit with Casey Jones.

Geez, no wonder Red's always saying I was always brash and cocky. This took up half my pastime! Still, I couldn't resist. After school, I took a shortcut through the sewers to get there. I then waited until the right time to sneak in through an open window. I sat on the window ledge, listening. At first, nothing, until I heard a door slam open.

And in came the Shredder himself, with Tiger Claw following right behind him. Rahzar, Fishface and Stockman were also entering. "Master Shredder, I assure you that we have Foot-bot soldiers scouring every part of this city! Karai couldn't have gotten that far!" Tiger Claw said. Shredder turned to him. "I don't care, if she even stole one of the motorcycles downstairs and is out of the city! Do not stop until you FIND HER!" he shouted. Then he turned and sat down on his throne.

Fishface turned to his master. "Well, at the very least Master Shredder, we have one less reptile to deal with." Then he began laughing. "Did you see how hideous it was after taking a dive into the mutagen?! It was worse than me!" He then pretty much fell over laughing as Shredder's henchmen also began chuckling and throwing all sorts of nasty insults about Donnie and snakes around the room.

How I wish I could have fried Fishface's tail, right there and then. Insulting Donnie was taking it too far, and it made me sick. Luckily, Tiger Claw didn't seem to think it was funny either, because he held up his paw and everyone shut up. "What is it, Tiger Claw?" asked Rahzar.

"I smell an intruder." he said. Everyone jumped up and began searching the building. Uh oh. I couldn't leave now. I guess I would have to wait for them to leave, and then make my escape. I then silenced my phone and waited for everyone to leave. The only problem was that more Foot-Bots began to pour into the room, which halted my exit even more. If I ever found the place where Foot-bots were made, I would make sure to bring extra exploding hockey pucks.

Speaking of which…

I heard a BANG! below on the ground, and I saw a small, but fiery explosion. I realized that my bag was open, and that one of my exploding hockey pucks must have slipped out of my bag while I wasn't looking. Unfortunately, the Foot-Bots looked up and saw me. "Aw, crud." I said. Then I jumped down from my ledge and shouted my catchphrase; "GOONGALA!"

This was going to be a long rest of the day…

(Karai's POV).
The first thing I saw was that he had blood on him, and he was unconscious. That had frightened me.

I managed to haul him down the hall to the bathroom, where I gently placed him in the bathtub and began to clean off the blood. I also got out a first aid kit that I remembered packing and got out its contents. Then I looked over his wounds.

He had a large lump on his head from boring through the wall, which was swollen. Multiple cuts and bruises from last night covered his body, and in many places, the scaly skin was torn severely. He would need stitches. I've known how to stitch up a wound since I was nine, when I started doing it to myself after I'd have a bad training session.

Pretty soon, he had stitches and bandages on his face and head, arms, torso, and tail. Then when I took a better look at his tail, I realized that it was twisted at an angle. A bad angle. It was broken. If he was still normal, that would mean that both legs were broken. One thing was for certain, he wasn't getting out of here anytime soon. We were stuck here for a while. I wrapped his tail in bandages too. After I had covered all his injuries, I managed to get him back down the hall and into the master bedroom. I laid him down on the bed and pulled the blanket over him up to his shoulders.

He seemed so...peaceful. After what he had to go through last night, he deserved it. He was innocent. Too innocent to deserve having been caught up in Shredder's plans. The last thing he needed was to have mutagen burned into his DNA for a second time in his life, and be transformed into an almost insane creature. I just prayed that he would know who I was. I waited hours for him to wake up. He must have been up all night, probably panicking and in pain. So much pain. It was a disgusting thing to think about.

It was maybe ten hours after I had found him when I felt him stir. Gently, I sat up, letting his head rest on my lap. He stirred more when I began to stroke the back of his head. I didn't know why I did that. Maybe it was to comfort him, or me, or both of us. Either way, it worked. We were both very calm when he finally opened his eyes.

"Donnie?" I asked when I saw the jade green eyes open once more. He blinked a few times, then looked up at me. "Donnie, are you okay?" I asked. "It's me, Karai. I came to find you..." More blinking, then Donnie inched himself a tiny bit closer to me. "...Sissy?..." he hissed.

That sent chills up my spine. He must have not been able to pronounce my name right then, but still, what I was thinking about earlier forced it's way back into my brain again. I was Donnie's sister now. Then I gritted my teeth. If I was going to be his sister, I should have been acting like it!

I looked down at him and smiled. "Yeah. Sissy's here. Sissy's not going away." I muttered quietly. He only stared for a second, then he shot up suddenly and kind of wrapped himself around me, tightly. I gasped at the sudden movement, then relaxed. He had missed me. He knew who I was. I could tell by the way he was nuzzling my cheek.

"...Others…..Okay?..." he asked. I felt my heart sink. I remembered who it was exactly for getting Donnie into this mess. "Yeah, they're okay. Angry, but okay…" I trailed off. Donnie took that as a solid yes, then began to sit up. I stared blankly as the scaled ran under my hands, then I got the courage to continue. "By the way...I'm sorry." I said. Donnie looked at me and cocked his head to the side. "For getting you into this mess."

Donnie quickly moved back over to me and leaned his head on my shoulder. I had jumped again at the fast paced movement, but I could tell that I was going to get used to it. "...Not…...Your…...Fault,…...Had….To….Do….It,...Only…..Right…."

"I know it was the right thing to do for me, but that caused you to fall in. I'm so sorry Donnie. I should have been quicker." I said. Donnie firmly placed the two snake heads at the ends of his arms on my shoulders, and I had to look him in the eye. He was being firm with me. He wouldn't have forgiven himself if he had let me be mutated instead of him.

Oh Donnie. Always putting himself before others. So protective.

Suddenly he hissed and I jumped up to see if something was wrong. "Are you okay?!" I asked, getting ready to defend my little brother. Then I saw what was wrong. I had completely forgotten about the broken tail. I went over and draped it out on the bed flat. "It's broken." I explained. "We're not getting out of here for a while. I'm sorry." I visibly saw him wilt. "I feel like that's my fault too." I said. Donnie shook his head.

"I know. I know you keep saying it's not my fault but...I just feel like such a failure right now." I said. I sat down on the bed and rested my head on the pillow, facing Donnie. "Have you ever felt like you just were utterly useless as a sibling?" I asked. "Because that's how I feel right now. I've been feeling it all day."

Donnie's face clearly said one thing. 'I get that all the time.'

I sighed. "All I want is to be a sister. A real one. A better one. Much better than I've been in the last few months." I told him. He frowned sadly, then pressed his forehead up to mine. "...You…..Already….Are….." he said.

I felt myself tearing up. I tried drying my eyes as I muttered; "Thank you, Donnie. And I promise that I'll be Miwa for you. I'll be the best Sissy you can ask for, more than that even. And I promise, that I'll never let anything like this happen to you, Mikey, Leo, or Raph ever again. I promise..."

My baby brother was okay. That was all I needed to know to be at peace.

A/N.
Well, I felt like that might have been a bit rushed, but other than that, it's okay. Besides, I had a hectic day (which included my sister and my mom going to see Dear Evan Hansen on Broadway, and me staying up until two a.m., then waking up at ten a.m., but on the bright side, I got money for tickets to see Come From Away with my dad!). So all in all, it was a crazy week for me (getting this chapter finished in six days), so that's why it might not be as good quality wise. But still, I really loved doing this chapter.

Okay, I think that's just about it. I hope you enjoyed this chapter of Sissy (and now I think you know why I named this story Sissy), and once you're done, leave a review, favorite, follow, and as always…

Stay tuned! ;)
