A/N: This is a continuation from my other story, "Mutant L." If you haven't already read it, I suggest you do. It gives the background for Mona Lisa. You don't need to read Mutant L to understand this story, but things might make more sense. I'll upload the first few chapters today, since I have them ready to go. As always, please drop a review. I'm itching to know what you think!

Everyone battles with their own inner demons and it's no exception for the Turtles and their allies. Trust, loyalty and love will all be tested as their enemies plot to destroy them from within.

Follow: the Fearful Leader as he attempts to conquer the qualms consuming his life; the Tumultuous Turtle who constantly fights these internal monsters and must choose his past or his future; the Wishful Thinker that distorts fantasy from reality and lives in an actuality he never wanted to create; the Unsung Hero who is constantly underestimated and has something to prove; the Undaunted Kunoichi as the events of past and present finally bring her to her breaking point; the Lone Operative who must face the fact she may have a hopeless future; and the Remorseful Father as his past comes back to haunt him and create a divide in his family.

Characters: The Fearful Leader (Leo), The Tumultuous Turtle (Raph), The Wishful Thinker (Donnie), The Unsung Hero (Mikey), The Undaunted Kunoichi (April), The Lone Operative (Mona) and The Remorseful Father (Splinter).

Also, I do not own TMNT. I just like playing with the characters.

The Tumultuous Turtle – I

It was impossible to see what was in front of him. There could be something lying in his path, waiting to trip him, and the sky-high pile of equipment he carried could go flying all over the place. This worried him because these were for Mona and her new "office." She somehow convinced him to carry everything from Donnie's lab into her room which, by the way, was clear across the lair. She warned him if he broke anything that he would pay for it, and Raph was not going to find out what she meant by that.

It took several trips to get everything moved and with every step he complained. Even worse, his brothers poked fun at him the entire time because he fell for the, you're-my-strong-boyfriend-and-I-can't-possibly-carry-all-of-this-by-myself, trap. They laugh now, but they would get a good punching when he was done with this.

"Would you mind staying and help me hook all this up?" Mona requested as Raph sat down the last mechanical box.

"Are you sure you want me to help? Shouldn't Donnie be in here instead?"

She walked behind him, wrapping her body around his and squeezed his muscular arm, "He'll help, but we can't position and move all of this by ourselves. I need a strong man for that."

Raph sighed, partly giving in to her wishes and partly because he had no energy to argue. Mona then poked her head out her door and called for Donnie to help.

"What exactly are you setting up here?" Raph asked, "Aside from an office?"

"Do you want the long or short version?" Mona came back at him.

Raph just crossed his arms and glared at her, wordlessly giving her his answer.

"I'm setting up a video surveillance system. I've been running a freelance investigation business and I'll need this equipment to keep track of surface activity. Plus, it'll help me find more about the Kraang and my brother."

Donnie stepped in with a grin on his face, ready to tackle the complexity of the project before them. It was nauseously obvious he was too excited for this.

"I really think this system will be helpful, not only to you but for us as well! I developed the perfect software to use too. It's capable of high speed tracking and uses biometrics to identify people and places," Donnie grinned.

Yup, Raph wanted to hurl right now.

"You're kidding?! Biometrics? This is like a dream come true!" Mona squealed with equal enthusiasm.

Raph forced a cough, implying he was there and that he did not plan to stand around and listen to them geek out all day.

"Just tell me where you want things," Raph finally groaned.

Mona laughed his misfortune off, "Just start stacking those towers in two, two by four clusters."

This was going to be a long, long day.

Later that evening, Raph finally got the time to sit down and relax just before patrol time. He was too tired to go out, but knew he had to regardless. If Mona and Donnie were not so indecisive about where they wanted the equipment set up, maybe Raph would not be so tuckered out. He could have sworn he moved everything around at least a dozen and a half times. Once Mona was satisfied, Raph made a quick escape before she could rope him in to do more heavy work.

After sitting for a few minutes, he decided to flip on the TV. He did not have anything in particular in mind to watch, so he left it on the channel it was on previously. To his pleasant surprise, Grody to the Max was starting.

Tonight on Grody to the Max, our team investigates strange sightings of a "mutant" in Central Park. Eye-witness accounts describe the monster as a "ninja turtle."

The word "mutant" caught Raph's attention but it was "ninja turtle" part that stunned him.

"There's no way it could be…" he said aloud to himself.

"Did she just say something about a ninja turtle in Central Park?" Leo commented, overhearing the TV announcer's claims.

"Afraid so," Raph replied.

"You don't think?" Leo started to question.

"It's Slash," Raph confidently confirmed. It had to be him. There was no one else aside from them that could fit that description.

"I guess we have an objective for tonight's patrol," Leo stated.

Raph pondered the idea of testing out Mona's new toy and posed the idea to the older brother. He agreed it was a smart plan and they left to go have a visit with Mona.
