Excuse me for my weird writing style but this is the best way for me to tell the story in my opinion.
P.S. This is right after the episode "The Deadly Venom".
The four turtle brothers are fighting the Foot on top of the Shredders' building, after have been noticed that they have been strangely accurate lately around the turtles' neighborhood. So now, they are trying to fight the ninjas before Shredder arrives. But there are just coming more and more Foot ninjas.
R "Do these guys never quit?"
L "Come on, we have to keep fighting", he says while having four ninjas attacking him at once.
D "Easy for you to say! I have to fight and turn off the security mainline!"
L "Then turn that thing off, while we got the Foot ninjas!" he screams.
D "Okay, good idea." He runs to the machine in middle and kneels down to get to reach the keyboard. "Now let's see. If I just can get the access password, I can shut it down from the inside..".
M "Oooh, try with The Foot." he says happily.
D "Oh, come on, Mikey, that would be..." A "Pling!" is heard and Donnie points at Mikey without looking at him. "Don't. Even. Say it." Then he is back to work. "Alright, some types here and some there and.. Yes! The security mainline is off! Now they can't call for more backup!"
Sh "That won't be necessary anymore." He puts out his blades from his gauntlet and Tigerclaw, Xever, Rahzar, Rocksteady and Bebop shows up behind him.
L "Oboy.."
They fight for a little while. Mikey against Rahzar and Bebop, Raph against Xever and Rocksteady, Donnie against Tigerclaw, and Leo against Shredder and his ninjas. Leo is hit by a surprise attack from the Shredder and falls through one of Shredder's windows, where he gets surrounded by at least a dozen ninjas.
L "Aargh!"
R "Leo!"
The other turtles hurries to hit their opponents to get to Leo, but all of a sudden, the ninjas just fall apart.
L "Huh?"
R "What the heck is going on?"
They stand there as the ninjas fall one by one very quickly.
D "I don't know. They just collapses. As if there was an invisible ninja."
M "Can you make me one of those? Pretty please, please!" he grabs Donnies' arm and look at him with big eyes.
D "Yeah, Mikey, why not. As soon as I figure out how to do it!"
M * Hugs Donnie* "Ah, I love you bro. Soon, I will be invisible!"
Raph helps Leo up on his feet, and Leo can see something by the window.
R "Let's get out of here before Shreddhead is back." Then they return home.
At the lair. Donnie gives Leo an icebag, and he puts it on his left arm where he landed.
D "I wonder what that was all about."
R "Yeah. I bet it was just a bug in the system."
L "A girl."
Everyone is looking at him.
R "Come again?"
L "It was a girl who saved me."
D "Karai?"
L "No. She moved so fast I could barely see her. But she looked right at me, and her eye was clear blue."
D "Wait, did you just say one eye? As in singular?"
L "Yeah, the other one was covered with her black hair. But, you miss the point. The eye was clear blue, as in no pupil."
R "But that's impossible."
L "Well, I know what I saw." He glares at Raph, then he looks down on the floor. "What if we meet her again...?" It is quiet and no one knows what to say.
On the evening.
L "So, who's up for pizza?!"
All "Yeah!"
After Leo's back with pizza, they all eat with joy.
M "Mmmh. It's like heaven in my mouth."
D "Nothing's like an ordinary peperoni pizza."
R "You said it, bro."
Leo enjoys the meal, but is not really present. Later at night, he walks up on the roof after getting this weird feeling in his stomach. Not sickness after the pizza, but something else. He looks around a little everywhere.
L "Hey. You up here? I just want to talk to you."
First, there is no answer. He sighs and is just about to return home when he sees someone standing in the shadows.
L "Don't be afraid. You can step out of the shadows now." But she doesn't. "Who are you?"
Girl "You will find out very soon." It is a soft and light voice.
L "Why are you hiding in the shadows?" Then he reminds himself. "Oh, right. Ninja rule number one. Forgot about that, heheh.."
Girl *Titters*
He takes a step towards her, calmly to not frighten her.
L "Come on. May I see the one I'm speaking with?"
She hesitates for a moment. Then she steps out of the shadows, and out comes a beautiful girl, kind of as long as April, with light skin, and long flat hair, covering her right eye. The other eye is clear blue, no pupil. She is dressed in a short, lighter brink pink ninja coat, with black lines, and ninja tights and shoes. Leo is stunned by the girl.
L "Whoa. Your eye really is clear blue. But, why don't you have any pupil?"
Girl "Can I trust you?"
L "Ehm, well yeah, of course you can. Besides, you saved me. I owe you one. Thanks."
Girl "Good. Then meet me here the same time tomorrow night." And then she is gone.
L – But...
He returns to the lair, and tries not to waken the others.
R "And where, have you been exactly?"
Raph and Donnie stand with crossed arms behind Leo. He pretends like nothing and turns around.
L "Just on the roof."
D "Doing what, exactly?"
L "Nothing special. Just looking around.. a little bit."
R "Oh, really? Because somethin' tells me you weren't alone."
Leo freezes for a short moment and starts getting nervous, but keeps his cool.
L "What makes you say that?"
D "Well, suddenly a strange girl appears, saves your life, and now you want to train alone on the roof?"
Here is where he cannot lie anymore.
L *Sighs*. "Fine. I just wanted to know who she is."
R "You are so predictable." Leo glares at him.
D "So, did you find out who she is then?"
L "No. She wants to meet me tomorrow night again. I will try to get some more information. Where's Mikey by the way?
D "He's in the kitchen, trying to make some dinner." He point at the kitchen.
R "That's why we're out here. We don't dare to go inside."
In the kitchen.
M "This is gonna be the best dinner ever! Don't you agree my tasty friend?"
Ice Cream Kitty "Meaow."
M "That's what I thought." He hugs the mutated cat.
The next evening.
L "Hey, where are you?"
Girl "I'm here."
She stands at the same spot as the day before. He gives her a small, crooked smile.
L "So, heheh.. Wazzup?"
The girl looks at him with an unsecure face.
Girl "Uhm..?"
L "It means, how is it going? Or, what are you doing?"
Girl "Oh, of course." She blushes a little, barely visible but it is there. "Sorry, I am not so familiar with phrases."
L "That's okay. Maybe I can help you." He gets nervous again. "Ehm.. I mean, if you want me to."
Girl "That would be very nice of you. But I wanted to speak to you about something."
L "Like what?"
Girl "Everything."
At the lair. Leo runs into the lair where the guys are watching television.
L "Guys, you are not gonna believe what I've just found out!"
D "About the girl?"
They stand in front of him and he needs to catch his breath.
L "She's been living outside our lair almost her entire life!"
All "Say what?!"
R "She's been spying on us?!
L "Well, kind of. She's been watching us train and later trained herself."
M "But why would she do that?"
S "That, we have to find out."
Splinter comes out of his dorm, still injured and is getting help from his stick. But it he can somewhat go normally. Leo did not think of Splinter hearing them.
L "Master Splinter, I..."
S "It is okay, Leonardo. Though I am not sure if she is telling the truth."
L "I believe her."
Donnie crosses his arms and glares at Leo.
D "Oh, you mean like you believed Karai in the beginning?"
L "It's not the same thing."
R "Really..?"
L "Yes! And I think we should invite her here."
The three turtles gasps and recoil.
R "Are you nuts?!
D "Leo, you will risk blowing our cover."
M "Even I get that, Leo."
D "See?"
But Leo does not give up.
L "Well, can you at least meet her? We can meet her on the roof tomorrow night."
S "Very well. I will accompany you to see if she is telling the truth."
On the roof.
L "Hey, come here, my brothers want to meet you!"
They see her standing in the shadows. Raph takes a step towards her, but Leo stops him.
Y "And... your sensei?"
L "Yes. Please. They won't hurt you, I promise."
She slowly steps out of the shadows, and the turtles cannot believe what they are seeing.
R "Whoa."
D "Unbelievable."
M "Awesome."
D "Your eye really is clear blue. Fascinating. I'm Donatello by the way. It's nice to meet you."
R "I'm Raphael, and this bonehead is Michelangelo."
Y "Hi, it's very nice to meet you too."
R "So is everything Leo said true? About you hiding outside our lair and all that?"
Y *Nods*
Splinter has been a little after the others because of his injuries. He shows up behind them, and when he sees the eye of the girl, he is speechless for a couple of seconds.
S "No. It cannot be. Yumi?"
Y "Hi. Father."
