Leo's Pov...
I was really worried about Callista. She still hasn't waken up since Shredder injected her with mutagen and Calli was continuing to change from a human and into a turtle. Her whole face has now turned green and it was now spreading down her neck and arms. It would only be a matter time before her mutation would be completed and she would no longer be human and she would be a cold blooded reptile like me. All on my mind was of how Calli would be reacting to her mutation and how she would react towards me since I didn't protect from her Shredder.

I stroked my hand through Calli's beautiful hair feeling it starting to fall out rapidly through my fingers. I sighed quietly and I looked down at Calli seeing her mutation was starting to take effect. Her beautiful face was extending out making a snout and I looked down at her already green hands and I saw her fingers starting to close together into three fingers instead of five. Calli continued to lay motionless as her mutation advanced. I started seeing Calli rise up from the couch and something began to bulge out from the many thick blankets she was covered in and I started hearing the sound of clothing being ripped. I knew that Calli was started to form her shell on her back. I then heard the sound of more clothing being torn in front of her and that's when probably she was starting to form her plastron. I then looked down at Calli's legs and I saw her feet were now turning green and her toes began to close together and grow bigger, and now it was just two toes on each of her feet.

I then looked at Calli's face seeing now her mutation was completed. She was no longer the human she was before, she was now a cold blooded terrapin like me. I just couldn't believe that this happened, it was just too much for me to bare. I couldn't look at Calli without feeling the guilt rip my heart into huge pieces.

"I'm so sorry Calli", I said, softly

I kissed Calli's forehead softly stroking her cheek and she didn't respond to my touch. I sighed and I stroked her head softly, then I slowly got up and I slowly walked away from Calli's body and I quickly climbed out of the lair and I ran out of the tunnel, and I ran to Central Park. I continued to run through the quiet park but then I tripped on a tree root branch, that was the same oak tree that Calli and I met the day after we met. I landed on my plastron hard and I grunted in pain, but the pain didn't matter to me. My hands balled up into fists as I sat up against the trunk of the tree. Tears then began to form in my eyes and I then started to cry softly, all my mind was Calli.

Calli's Pov...
I moaned feeling my eyes slowly fluttering open and I looked to see I was back home in the lair and I was in the living room. I looked down and saw I was wrapped in many thick blankets. I sat up on the couch as some of the blankets slid off from my shoulders and I didn't feel cold anymore when Shredder injected me with the substance and now I felt very warm. I looked around seeing I was alone in the lair and I unwrapped the blankets from my body but as I unwrapped myself I looked and gasped as I saw my hand.

It was not my hand as it was before. It was green and I had three fingers instead of five and I looked at my other hand seeing it was the same and I saw my arms were green too. I looked at myself with fear and confusion as I was not understanding what was going on. I slid out of the blankets and I immediately got off of the couch and I looked around for anyone in my family. "Leo! Raph! Donnie! Mikey! Splinter! Anyone?", I called out

"Calli?", someone said

I turned and I saw Mikey come out from the subway car. He then just looked at me stunned and I came running towards him. "Mikey!", I said, hugging him tightly

He hugged me back, but he still had his look of shock as he looked at me. "Calli! You are awake finally! We were so worried about you!", he said

"Mikey something is wrong with me I'm all green everywhere!", I said

"Calm down Calli", he said "Something happened to after Shredder attacked you"

"What do you mean?!", I asked

"Calli?", someone said

I then turned and I saw Raph and Donnie come running in from the dojo. And they too looked at me with shock. "Woah Calli!", Donnie said, stunned "It really did happen"

"You guys what is going on here?", I asked "I'm literally freaking out here!"

"You should look in that mirror and see for yourself", Raph said, pointing "Something happened to you Calli"

I pulled away from Mikey and I slowly walked over to the mirror in front of the door of the subway car. I gasped as I backed up a little seeing my reflection. I then slowly looked up seeing myself closer. I was no longer a human, instead I looked like a turtle like my family. I had light forest green skin just a little bit lighter than Leo's skin. I no longer had my dirty blonde curly hair and instead I was completely bald on top of my head. I turned and saw my brown slender shell that had a bit of blonde coloring to it, like parts of my hair color had been dyed into it. My arms and legs looked more muscular than they did when I was a human. My chest and belly was replaced with a yellow platted plastron, that curved out in my chest area, showing some figure. I looked down at my hands and feet seeing I had three fingers on each hand and only two toes on each foot. My face had extended out making a snoutI saw the necklace Leo gave me just a few hours ago still around my neck.

I then looked down at it holding it gently in my hand and I slowly looked back at my family, looking at me a little bit concerned. "You guys why I am turtle like you?", I asked

"Well Calli the substance that you were injected when you were attack by the Shredder, it was the mutagen that turned us into what we are", Donnie said "And since Leo touched you when you were injected you were changed into a turtle"

"Oh my goodness!", I said, shocked

"Are you okay?", Raph asked

"Well I really don't know what to say about this", I said "I'm just really...stunned"

"My sons who is this?", someone said

We then turned and saw Splinter come out of the dojo and he looked at me with surprise. "Master Splinter it's me, Callista", I said

"Callista?", Splinter said, shocked "But how?"

"Shredder attacked again", I said "He found out where Leo and I were on our date and he injected me with mutagen"

"My dear are you alright?", he asked, coming to me

"Well despite that I see myself as a mutant turtle and no longer a human, I'm alright", I said

"I'm sorry that this happened to you my dear one", he said, placing a paw on my shoulder

"It's alright Splinter, it's not your fault, it was just an unexpected event", I said

"Leo was so worried about you Calli", Mikey said "He never left your side, but he did end up doing so because it was just too much for him"

I gasped as I remembered Leo and how worried he must be about me. "Oh no Leo! Oh my gosh! He is probably worried sick about me!", I said "Where is he? Is he here?"

"He left just a few moments ago", Raph said "We think he ran off to Central Park across the street"

"Well he needs to know I'm alright!", I said

I started running over to the manhole cover, but Mikey caught me by the arm pulling me back towards him."Wait Calli, we have somethings for you first before you go out there", he said

"What do you mean?", I asked

"Wait here my dear", Splinter said "I'll be right back"

Splinter then disappeared into the dojo with the doors closing behind him. I looked at the doors curiously wondering what I was missing. I then heard footsteps inside in the dojo and then the doors opened up again and Splinter walked out carrying a few things in his paws. "What is that stuff?", I asked

Splinter smiled. "Your ninja gear", he said "Things that all ninjas and kunoichis need"

I smiled as he handed me my gear. I looked down and saw a brown belt with a sword holder, pink elbow and knee pads, and rolls of linen bandages. "Oh thank you Master Splinter", I said, looking up to him

He smiled and nodded and I sat down on the couch. I grabbed the linen bandages and I started wrapping them around my legs till they got just blow my knees and I then tied more on my arms till they got to my elbows. I strapped on my elbow and knee pads then I stood up and I strapped my belt around my waist and shell. I then took my katana beside the couch and I picked it up and spun it around in my hand and I put it in its hold behind my shell.

"I thank you for the gear", I said, smiling "But now I need to go find Leonardo"

I was about to walk off but then Splinter gripped my shoulder with his paw. "Callista", he said

I turned towards him. "You are missing one important thing", he said

I looked at him confused. "What?", I asked

He smiled softly and he pulled out something behind his back and held it both in his paws. I looked to see it was a pink bandanna with two eye holes cut in the fabric, that looked exactly like Leo's mask. "Your ninja mask", he said "The true symbol of a ninja"

"It's perfect", I said, softly

"You have earned the pink bandanna which symbolizes your love and kindness towards others and my son Leonardo", he said

I smiled up to him and I turned around and Splinter tied the bandanna around my head. I smoothed it out as Splinter tied my bandanna tails into a braid. He pushed my braid over my right shoulder. I turned and I smiled up to him. "How do I look?", I asked

"Very beautiful my dear", he said

"Thank you", I said, softly

"Woah you look awesome Calli!", Mikey said

"Yeah looking good!", Raph said

"I agree completely!", Donnie said, nodding his head

I giggled and blushed pink like my bandanna. "Thank you, you guys", I said, smiling softly "Now we should probably go find Leo, he should know that I'm alright and awake"

"You are right", Raph said "We better get going"

"Go to him Callista", Splinter said "He is waiting for you"

I smiled and I bowed respectfully to him. "Yes master", I said "Let's go boys!"

The boys and I climbed ran over towards the lair and we started to climb out of the lair and we ran out of the tunnel. We snuck over to Central Park quietly across the street and we quietly snuck around trying to spot Leo. And sure enough I expected finding him under the same oak tree where we met the day after we met in the alley while the boys hid behind the bushes just a few feet away from, while I hid behind a tree.. "Oh Leo", I said

Just as I was about to come out from my hiding spot, Raph grabbed my wrist pulling me back. "Wait here Calli", he said, quietly "We will get him ready for you and we will give you the signal when to come out"

"Alright then", I said, nodding my head quietly

I hid back behind the tree before Leo could of seen me and the boys came out quietly from the bushes and I watched from a distance them walking over towards him.

"Hey bro", Raph said

Leo looked up to him, but for only a few seconds then he looked back down to the ground. "Hey", he said, quietly

"You doing alright?", Donnie asked

Leo just shook his head slowly. "No", he said "I'm not, it's all my fault. Calli is probably never going to forgive me for what happened to her. I feel like I just ruined her life even more than it already has. I just wish she would wake up and tell her how so sorry I am to her"

"Well I think Calli might have a different view on the situation Leo", Donnie said

"What do you mean? How do you know?", Leo asked, confused "She probably will hate me now"

"Well why don't you ask her yourself now?", Mikey said

"Wait what?", he asked

"Come out sissy!", Mikey called out

Leo's Pov...
I turned in the direction my brothers were facing and someone came out behind the tree slowly. It was a slender mutant female turtle. I looked at her with shock that I have never seen one before in my life and how beautiful she really looked. Her pink bandanna, similar like my own in a braid, rested over her right shoulder. Her light forest shade of green skin blended perfectly against the trees in the background. She turned and faced me and I looked at her dark blue eyes that were the darkest I have ever seen and they were so beautiful and mesmerizing. Wait I have seen those dark blue eyes before and I gasped as I looked around her neck seeing a pink heart pendant necklace that was exactly the same as the one I gave to Calli. Could this really be her? My girlfriend?

I slowly stood up as I faced her and she looked at me with a smile. "Calli?", I asked, stunned

She giggled and smiled. "Hey Leo", she said

I looked at her stunned realizing that it was indeed Calli. "CALLI!", I called out, running to her

"LEO!", she called out

Calli smiled and she came running towards me laughing happily. We came closer and closer to each other, then Calli jumped into my arms and I hugged her to me tightly as she hugged me close. I fell to my knees with her in my arms still keeping her in the tight hug. "Oh Calli, you are okay", I said, softly into her neck "You are alright"

"It's okay Leo I'm here", she said, softly, nuzzling my cheek

I sighed with happiness and I let a few silent tears fall down my cheeks as I hugged her closer to me. "It's okay Leo, I'm okay", she said

She probably saw my tears and I felt her hand slowly wiped them away from my eyes and I looked at her as she looked at me with a smile. "Don't cry Leo", she said, softly "Everything is alright"

I smiled happily seeing my girlfriend again and I hugged her to me tightly and she giggled hugging me back. I heard the sounds of footsteps coming from behind and I looked back a little and saw out of the corner of my eye my brothers come walking up to the both of us. I slowly stood up bringing Calli up on her feet, still keeping her in the hug and I kissed her cheek softly.

Calli's Pov...
"Leo are you okay?", I asked, concerned "I was so worried about you, I didn't see you in the lair when I woke up. I worried that you might of been hurt from the fight with the Shredder"

He looked at little upset and I moved closer to him, placing my hand on his shoulder. "I'm really sorry Calli", Leo said, softly "I didn't mean for Shredder to attack you and he changed you into a turtle like me, it's all my fault. I just thought you would be angry at me for letting this happen, I just couldn't handle it all"

I gasped softly at what he said of how I would of react to him, like he thought."Leo I could never be angry at you", I said, hugging him softly "What happened wasn't your fault. You did protect me, it's because I'm still alive and breathing and I'm here with you now"

He only smiled just a little. "I just thought you wouldn't love me anymore that you were turned into something like me", he said

He looked down at the ground and I looked at him softly with concern. I put my hand under his chin and I brought his face back up to mine. "Leo what made you think that?", I said "Leo you know I still love you no matter what. To be honest I'm not upset for what happened to me, and it's not something, its someone. You are a somebody, not a thing. It will take me a little bit to get used to my new appearance, but that's okay. What matters though to me now is that you and I are still together and our love didn't change for what happened. Nothing changed between you and I, all except from my appearance, that's all"

Leo smiled more and I smiled seeing him smile. "I'm glad nothing changed", he said

"I am too", I said, softly "My Fearless Leader"

We both hugged each other tightly. "Awww young love", Mikey said, in a dreamy voice

I blushed red in Leo's shoulder and I heard Mikey yelp in pain. "Owwww", Mikey said

"Don't ruin the moment Mikey", Donnie said, a bit annoyed

I giggled and smiled, then I pulled away from a hug. "Come on you guys I think we should let them be", Donnie said

"See you later love birds", Mikey said, laughing

I blushed and giggled. But then I heard the sound of a slap and I looked and saw Raph had slapped Mikey behind the head. "Thanks Raph", Leo said

"Happy to help", Raph said

I giggled and smiled and I saw Mikey grunted annoyed as they walked out of the park back towards the lair, leaving me and Leo alone. "Well now that I'm awake and alright, shall we continue on with our date?", I asked

"Yes", he said, softly "Let's do that"

I smiled and he offered me his arm and I took it with a smile and Leo lead us out of the park and we walked down the street and we made it back to the valley of flowers. We walked through the many colorful flowers and we made it back to our date spot on the tall hill, that laid untouched since the fight with the Shredder. I sat down carefully back on the blanket and I put back the plate, the glasses, and bottle of sparkling water back in the picnic basket and I set the basket to the side of the hill and Leo pulled me to him as we had more room on the blanket.

The moon was now higher up into the sky right above us, glowing like a natural spotlight. I felt Leo's hand slowly slide on top of mine and I looked at Leo who smiled at me gently, but yet sweetly and I smiled up to him with admiration and love.

Leo and I stared into each other's eyes forgetting the world around us both, its like we were just too blinded with our love for each other to notice anything going on. I didn't notice that Leo had actually shifted closer to me where his chest was touching mine and I felt his arm wrap around my waist and his hand stroked my cheek. I snapped out of my daze and I giggled silently and blushed heavily pink, feeling very excited inside, but I was yet calm on the outside. Leo then started moving his head forward as mine moved towards his and both of our eyes started to close and then finally after so long, our lips finally touched softly into a kiss. I kept thinking that this was all a dream and I opened my eyes slightly only to see Leo was still kissing me. But it was not, this moment was real. I then slowly closed my eyes and I started kissing Leo back.

My hands climbed up his chest and they went to his shoulders and gripped them gently and his other arm wrapped around my waist with his other pulling me closer. The kiss was so passionate, sweet, but yet gentle just like Leo. It soon started to deepen as I wrapped my arms around Leo's neck and one of his arms around my waist then slowly climbed up my shell and his hand went behind my head deepening the kiss. I pulled Leo closer to me and Leo moved more on top of me and his weight began to push me back and I fell backwards pulling Leo with me, not breaking our kiss. Leo rubbed my sides and it sent shivers down my spine.

I then felt Leo's tongue lick my lower lip softly and I smiled and I slowly opened my mouth and Leo's tongue quickly entered inside. His soft tongue touched mine with care and affection and I moaned lowly in the kiss. I gripped Leo's shoulder giving it a squeeze as his tongue explored inside my mouth and as it caressed mine with love. I felt Leo rub my thigh with his soft warm hand and I shivered against him as his hand slowly went up and rubbed my hip in a circular motion.

I moaned a little bit louder and my hand slowly went up behind his head and I pulled his head closer to mine as Leo moved closer deepening the kiss. I felt Leo open his mouth and I licked his lip for access and he chuckled lowly in the kiss. I smiled as he granted me access and my tongue slowly made its way inside reuniting with his. Leo and I both moaned in the kiss, making our lips vibrate against each others and the gap between us both began to close as we hugged each there close as Leo laid down on top of me gently.

I felt Leo's lips slowly pull away from mine and we stared at each other hazily from our moment of romance. Leo's hand stroked my cheek softly and I sighed with bless at his loving touch, closing my eyes. I giggled as Leo pecked my cheek and I looked back up to him. "How was that?", he asked, softly

"Oh Leonardo", I said, hugging him "It was...beautiful"

Leo smiled and he leaned in again and kissed me passionately and I giggled and kissed back with love. "You do realize though the boys are going to make fun of us now that we are kissing now you know that right?", I asked, giggling

"It doesn't matter", he said "If it means to show my love for my girl, then so be it"

I giggled and I leaned up and I placed my lips on his for another deep and loving kiss. "So...what should do now?", I asked

"We should probably get back home it is getting rather late", he said

I looked up and saw the moon was glowing brightly and rose high up into the sky. "We probably should, but at least we finally got the chance to kiss", I said, looking up to him

"And it will be something I will never forget", he said, softly

I smiled and we both kissed each other once more enjoying the love the kiss had to offer to us both. We pulled away after a few moments and Leo slowly climbed off of me as his arms wrapped around me and he pulled me up to him. I smiled and giggled then Leo helped me to my feet. Leo gathered up the blanket in the basket and we then started to make our way back to the lair and we quietly climbed down inside the ladder seeing the lair completely dark. Leo offered me his hand as I climbed down quietly inside and we heard the sound of Mikey snoring from his bedroom.

"Looks like the coast is clear", Leo said, softly

"Yeah..for now", I said, giggling softly

Leo chuckled. "Wanna head back to my room?", he asked

"Sure, but we have to be quiet", I said "We don't want to wake them up"

Leo then started leading me quietly across the living room towards his bedroom. We quietly walked past the snoring sounds coming from Donnie's, Raph's and Mikey's bedrooms right down the wall and we finally made it to Leo's room. Leo quietly opened his creaking door and he stopped for when it was big enough that we could both squeeze inside. I slowly made my way inside with Leo following closely behind me and he slowly closed the door quietly. "That was a close one", he said

"Too close", I said, giggling "But we made it"

"Now I think we were in the middle of something", Leo said, with a smile "What was it? Oh right it was this"

Leo gripped my hips with his hands and he kissed my lips with passion. I giggled as I wrapped my arms around Leo's neck as I kissed him with passion. I felt Leo's arm wrap around my waist and his hand went behind my head deepening the kiss and he suddenly lifted me up in the air. I let out a quiet yelp of surprise as Leo laid me down on his bed, continuing our kiss. Leo rubbed my sides and I shivered as he caressed them with his fingers and they then traced me along my hips.

Leo then started to kiss my cheeks, then he kissed my chin and then I felt his soft lips slowly moving down under my chin and he started to kiss my neck. My eyes closed and let out a sigh of content feeling his lips on my skin. He kissed all over my neck not missing a single spot and I gasped softly as Leo found my sweet spot on my throat and he started kissing it deeply. I moaned softly as he then gave it a gentle lick and suck. I lifted my head up higher as Leo continued to lick at my sweet spot deeply.

I moved my hands up on Leo's shoulders and I suddenly flipped me over to where I was on top of him and he kept his smile, but looked at me quite surprised at my sudden move. I then kissed Leo's lips with love and his hands gripped my hips as I squeezed both of his shoulders with affection. I then moved my lips from Leo's and I kissed his cheeks softly and I then moved them down his neck, kissing it deeply. Leo then lifted his head up so I could have more room as I planted kisses all over. But it wasn't long till I heard Leo moan when I kissed just at the crook of his neck, thinking that I found his sweet spot. I smiled and I slowly began to lick and suck on it gently but deeply and Leo moaned with pleasure.

I then moved my lips back and reconnected them with Leo's, moving my hand behind his head to deepen the kiss. Leo wrapped his hand around mine as he rolled me over to where he was back on top of me again and we hugged each other tightly as we continued to kiss each other with deep passion and love. I felt Leo pull his lips back away from mine, but our lips seemed to have disagreed and they begged to be reunited with each other, but we then control the desire and we gave each other an affectionate nuzzle to the snout.

"Mmmm that was even better than the last", I said, softly

"They say each kiss gets better as your love grows", he said

I giggled and I gave him a gentle peck on the lips. I then let out a small yawn and my eyes slowly started fluttering close. "You sleepy?", he asked

"Oh no I'm not", I said, softly

But I let out another yawn and Leo chuckled and gave me a smirk. "Yes you are Calli", he said

I yawned again softly. "Okay I guess I am", I said, sleepily

"You should probably get some sleep", he said "It's been a big day for you"

"Mmmmmhmmmm", I said, nodding my head softly "It has been"

Leo smiled softly and he kissed my forehead softly stroking my cheek and my eyes slowly started to flutter close as I looked up at Leo tiredly as he looked back down at me with a loving smile. "Good night Leo", I said, quietly

I laid my head down on one of Leo's pillow and my eyes finally closed and I fell asleep. Leo pulled me up to where I was laying down on top of his body, curving perfectly against him. My head laid down on his shoulder and Leo's arms snaked around me and pulled me closer to him. I let out a quiet sigh of content and I felt Leo nuzzling his head against mine gently and I snuggled closer where my head buried into the crook of his neck. "Good night Calli", he said, softly

He gave my forehead a gentle kiss and he rested his head on top of mine and I smiled in my sleep, against my love. I smiled as Leo and I are now officially a couple and our love hasn't changed even though I have become a mutant turtle like my boyfriend. I thought about how my life has now changed more that I am now a teenage mutant turtle who does Ninjitsu with a mutant ninja family, and how I couldn't do things like I could do now now that I am different. But it didn't matter to me anymore. Life now was perfect for me. I have a loving and caring boyfriend, a new home, and a new family, that's all I wanted and needed. I started to fall deeper into sleep and I started to dream peacefully as I shifted in Leo's arms as Leo held me closer to him protectively.
