Six: Never the same

As soon as Caitlin left the rooftop and Leo behind, she raced over to Stockman's lab. She gave him the blood on her shirt and told him to test it against her own.

''Now why would I do that for you? bzzt.''

''Because if you don't I'll tell Shredder you were working against him.''

''And what if bzzt, I tell Shredder first?''

''You tell him and I'll make sure to find the biggest fly swatter I can and squish you.''

Stockman stared at her. ''Alright girl bzzt, I'll see what I can do.''

She nodded and headed back home. She snuck back through the same window she went through and was about to go to her room when Karai appeared in front of her. ''Where have you been?''

Caitlin stared at her sister. ''I just went to clear my head.''

''And you feel better now?''

''Yeah I do.'' Caitlin didn't like lying to Karai, but she didn't think it would be a good idea to her that she had been talking to Leo.

Karai smiled at her. ''I'm glad.''

''I thought you'd be asleep by now.''

''I was until Shredder contacted me. He's sending me on a trip and won't be back for a few weeks.''

''Your'e leaving me?''

Karai put her hand on Caitlin's shoulder. ''Just for a few weeks. But when I come back we'll work together to take down the turtles and the boy. I promise.''

Caitlin gave her a fake smile. ''Okay.'' ''Don't worry i'll be back before you know it.''

They smiled at each other and Karai gave her a hug. ''Be careful Karai.'' '''I will don't worry Caitlin everything's gonna be fine.'' They both said goodnight and Caitlin went to her room and sunk to the floor. Something told her things weren't gonna get any better.

The next day at the lair, the turtles and April were having a sparring session. After all getting some well deserved rest, everyone was feeling better and it was time to train again.

April and Donnie were sparring, and so were Raph and Mikey while Leo and Master Splinter watched from the sidelines.

April was dodging Donnie's attacks while trying to land a blow but kept missing. ''Sorry April.''

He tried to hold back a little, and April came him again, but she missed and tripped. ''Sorry, sorry!'' ''Yame! April, Donatello that is enough.''

All five of them sat down and Splinter looked at April. ''You have improved much April. But you still need to work on not going for direct attacks and you should be more aware of your surroundings.'' April nodded, and Master Splinter looked at Donnie. ''And Donatello, if April wishes to improve you must help her out and not hold back. Otherwise, she won't be able to see if her training is helping her. ''Hai Sensei.''

''Good. Now my sons all of you will fight each other. Leonardo and Raphael and Donatello and Mikey. April you watch closely.''

April nodded as the turtles stood up and took their places. Leo took out his katanas, Raph his sais, and he charged for Leo. Leo blocked all his attacks, but Raph kept charging towards him. Leo and Raph kept fighting until Leo took both of Raph's weapons, but then Raph countered his attack and disarmed him to.

Meanwhile, with Mikey and Donnie they were fighting and blocking each others attacks until Mikey swiped Donnie's Bo staff out of his hand. Donnie charged for him, but Mikey held the staff out, tripping him. ''Aw man.''

Back to Leo and Raph who had gone back to hand to hand combat where they were both evenly matched, but then Raph got the advantage and flipped Leo over his shoulder.

''Yame. Well done Raphael and Michelangelo.'' Raph and Mikey helped Donnie and Leo up and the four of them went back to sit down. April was amazed. ''Wow that was pretty cool guys I'm impressed.''

Mikey smiled at her. ''Thanks April.'' ''Yes well done all of you. However you must continue your training so you can be ready for whatever Shredder has in store for you.''

''But we've already been through everything Shredder has sent after us'' said Raph, ''Yeah but don't forget that fight with Tiger Claw and Karai's sister'' Leo reminded him. Splinter nodded. ''I agree with Leonardo. To beat Shredder's new allies you must work together to destroy them.''

They nodded in agreement. ''Very good I will prepare some new training methods for you. But for now, you can relax for the rest of the day.''

Master Splinter went back to his room to meditate and the others went to go relax, but Leo grabbed April's arm. ''April can I talk to you for a minute?''

''Sure Leo what's up?''

''There's something I have to tell you.''

''Oh?''

''Ok so don't freak out…but I was talking to the girl who attacked us last night.''

April stared at him for a minute before grabbing a phone book that was on a table and hit him over the head. ''Are you crazy?!''

''Ow! why did you hit me with a phone book?!''

''because she's in the foot clan! what were you doing talking to the girl who tried to kill you?''

''I didn't intend on talking to her.'' He sighed. ''Let me explain. I went out for a walk after you guys fell asleep to clear my head. I didn't know I was gonna run into her it was an accident. But when I did, she tried to attack me and almost fell off the roof, but I caught her. She asked me why I saved her and I told her, and we had a temporary truce. That's when we started talking and I swear that's what happened.''

April took a deep breath and calmed down a little. ''Ok so what else did you guys talk about?''

''we told each other our names, and she said she was sorry and she really didn't want to hurt you, she told me her story and about her powers, and we even talked about Space Heroes for a while.''

April was surprised at that. But something told her that this girl was trying to use him. Just like her sister.

''Leo, just promise me you'll be careful. She's still part of the Foot clan and last time you tried trusting one of them…it didn't work out.''

''I understand April, and don't worry it'll be ok.''

*…*

Meanwhile, Caitlin was sitting on a rooftop. Instead of wearing her armor, she was wearing some street clothes Karai had picked out for her before she left on her mission. She was wearing long-sleeved black shirt, jeans, sneakers, and jacket. She had been on the roof for about two hours keeping an eye out for Chris, and just as she was about to give up, she saw Chris and Casey walking out of school so she decided to follow them.

''I still can't believe the principle gave me detention just because I talked back to the teacher,'' said Chris as he kicks a can nearby.

''Not my fault the teacher was being a lazy fat ass for not stopping those bullies picking on that kid.''

''yeah man, I can't believe I got detention either.''

''You got detention for playing hockey in the hallway and hitting the principle in the mouth,'' Chris reminded him. ''Although that was really funny.''

Casey chuckled. ''Yeah the look on his face. Priceless.'' The two continued talking while Caitlin looks on keeping her eye on Chris and remembering what happened last night.

''I will not fail…not this time.''

Casey and Chris go their separate ways and Chris heads to the park where he finds a nice bench to sleep on.

Caitlin wonders why he's sleeping there, but kept watching him.

Chris was still sleeping and she decided to get close to him. She carefully made her way towards him while making sure no one was around.

She was inches from him as she goes behind the bench and takes out a kunai knife.

She raised the knife and was about to stab him…but then she started thinking about last night. ''I-I can't do it.'' He saw that he was starting to wake up and disappeared. But not before she saw the colors of his eyes.

They looked familiar, but Caitlin ignored it and hid just as Chris woke up. Chris rubbed his eyes and looked at the time on his watch. ''Half an hour nap, not bad.'' He gets up and begins stretching. ''I better get going to my job, before the fat lard of a boss I have actually decides to fire me.

Caitlin watched him leave, and decided to follow him. Chris arrives a block away from the pizza parlor where April is waiting for him. ''Hey there, Red. What are you doing?''

''Just figured I walk with you to work. I have to get some pizza for the guys anyway.''

''You still owe money, remember?'' he said.

''Yeah,'' she reached into her pocket and handed Chris the money. ''Here.''

Chris takes it and they head towards the shop. ''So Red, mind if I ask you why those robots were after you? You guys never really did tell me why they are after you.''

April sighed. ''Trust me, Chris it's a long story.'' ''I got all the time in the world,'' as they turn the corner they come across the pizza pallor, still damaged from last night. ''Whoa, what happened here?''

''Um…'' April knew that this was where they found him unconcious but she didn't want to tell him.

As they approached the shop, Chris hears his boss yelling out his name.

''Chris!''

Chris lets out an annoyed groan. ''Yeah?''

''What in the world did you do to my store?''

''What do you mean I didn't do anything,'' Chris replied and muttered quietly. ''Yet.''

''Don't give me sass boy.''

''I wasn't, I didn't do anything,'' said Chris If I did do this there wouldn't be anything left but one brick.

April stepped in, ''how do you know Chris did it?''

''well, I don't have proof of seeing the kid do it, but he was responsible for keeping an eye on the store while I went to get some things from the store. So it is still his fault!''

''Okay first of all, what kind of idiot leaves a fourteen year old alone to run his store while the owner takes off?'' Chris asked. ''Secondly, I was out making a delivery because you told me to and by the the time I got back the place was already like this. So really the one who you should be blaming is yourself.''

''That's it. I've had enough of you. Your'e fired Chris.''

Chris stares at the owner with a dull expression, but then shrugs his shoulders. ''Eh, I never like working here anyways. Oh and by the way.'' Chris used his powers to tie up the owner and gagged him. ''You were a crappy boss anyways.''

Chris left and April followed him. ''Chris are you ok with being fired and all?''

''Yeah, the only reason I worked there was so I could get some money,'' Chris walks towards his moped and unlocks the chain. ''Thanks to my powers I was able to get a lot of tips, a lot from you mostly.''

''what are you gonna do now?''

Chris shrugs his shoulders. ''Maybe use my powers to do some good and help you guys take down the Foot…or just mess with some people and figure the rest out as I go.''

He then hands the bike towards his friend. ''By the way, mind if I keep this with you? I don't need it and I don't want to see a perfectly good vehicle be wasted on that fat lard.

''Sure no problem.''

April took off on his bike and left. Chris takes off walking since he was in no hurry to get anywhere. ''Well I may not have a job, but it doesn't mean this day can't get any worse.''

Caitlin was standing outside the alley and stuck her foot out and Chris tripped and fell to the ground. Chris slowly gets up rubbing his face. ''Okay, who's the wise guy?''

''Um sorry about that.'' Caitlin gave him a small smile and helped him up.

''Thanks who are you?''

Since Caitlin was undercover, she learned how to hide herself, she had put on a long denim jacket in the alley and put the hood up, and cleared her voice so he wouldn't recognize her voice.

''Name's Ariana.''

Chris extends his hand towards her. ''Nice to meet you Ariana, I'm Chris.''

''Ariana'' smiled at him.''Nice to meet you to.''

Chris stares at the girl almost as if he saw her before. ''You look familiar. Have we met before?''

''I don't think so.''

''You sure?'' Chris stares at the girl some more. ''You do seem familiar?'' Caitlin had her knife behind her belt and went to grab it, but Chris laughed. ''I remember now, you look like that girl I accidentally dropped a pizza on her head once,'' Chris begins to laugh harder.

''Oh man, she was so pissed at me…you are not her, right?

Caitlin relaxed and put her knife away. ''No I've never had pizza dropped on my head.

''Good, so you new around here?'' he asked.

''Yeah, I just moved here a few weeks ago.''

''That's cool, maybe we can hang out sometime so I can show you around,'' he suggested.

''Okay sure, but I would have to ask my dad, he's kind of strict.''

Chris begins snickering. ''I had a strict foster father, but let's just say after learning a neat trick I didn't have to deal with him or my foster mother.

Caitlin froze. Could we really be related? it couldn't be…

Chris noticed the girl looked surprised. ''What?''

Caitlin decided to ignore the thought so she wouldn't blow her cover. ''Um…nothing.''

''Okay,'' Chris's phone begins to ring. He takes it out and sees who it is. ''I have to go. Maybe we'll see each other again next time?''

''Okay, see you soon'' she said giving her a small smile.

Chris saluted her and walked off, but didn't use his powers. And as soon as he was gone, Caitlin's phone rang. She pulled it out of her belt and answered.

''Hello?''

''Bzzt hello Caitlin.''

Caitlin sighed. ''This better be good Stockman.''

''It is. I'm calling to let you know that the test is almost done and you can see the results when there done bzzt.''

''Excellent, when will they be done?''

''Soon, bzzt. I just have to finish a few things since Shredder needs me to do some mutagen testing.''

''Alright fine. But let me remind you that if you tell Shredder about this I'll tear your'e wings off understand me?''

''I understand.''

''Good. I'll be there in an hour.'' She hanged up the phone and took off.

*…*

Back to the turtles, they were all having a busy day at the lair except for Mikey who was playing video games. Raph and Casey were out having a race, while Leo was helping Donnie and April in the lab testing out the mutagen.

''You sure this will work?'' April asked. For the past hour, they had been trying everything to find a retro-mutagen for April's dad while Leo was trying to hold a mutated plant, which was hard because it kept hissing at him and trying to bite him.

Donnie decided to try using some of April's blood since they already tried everything else. ''Relax April it'll be fine and I'm sure I recreated it this time.''

''Uh, I'm not sure Donnie we've already tried nine times.''

''Ok, two of those times don't count and I'm sure it'll work this time.''

He finished the serum and walked over to the plant. ''Guys you may wanna take some cover.'' April and Leo got a table and hid behind it, and Donnie injected the serum into the plant and hid with them.

They watched the plant. It didn't do anything at first, but then it cried out in pain and it looked like it was turning back to normal.

''See I told-'' next thing they knew the plant exploded.

Donnie frowned. ''It didn't work.'' Leo shook his head '' I guess it's back to the drawing board.'' They stood up and April but hand on Donnie's shoulder ''it's ok Donnie you almost got it, and I'm sure you'll figure it out.''

Donnie sighed. ''I hope so.''

*…*

About an hour later, Caitlin had arrived at Stockman's lab.

''Is it done?''

''Almost just a few more minutes bzzt.''

Caitlin nodded and while she was waiting, she thought about her meeting with Chris.

It was so strange. Caitlin thought. ''I wanted to kill him…but I couldn't. Something about being near him felt familiar. Like I knew him.

Stockman's phone rang and snapped her out of her thoughts and Stockman went to answer it.''It's the Shredder bzzt. I have to take this once the test is over you can check it on the computer. He flew away and went to talk to Shredder.

As soon as he left the test results were finished. Caitlin walked over to the computer and looked at the results.

''Oh my God….'' so many things were racing through her mind that she wasn't sure what to think. She raced out of the lab and back to Shredder's lair. It was time to get some answers.

*…*

By the time Caitlin got back to Shredder's lair, it was almost the midnight. Clouds were gathering in the sky and it seemed like a storm was coming any minute. But that wouldn't be the only storm happening.

Caitlin to the door to Shredder's throne room and took a look inside. She didn't see anybody, not even Karai, so she walked in, slamming the door behind her and locking it.

Caitlin approached him as he turned around in his throne and sees her.

''What are you doing here girl? this better be good.''

''I want you to tell me about my past, my real past.''

''You have a lot of guts asking me that. But alright. You already know the story it's the same as I told you before. I was walking through the streets one night when I found you alone in an alley. You were barely three so I took you back to my home and raised as my own along with Karai.''

As Shredder kept talking, Caitlin tried to read his mind, but she couldn't get through.

What? how is it not working? she wondered. She stopped using her powers just as Shredder looked at her. ''By the way, why are you suddenly interested in your past.''

''Um, well I just curious, I'm sorry.''

He approached her and put a hand on her shoulder. ''Understood, now that is done I have a mission for you. You must go out on a mutagen run with Fishface and Rahzar and make sure they get all of it. If you come back without the mutagen, there will be consequences.''

Caitlin rubbed her scar from her last punishment. ''I agree to the mission father.'' Shredder nodded. ''Good now go.'' She bowed and left. Something's still not right. He's lying to me and next time I'm gonna find out the truth.

*...*

Later, on the rooftops, Leo had left the lair again to get some air. He kept running across the rooftops and headed to his usual spot and started thinking about Caitlin.

''Did you want to use your'e powers against us? I remember you saying that you didn't want to use your powers to go into my mind.''

''Alright, alright I really didn't want to hurt you and I don't have any control over any of my powers.''

''Well if you didn't have any control and didn't want to hurt me, then why did you do it?''

''Because. I can't go against Shredder's orders. ''The last time I did…well, let's just say I have the scars to prove it. That's why I went against you, but I did and still feel bad about doing it.''

Leo shook his head. ''I know she's not like Karai or the rest of the Foot clan..there's something different about her. I know it.''

''Sounds like someone has a crush, Leo jumps in surprise when he saw Chris standing nearby eating an apple. ''Wow, I didn't think I could scare a ninja turtle, how about that?''

''I wasn't scared and what the heck are you doing here?''

''Just hanging around,'' Chris sits down next to Leo and takes a bite out of his apple. ''So, who's the girl?''

''what girl? I don't know who your'e talking about?''

Chris pats his friend on the back gently. ''Leo, you don't need to lie to your good friend Chris. We both know you are obviously in love with the girl who was kicking your ass. You can tell me. I won't judge.''

''I still don't know what your talking about.''

''Whatever you say turtle boy,'' said Chris as he finishes eating the apple. ''So, are you guys out on patrol or is it just you going out for a walk?''

''It's just me, I felt like I needed to get some air.''

''Same here, especially since I got fired,'' said Chris.

''What? how did you get fired?''

''My former boss thought I trashed the store last night. So he blamed me for it and fired me,'' he answered. ''The good news for me is I don't have to work anymore. The bad news for you guys is no more fast pizza delivery.''

''Oh man…sorry about that.''

''It's cool,'' Chris throws his apple away and they hear it hitting metallic. ''I wonder what I hit.''

They go down to check it out and see it's a Foot bot.

''Isn't this one of those robots you guys fight?''

Leo took out his swords. ''Yep.''

''what's it doing out here alone?''

Leo noticed a building nearby with a truck and figures the foot are up to something.

''Whatever it is, it's not good. Let's check it out.''

Inside, Caitlin is watching as the foot bots are ordered by Xever and Rahzar to move the crates of mutagen around.

Ugh this is so boring…Caitlin thought. And as she kept an eye on them, her mind went back to the test results. Maybe there was a mistake…there's no way it could be possible…

''Caitlin!'' Caitlin snapped out of her thoughts and saw Fishfasce and Rahzar staring at her.

''The last of the shipment has been loaded.'' ''Good. Now take the truck back.'' Rahzar growled at her. ''I don't see why we have listen to a little girl.'' ''Oh shut up and get that truck to Shredder before you mess it up.''

As they get in the truck, Caitlin hears something coming nearby. She throws a knife near where the sound is coming from and it cuts through the chain causing the crate to hold it to fall.

Leo comes out from behind some crates before the big one crashes on him. ''Get him!'' Fishface shouted, but Caitlin held them back. ''Never mind him get in the truck. ''Foot bots! attack Leonardo!''

They begin attacking as Leo fights them off. Caitlin watches by while they fight biding her time to get involved. Once Leo takes down half of them down she uses her powers and attacks him.

He recovered and she tries using her powers again but Leo threw a shruniken causing her to loose focus. Caitlin glared at him and took out her knife to defend herself.

Leo moved in and attacked her. ''What are you doing?!''

''what does it look like? I'm doing my job.'' She kicked him in the jaw.

''You don't have to do this Caitlin. Just tell me what's in the truck.''

''Ha! I don't think so. You shouldn't have come to fight alone.''

They continued fighting until Leo gains the advantage, but Caitlin used her powers again to throw Leo towards some crates and then lifts him up before using her powers to grab some chains then tied him up.

''Let me go!''

''No. I'm sorry Leo…I'm sorry it came to this.''

Just as she is about to use her powers to take Leo out she is hit by something that knocks her into some more crates. She looked at where she got hit and sees Chris.

''Hey ninja girl, back away from my turtle friend.''

Caitlin looked at him shocked. ''No way…''

Chris helped Leo up and hands him his weapons. ''You may want to get your brothers.I stopped the truck and tied up the Foot guys, but there is a truck full of glowing goo that I think you guys may want to check out.''

Leo nodded but hesitated to leave. But he knew he had to so they could get ready of the mutagen. So he left leaving Caitlin to fight Chris.

Chris turns towards Caitlin who makes her way up. ''So, here we are again. Round two, this time though I won't let you get away.''

Caitlin was suddenly really scared, but she tried not to let it show as she took out her Juij-ken.

''We'll see about that.''

Chris uses his speed to kick Caitlin in the gut knocking her across the floor, but she recovered and jumps out of the way when Chris went for another attack.

She used her powers to lift him up in the air, but he broke out of it using his speed.

''That is not going to work on me twice.''

She growled in frustration and started using her powers to lift crates and tossed them at him.

Chris dodges them and sticks his tongue out. ''You missed!'' He fails to see one being thrown straight towards him and it knocks him through the wall outside. ''Nice one.''

Caitlin smirked. ''Thanks.''

Chris grabs some rubble and throws it at her super fast. She dodges and see they made some holes in the crate . She's uses them to throw them at Chris, who dodges them. He runs back into the warehouse and begins running around Caitlin creating a whirlwind. She begins to be lifted into the air as Chris continues running.

She begins to concentrate and uses her powers to break one of the beams in the building in the building and tossed it in Chris's path tripping him and breaking the whirlwind, but she crashed right through the crates.

Caitlin groaned in pain. ''Ow…''

Chris gets up and see his reflection in the mirror seeing his contact is out. ''Damn, looks like I'm going to need a new one for my eye.''

Caitlin got up and faced him. ''Oh my God…''

''What?'' he then faces her and is shocked. ''What the?'' Both stare at each other seeing their eyes. Caitlin knew now that his eyes were like hers and he sees her eyes are like his.

Caitlin was speechless she didn't know what to think.

''Chris!'' Chris heard the turtles calling out for him, but when he turns around to Caitlin he sees she's gone. A minute later, Raph and Leo came to check on him. ''Chris? you ok?''

''I think so,'' Chris continues staring where Caitlin was at looking confused. Raph looked at him with concern. ''You sure?''

Chris nods. ''Did you guys get the cargo?''

''yeah we got it.''

''Good, then let's go then.''

As the begin to leave, Leo looks around thinking about Caitlin before following the others.

Caitlin was nearby watching and began to think about what just happened. Now confirming that the test results were true and she beginning to have her doubts.

She suddenly saw flashes before her eyes of a woman that looked a lot like her, a home on fire, and a large figure attacking the woman as she screamed out in horror.

She shook the thoughts away and decided it was time to figure out what she was going to do with information she has.
