I DO NOT OWN TMNT OR ANY OF IT'S CHARACTERS

The Interrogation

On the way back home, Leo called Donnie to prepare Master Splinter for the arrival of their guest. As much as Leo wanted to skip introductions and go straight to questioning, he knew that Marcus may need a moment to swallow four mutant turtles and one mutant rat. When they did finally make it back they found that the remainder of their family, along with Casey, April, and Lilly, had made themselves comfortable in the living room. Reluctantly Leo escorted Marcus to sit in front of his father.

"Welcome Mr. Winters" Splinter said as he peered down at him. "I know that our existence must come as a shock to you, I will be most happy to explain." It had been a long time since he has told the tale, and in his old age he found that he rather enjoyed telling it.

"Well as it turns out, I'm fully aware of your existence. Though I would love for you to explain your side of the story." All eyes were on Marcus as he sat and waited for Splinter to begin.

"Very well." Splinter said while he ran his old paw through his thinning beard. "Perhaps when I am finished you will be kind enough to explain how you are aware of us?" he asked carefully. "Of course." Marcus replied simply

Everyone settled in while Splinter explained how they were created and the involvement of April. Leo had heard this story a million times and kept his attention on Marcus. When his father began telling how they trained in Ninjutsu, he watched as Marcus smiled and shook his head in disbelief.

"It is truly remarkable, that you were able to teach yourself." Marcus commented. "I did not realize the mutagen was able to increase your brain power to such levels." Splinter merely smiled at his comment "Yes, it has made us quite intelligent."

"Well not all of us." Mikey interrupted, he then cupped one of his hands to his mouth and leaned towards Marcus. "Raph's a little slower then the rest of us." He whispered loudly.

"Speak for ya self bonehead" Raph quipped as he leaned over Lilly and thumped Mikey on the nose. "Ow! Take a joke bro." Mikey rubbed his nose as Raph leaned back on the couch. "Psh living with you is a joke" Raph muttered under his breath.

"Raphael! That is enough." He may be an old rat, but that didn't mean he had lost his hearing. "Hai Sensei" Raph grumbled a little embarrassed.

"Now Mr. Winters." Marcus put his hand up to stop him. "Please, call me Marcus, or Mark if you would like" Splinter nodded with a smile. "Very well. Marcus, how is it that you know of us?"

"My father has acquired all of the details regarding your mutation after what happened to Sacks 10 years ago" Marcus stated honestly. This news made the turtles very uncomfortable.

"How did he 'acquire' all of this information." Leo asked as he walked to stand behind his father.

"Well. The level of Security Eric had, forced the hand of the FBI. In replace of him they had my father, a fellow scientist, over see all of the research he had regarding all of his tests and test subjects." Marcus motioned around the room.

"So I'm guessing the foot want that research?" Leo asked stepping around his father to stand next Marcus. "That is why they took you and Vivian, isn't it?" He finished folding his arms against his chest.

"Actually they are after the mutagen, and more than likely they saw us together. I am truly sorry about that by the way." He gestured to Vivian. "We're safe now. That's what matters." She replied with smile.

"But we destroyed all of the mutagen Sacks had." Donnie half said to himself, while he leaned back in his chair. "Yes, but my father was able to recreate it." Marcus replied easily.

Donnie leaned forward in his chair slowly. "Why would you want to recreate mutagen?" He was asking what everyone else wanted to know. Leo uncrossed his arms, and stepped in front of him. He stared down at him and waited for him to reply.

Marcus put his hands up and stepped back "Please allow me to explain." He began

"After 9 years of trial and error my father was able to synthesize the mutagen. They tested this mutagen on skin tissue and brain cells. Now of course they had to use very small amounts so that they didn't create something they may not be able to handle"

"Like other mutants." Donnie interjected as he stood from his computer chair.

Marcus nodded "Yes, so after my father was able to synthesize the mutagen, he immediately looked for a cure. What he found is that it would take a large amount of mutagen to create the retro mutagen. Unfortunately the budget the FBI put in place wouldn't allow them the funds needed to synthesize enough mutagen to create more than one dose." He Finished

"So why don't cha pony up your own money?" Raph challenged "We have offered to pay for half of the costs to create more, but the FBI doesn't see the need to create it. We have no proof that other mutants exist." Marcus replied earnestly

"If there are no other mutants out there, than why try and create it?" April asked suspiciously. "I have reason to believe the Foot has created their own mutants." Marcus replied

"You just said you didn't have any proof." Leo stated crossing his arms again. "I don't have proof no, but unfortunately we may have a leak in our department. Someone is releasing the information to them. If they are able to synthesize the mutagen, nothing will stop them from using it." Marcus defended

At this Leo deflated and stepped aside for his father. "I'm afraid you are right Marcus, The Foot will take advantage of the opportunity." Splinter acknowledged

"What if you had enough of the pure mutagen? Could you make the retro mutagen with that?" Donnie stepped forward. His brothers regarded him for a moment, all thinking the same thing.

Marcus turned to him in reply "It's hard to say. From what I read Erik had two canisters of mutagen years ago, what happened to them I do not know. Now it takes about ten canisters of the synthesized mutagen to make the cure."

"Filling one canister between the three of us, nearly got us killed." Leo gestured as Donnie nodded in agreement "That's just what I was thinking." Mikey sighed wistfully with a "Me too" as Raph barely breathed out "yeah."

"But I've found a way to aid the mutation. It allows the subject to change back and forth from the mutation back to the original subject." Marcus added

"How were you able to transform the mutagen?" Donnie asked curiously. "It's called Lunae." Marcus started. Raph turned to Lilly as she readjusted her self on the couch uneasily.

"It works as a an organic solvent. We use this solvent to denature, or change, the mutagen so that we could essentially mutate it. What we found was that the solvent had altered the mutagen already. After testing the results we found the mutation acceptable, all of the subjects were able to change back and forth." Marcus ended.

"Do you think using this Lunae mutagen on a mutant would allow them to change back to their original form?" Donnie asked. It wasn't a cure but I would be better then nothing.

"Actually that is the reason why we have created it, although I haven't had a way to test it. You five are the only mutants I have met, and I certainly wouldn't test it on either of you." Marcus responded. "Why Not?" Mikey asked confused.

Donnie rubbed his eyes. "Because we were never human. If we changed back to our original form we would just turn back into turtles, and more than likely would lose our current mind set."

"Yes, and there for you wouldn't possess the knowledge to change back to your mutated form." Marcus confirmed. "Snap Don, I think he just called you stupid" Mikey smiled, which earned him an eye roll or two.

"Have you performed any human testing?" Leo asked tentatively, gaining Marcus' immediate attention. "No, we haven't had any human subjects, but if we get to that stage we would accept volunteers" He answered fully.

"Where do you get this Lunae?" Donnie cut in. Marcus let out a sigh and cleared his throat. "That is a bit harder to explain. We get the Lunae from Lycans"

"Whaaaat?! Like Werewolves?" Mikey asked excitedly.

Raph noticed again that Lilly was shifting her weight as if she was uncomfortable. He looked down at her, she simply smiled and pat his leg signaling that she was fine. Raph knew her better than anyone, and he knew that she tends to shift her weight a lot when she's nervous.

"Close but not really." Marcus answered. "Werewolves were held by the lunar phase, and were savage beasts while in their mutated form. Lycans are able to change back and forth when they please, along with that they are able to keep their human minds."

"Holy shell! Are werewolves real?" Mikey asked still hung up on the fact that they were actually talking about werewolves. "Dude, don't be an idiot." Raph said shaking his head.

"What? I'm just saying if these Lycan things are real, what else is?" He justified. "To my knowledge no, I don't think werewolves are real." Marcus answered honestly

"But they could be." Mikey bartered. Leo turned to face Mikey and shot him the 'time to shut up' look. "Jeez, I'm just curious" Mikey said as he sat back against the couch

"So how did you come across a Lycan?" Leo asked skeptically as he turned back to Marcus. "As it turns out one of my dear friends is a Lycan." Marcus answered proudly.

"So why isn't the Lunae mutagen ready for human testing?" Donnie interceded. At that point Casey, who has been merely listening finally saw his chance. "I'm sorry, maybe I'm just crazy, but why the hell would you want to go testing this stuff on humans?"

"Again, we would only test it on volunteers. But if we can prove it works, the FBI may be able to aid us in producing more for any mutants that are out there. " Marcus answered, in which Casey rolled his eyes and leaned back against the wall where he was before.

Marcus turned back to Donnie. "Now the mutagen is technically ready, but the result wouldn't give the desired effect." Vivian looked up at him from the arm chair she was sitting in "What do you mean? Does it work or not?"

"It does," He began "but you see Ben is only a half breed, and the Lunae mutagen in his blood isn't strong enough to hold the original form for more than an hour. I feel that if we can get the mutagen from a pure bred we could create a new mutagen that would allow the subject to keep the change and still be able to change back to the mutated form. If I can create the Lunae mutagen, I would be able to aid any mutants that are willing to accept it. It isn't a cure, but it would allow them to have a some what normal life."

"So you need a pure bred Lycan to create the Lunae mutagen." Vivian stated as she began taking down her hair. "Yes, Ben has been searching for one." Marcus added with a smile

Splinter held on to Leo's arm as his son helped him stand from his favorite chair. "What could we do to help you?" He asked as he steadied himself.

"As it turns out finding a pure bred is quite difficult. In the past Lycans were hunted down and killed. Most of the existing Lycans are mix breeds." Marcus said sadly as he scratched the back of his head.

"How do you know a pure bred even exists then?" Leo asked "Ben was able to pick up the scent of one in New York, that is what we were discussing tonight. He is trying to track it down before the Foot do." Marcus answered hopefully.

Raphael noticed again that Lilly was shifting her weight, but he wasn't the only one to take note. He saw that Leo had caught the movement as well. He half expected Leo to notice, nothing gets past him anymore.

"Lil, you ok?" Raph whispered down to her. She smiled up at him "I'm fine. I just need to use the restroom." With that she stood and left the room.

"How would the Foot find this pure bred? By what you said, it sounds like you need a Lycan to track it down." Leo said bringing the attention back to Marcus

"The foot have their own half breed, and from what Ben can tell he is quite vicious." Marcus advised. He recalled to himself what Ben had said about the Lycan.

The foot were trying to get the Lycan to change back to it's human form, so that he wouldn't be a danger to them. Ben stated that the Lycan had killed three soldiers before they were able to take control of him. The Lycan had ripped their throats out with his massive jaws.

"So what do we do?" Mikey asked "It would seem that our best option would be to wait for Mr. Winters friend to locate this pure bred Lycan." Splinter answered as he took hold of Leo's arm again. His son then carefully led him to his meditation room.

Splinter had also seen how uncomfortable Lilly was about discussing this topic. Lilly has always been a confidant woman. He will have to meditate on this, perhaps it is time to have a talk with her.

Soooooo...WHAT DO YOU THINK!? This Chapter took a lot of thought and I would love some feedback. :)
