Leo's P.O.V. -
"C'mon guys. We need to find out what the girls are up too!" I whispered as we followed them through the sewers. "Yeah, well, whatever it is that they're doing, Master Splinter knows about it." Donnie said, catching up next to me. "Hey, where'd they go?"Mikey asked, and we all skidded to a halt. "I don't know, but they couldn't have gone far." Raph said, crossing his arms. "C'mon. They are fast, I gotta give 'em them that." I said, and with that, we followed the pipe.

Abby's P.O.V. -
"Did we lose them?" Maddie asked. "I don't know. They'd probably be looking for us." Esha said. "Let's hide in here." Vicky said, pointing to a smaller pipe. We were able to fit in, then we heard the guys coming. "Do you think they went up here?" Donnie asked. "Probably. I'll go first." Leo said, climbing the ladder. I felt so bad, because that was the manhole just in front of the warehouse. 'What if they find our instruments? They're gonna ruin everything!' I thought to myself. Then I had an idea. When Mikey finally got up there, I jumped out and went up the ladder. My friends followed me, and I placed the manhole down loudly, and purposely. The guys looked at us, but we pretended we didn't notice. We ran the opposite way, and up onto the rooftops. We knew the guys were following us, but we kept going. This is exactly what I wanted.
We jumped across various buildings, flipping and doing tricks. We did that until we came across a building with a large roof. "Perfect," I said, "We'll practice here." I winked at them and mouthed 'karate'. They nodded and agreed. I could feel the guys' eyes on us, and I turned around only to see nothing. I smiled to myself, because I knew exactly where they were. They were behind that airvent over there. I went and stood in front of the girls and they lined up in front of me. "Okay, today we'll start with the basics. Stomach level punch, Kamei!" I ordered, and the girls did a punch towards the stomach level area. I walked around to see if they were all in the perfect position, and they were. So I stood in front of them and did mirror image. "We'll do hard and fast." I said. "Hai!" Said the girls in unison. "Ichi, Ni, San, Shi, Go, Roku, Sich, Huch, Kou, keyai-Jou!" "HIYA!" We all shouted on the last count. (Yes it is in Japanese. I do karate.) We went through all the other punches and blocks like this, and I could still feel the guys watching us.
"Great! Now let's do kic- I don't think we're alone." The moment I said that, a bunch of foot ninjas came out of nowhere. "You again? Gee, now it's just annoying." We attacked them, and knocked them all out. We then 'disappeared'. The guys looked for us, but didn't leave their spot behind the vent. We landed silently behind them, and they hadn't noticed us yet. "Ahem!" I said. They looked at us, surprised. We had our arms crossed, and we made ourselves look really angry. "Uhh-" Leo started to say. "We don't want to hear it! Why did you follow us, even if we left it clear that we didn't want followers!" I yelled. "S-sorry. I guess th-that we were just c-curious about what you d-did." Leo said. "Yeah, and what's with all the karate crap?" Raph asked. "Ok, our karate is not crap. How would you like it if we said that your Ninjitsu was crap?" Vicky said. "Okay, point taken, but is this really what you've been doing all this time?" Raph asked. "Well, kinda." Esha said. "You know, you can train with us instead of coming all the way out here." Leo offered. Our eyes widened. "You mean we can train with you guys in the art of ninjitsu?" I asked, basically the same question me and my friends were all thinking. "Well, yeah-OOF!" Leo exclaimed. We all hugged a turtle each. I hugged Leo, Maddie hugged Mikey, Esha hugged Donnie, and Vicky surprisingly hugged Raph. All the guys blushed, and me and my friends squealed in delight. "Race you all back!" I said. And we all took off.
Obviously I got there first, as I was totally part cheetah, the fastest animals on the planet! My friends came in closely followed by the turtles. We all caught our breath, and went into the dojo. We went in and knelt in front of him. "What is it, my sons and daughters?" Splinter asked. "Well, Sensei, we were followed by the guys, and they caught us practicing our karate." I said. "You practice karate?" Splinter asked. "Yes. Abby did before any of us. She did it before we even met!" Vicky said. Maddie added "She is the most skilled out of all of us." Master Splinter looked at me. "Is this true?" he asked me. "Well, I have only been doing karate for five years, or so. But that's not the point. The guys offered if we could train with them in the art of Ninjitsu. Is that ok?" I asked, and me and my friends all pulled the cutest face we could, and now it was even cuter now that we were part cat. "Very well. We will start in the morning." Splinter said. We all got up, all walked out of the dojo. "YES!" We all yelled simultaneously.
We were so excited. We finally got to train with the guys! Not that it's a big deal or anything... Who am I kidding. This is awesome! "Will we get our own weapons?" I asked, calming myself down, and not really directing it to anyone. "Well, yeah. I've never actually seen a ninja without a weapon before. We'll find yours' tomorrow morning." Donnie said. "That is SO COOL!" Esha said. "Tomorrow morning? For how long?" I asked, a bit of concern in my voice. "Only up until lunchtime. You're not going anywhere, are you?" Leo asked me. "Well, yes but you are so not following or I will not be afraid to use this!" I said then I flipped over him and grabbed one of his katanas. He turned around, not knowing that I had took it. I pointed it to his face, which surprised him. "Ha!" I said. "How did you-" He attempted to ask, until I cut him off. "That's what you get when your me!" I said, smirking. I gave the katana back to him, and I went into our room, with my friends following, giggling.

Leo's P.O.V. -
"Dude! You just got told by a girl!" Mikey said. I put my katana back into it's holder and said "Ha ha, Mikey. But what did she mean when she asked 'for how long?' I mean, she should know. I still think that they're hiding something from us." I said. "Yeah. I thought Master Splinter knew about whatever they're doing, but he didn't know that they practiced karate." Donnie said. "Well whatever it is, I wanna find out what it is." Raph said. "Well, I think that it has to do with that warehouse." Donnie said. "I think that they knew we were following them, so they might've been leading us away from something." "Girls and their secrets." Raph muttered. "Well, c'mon, what're we waiting for?" I asked. I turned around to see the girls sneaking out. "Ugh. Not again." I said to myself.
We followed them to the same manhole as earlier today. They went up, and closed the manhole. We waited for a bit, then I went up and snuck into the warehouse, with my brothers closely behind. "C'mon girls!" I heard Vicky say. "Um, Vic." I heard Abby say. Crap. She probably knows we're here. "Ugh, what is it now, Abby?" Vicky asked, obviously annoyed. "I think we were followed." She said, getting quieter. I heard her footsteps come towards us. 'Crap! Now she'll hate me forever!' I thought to myself. She came around and I prepared for the worst lecture of my life, part two. "Guys!? I thought I specifically told you NO FOLLOWERS!" She yelled. "Who is i- Oh. Them." I saw the others come behind her. 'Great!' "Seriously! It's almost like you don't trust us!" She yelled. Her tail was swaying like crazy and the others' were as well. "Well, we just want to know what you guys are up too." I said. "Ugh! You are so annoying! Don't you get it? we don't want you to know! Why can't you just leave us alone for at least an hour!" She yelled, practically screaming. "I'm sorry that you just keep running off! What are you hiding in here anyway?" I asked, trying to walk past her. She stopped me and said "It's none of your business. Now GO AWAY!" She screeched, making the walls around us shake a little, and the glass threatening to smash. "Already gone." Mikey said, disappearing with Donnie and Raph. "Ugh! I will find out eventually!" I said, and I went back down the manhole.

Abby's P.O.V. -
"Esha, you have that system ready?" I asked. "Yup. If anyone tries to break in, they'll end up in that box over there." Esha said, pointing to a big, see-through plastic box. "Are you sure it works?" Vicky asked. "Already tested." Esha pointed over to the box, and it showed three rats and a cockroach in it. "Okay, I get it. Do you think we should go back now?" Maddie asked. "Yeah probably. Master Splinter would be worried." I said, and we walked outside. Esha turned on the security system. We went down the manhole. Maddie asked me "What about the guy-" "Please don't mention them" I said, trying not to sound too angry. "I'm really not in the mood for them. Especially Leo. Ugh! He is SO annoying! Sometimes even worse than Raph!" I yelled. "Well I guess I gotta try harder then." I turned around and towered over Raph. "What are you doing here!" I asked, yelling. I looked in his eyes, and saw fear. "It was Leo's idea, I swear!" he said. I scoffed and kept walking.

Raph's P.O.V. -
"Gee, is she always like that?" I asked Vicky. "No. You guys really made her upset, and when she's upset, we're all upset." She stormed off next to Abby. "Girls." I muttered to myself. "What did you say?" I turned around to see no-one there. I looked back and nearly jumped out of my shell to see Esha and Maddie standing there with their arms crossed and looking coldly at me. "Um, nothing." I said. "You know what. Abby's right." Esha said. "About what?" I asked, not understanding. "She's right about you guys. You are always nosing around and are really annoying." Maddie said, and they caught up with Abby and Vicky.
"Anything?" Donnie and Mikey came up behind me. "Only that we just entered a whole world of pain." I said. "Uh-oh. Seeing what happened before, I guess you mean literally, a world of pain, right Raph?" Donnie asked me. "Yup." is all I said. "Who cares. I don't. We've been through worse." Leo said and he came up to us. "Yeah, I've never seen walls shake and glass nearly shattering because of someone yelling. I don't like this. I'm not spying on them, ever again." Mikey said. I've never seen Mikey so serious before, and that came out as a shock to everyone. "Me either." I said. "I agree with them." Donnie said. We all looked at Leo. "Fine. But I will find out eventually, with you or without you. He walked off, and we followed. It was a silent trip home.

Abby's P.O.V. -
When we got back to the lair I went straight to the couch and burst out crying. I had a huge headache, and I couldn't focus properly. My friends came around me, trying to comfort me. Then I felt them, their presence. The guys saw us on the couch, and then they went straight the kitchen. Master Splinter came out of the dojo. "What is wrong, Abigail?" He asked me. "It's the guys. They just can't leave us alone to practice. They are gonna ruin the surprise!" I said, still crying, but keeping in my temper. "Maybe you should cool off some steam." Master Splinter said, motioning towards the punching bag. I got up, walked over to it and punched it once, so hard that it already flew off the chain. "HEY! I had just got that fixed!" Raph glared at me. I glared back. "Well then next time it will be you." I said. Suddenly, I felt my limbs go numb, then everything went black.

Leo's P.O.V. -
She collapsed. Just like that. "Abby!" The three girls yelled, worried. She wouldn't get up. "Donnie, do something!" Esha yelled. "Someone get her on the couch." Donnie asked. I ran over and picked her up carefully, feeling her limp body in my arms. Her breathing was shallow. I placed her very carefully on the couch. She still had color to her face and that was a good sign, at least. "She seems to be dreaming about something." Donnie said. "Not again..." I heard Vicky say. "Huh? What do you mean, not again?" I asked. "Uh, nothing!" Maddie said, backing Vicky up. "She just needs to rest. She'll be up soon." Esha said, and we all went to do our own thing.

Abby's P.O.V. -
Water. It's everywhere. There's a ship off in the distance. It has the foot logo on it. It was sailing away. I swam towards to boat, which has now disappeared. I could hear a deep evil laugh. After that, all I heard was the ocean waves. I swam and swam and swam for what felt like hours, but there was nothing but endless water. "Leo?" I yelled. No response. I felt so lonely. I felt so lost. I felt that part of me was missing. Something grabbed me and tried to pull me under the water. With all my strength I was able to say one last word before I was completely under. "LEO!"
"Leo!" I yelled. I woke up on the couch, and Leo came straight to my side, soon followed by my friends.
