Author's Note: Naturally we all know that I have no ownership whatsoever of Harry Potter and his fellow wizarding mates, or of the Teenage Mutant Ninja Turtles. Original characters are mine.

This chapter is a more of flashback, with a hint of breaks where it is clearly a conversation between Splinter, Severus and Remus, trying to be as tasteful as possible in those section, for they are also trying to warn of what these people are like to the father rat, in case they were to have the misfortune of being in their clutches.

Warning might be triggering for some.

Thank you Trickster32 for your review, happy to know I peaked your interest.

Chapter Three

Changes

Opening his eyes, confusion set in very quickly, as he sat up to find that he had been lying on a cold concrete floor, surrounded by titanium three titanium steel walls, one having a heavy looking door built in it, and the last 'wall' was a floor to ceiling pane of glass. He could see people on the other side of the glass, walking around, talking to each other and even looking right at him.

He banged on the glass and called out, only to get no response. Or whatever attention he did get wasn't the sort he was after, these people were just talking and looking and taking notes, then walking to and from. As though his calls were merely part of what they had expected and chose to not elaborate.

A chill went over his body and that was when he realised that he was stark naked.

There was a loud click like sound and the heavy door rolled upward, but not completely, just enough for whoever to shove and slide a stretcher under. Upon the stretcher was an unconscious and just as equally naked man. Someone he had not expected to see since leaving his old school not too long ago.

For whatever moral he somehow conjured, he went over to this other man and decided to check his pulse, just to be sure that he was okay. A form of relief came when he felt the palpitations within the neck and wrist.

He then moved over to the other side of the cell. He didn't know when the other man was to wake up, nor did he know what was going to happen. Heck! He didn't even know how in Merlin's name he got here in the first place, or how they got his fellow cellmate, either. What was worse wasn't so much the imprisonment, but it was the fact that his memory was starting to become foggy on certain details.

He could have sworn he knew the man they just placed in with him... well, his name and their sharing classes or something together, but he wasn't so sure, like whatever details he thought he knew was obscure and distorted... he was feeling sleepy again...

###

He was now waking up to find his arms and ankles cuffed down to an examination table. The cold steel against his naked back. Positioned upright, so he could see everything around him. Opposite to him was the man that was in the same cell as he was... what was his name again?

This man had short light brown hair, compared to his black shoulder length hair, slightly more beefed than he was, but still slim. He couldn't help but notice the scars... curious on how he got them, he hoped he hadn't been abused by those who were meant to love and care for him...

"Hello," the man spoke to him in a weak tone. "You were in the same cell as me."

The man with the black hair nods. "I'm afraid I am unsure of what your name is. I would tell you mine, but -"

"You cannot remember as well?"

A shake of the head confirmed the light brown haired man's answer.

"Yet I feel as though we did know each other," he couldn't help saying to the man with black hair.

"And I, with you."

"I see that you've both been talking on and off, until you have each learned that whatever memories you may have once had have been erased," spoke a sinister sounding voice, laced with satisfaction.

In walked a thin man wearing a stunning white lab coat and rounded gold framed glasses on a thin face topped with medium brown hair that was partly greying with a hint of auburn.

"Allow me to introduce myself, I am Doctor Orson and I am here to help you with the changes you are going to be going through."

"What changes?" asked the man with light brown hair.

"Now what fun would that be if I was to explain it all in one go?" Doctor Orson replies, walking over to him. "Just know that all of this is for your own good, Roman."

"Roman?"

"Why, that is your name, don't you remember?"

'Roman' shook his head. "No, I do not."

"Well, you ought to remember it now, it's been your name for as long you've been with us," said Doctor Orson. "Whereas you," looking at the other man on the opposite to them, "as you should remember, are Severin."

Both men tried to recollect anything that would support this, but with nothing else, they supposed that these had to be their names.

"And... how long have we been here?" 'Severin' dares to ask.

"Long enough for some of the changes to take effect, but not all of them, as there is still much to do in order to be able to accomplish what we really need," said Dr Orson, his thin lipped smile not leaving his face, as he pulled a pair of rubber gloves out from his pocket and placed them on his hands. "First thing is first, now that you are both conscious, the real fun can truly begin."

When he said this the lighting brightened on up to reveal a very large area room, filled with so many items from the smallest of scalpels to a large very thick glassed tank.

"I am going to be collecting much required samples. Of course I am only but one person, so I will have my team of selected and very well trusted individuals to help me carry out not only the sample collecting, but the tests we will be having you go through."

When he said this, five people wearing white coats and masks over their noses and mouths came walking in, placing gloves upon their hands.

"For what purpose?"

"Ever the one to question everything, aren't you, Severin?"

"It would be nice to be informed."

Dr Orson wagged his finger; "Tut-tut, Roman, all you both need to know is that this is for your own good, what you will be put through will ensure that many afterwards will benefit." He then went to a sterile and prepped table, where many instruments lay in wait, beside the erect table Roman was cuffed to, and picked up a strap and placed it around the restrained man's arm and tied it off and managed to find a nice vein, placing a needle with blood collecting vial right into it and drawing a nice thick red of blood. "Excellent."

Two of the five had moved over to assist Dr Orson, while the other three moved over to start on Severin.

The taking of the blood samples wasn't that bad, but what they were about to endure was much more worse and much more violating. Especially when they saw the little collection container and hands started to grab in a region that caused them both to want to move away. Severin slammed his back into the table, trying to fight and protest; Roman just struggled and gritted his teeth.

"Wahoo this one's a fighter! That might prove to be useful," said one of the white coats, almost laughing.

"Please stop!" Severin cried out.

"Oh come on, every bloke loves nothing more than to get a decent hand job," said the white coat. "Relax will ya!"

Stray tears were escaping down the man's face, Roman could see the sheer anguish from his position. His heart thumped hard with the feel of sorry for Severin, knowing there was nothing he could do to help the situation, for he, too, was just as stuck.

They endured more poking and prodding, ending with the Dr Orson coming in with a series of vials, each one filled with substances that neither had a clue on what they were. Two of them contained green, almost glowing ooze looking stuff.

"We're going to play a little game," he tells the two men. "We are going to find out which one of you is going to gets which syringe with these different altering substances. It's very, very simple, all you have to do, is answer a few simple questions."

Both men looked at each other, then at Dr Orson, eyeing the vials with expressions of dread. Even more when the White Coat Assistants started to place needles attached to machines that was able to hold the vials

"First question I am going to ask is what your names are?"

Frowning at this, the men weren't sure if this was a trick question.

"Severin," said Severin.

"Remus Lupin," Roman then answered, as if his memory just jolted in. "You're Severus Snape!" Looking at the other restrained man still facing opposite to him.

Without speaking, Dr Orson picks up two of the vials, then places on in the holder that was next to 'Remus... Roman...?' While he put the other one in the machine beside Severin.

"Next question. If you could control any of the elements I am going to name, which would you choose? Water, Earth, Fire or Air? You are to choose two."

"Earth and Fire," said Remus, still confused on how he got here and why 'Severus' didn't know who he was.

"Water and Air," said Severin.

This allowed another vial each to be placed in.

With each question asked, this added a vial to whatever seemed to match whatever answers were given. Noting that they were marked and coded.

It wasn't long before each of the machines had ten vials each. No sooner at the last ones been put in place, did Dr Orson stand back with the rest of the crew and gave the orders to press the buttons that was to start compressing the substance slowly, one by one, into their victims.

Pain seared through them both, then a sudden wash of relief, only to be seeing stars once more. It wasn't clear whether he was hearing himself scream or the other guy, but when his vision cleared a little, he frowned at the sight of him...

"Remus Lupin?" he said, before being engulfed once more by the tremendous pain.

###

"The things we endured," Severus's voice sounded almost distant upon the memories of explaining; "How our daughters were forced to exist and knowing what would happen if we stayed and they were to be born there..." he shook his head.

It was now night time, the four Turtles were all placed into bed, with extra help from Remus and Severus, which Splinter truly appreciated. They even went as far as, asking before doing so, fixing the couches, beds and a few other items, so they looked almost brand new. Not a spring to be seen, or mould to cause sickness.

So when they knew it was safe from innocent ears, Splinter was told of the people from EWATGRI. They saw Splinter's ears twitch at the mention of this.

"You've heard of them?" Remus asked.

"They are the reason we, my Turtles and I, are how we are," said Splinter. "Only, I didn't know that there were three extra letters, believing they were just known as TGRI."

Splinter did allow these men to know how he and his sons came to be, given that they were giving him the privilege to know as much as they were allowing to give about them and their daughters.

"Guess we are not as different as it seems," said Severus, thoughtfully.

"How so?" Splinter asks. "I am not doubting what you are saying, I just wish to understand better."

Remus and Severus looked at each other for a moment. It wasn't so much a hesitation, more like an internal debate between the two. Until Severus started to unbutton his long sleeved shirt, standing up when he got halfway down and then pulling the material away and off.

Splinter placed a hand just on his bottom lip, more stunned than he thought he would be upon the sight of the same slit like gills on each of his sides, between the pelvic and bottom rib bones, patterned with smooth scale like skin around them, that seemed to blend in very well with his 'human' skin.

"That is only a small partial of the evidence on what we went through," Remus said, knowing just how hard Severus struggled with this, more than Remus did himself, (though Severus did know more of what Remus let on at times).

###

Huddled in a near foetal position on the hard floor of his cell, shaking profusely, Severus was trying to comprehend on what he had just gone through over the past week... had it been a week? He didn't know. Maybe it had been two weeks. Neither he, nor Remus, were allowed to know what the exact time of the day was, or even the date, the month... not even the year...

'Why would you wish to concern yourself over such a fickle matter that is time?' Dr Orson drawled when Remus had asked. 'Such beauties such as yourselves of the high superiority I have given you oughtn't to waste your minds upon it.'

Superiority, Severus thought with a near snort. He didn't feel superior right now; lying on the floor, still without clothing. He wasn't cold, oddly enough, the shaking was for other reasons, the pain his body had gone through, the tests and transformations... and the mind games.

Dr Orson insisting on calling them Severin and Roman. Torturing them if they dared to say otherwise.

Severus still couldn't get the visual of him witnessing Remus being forced onto his stomach, tied down by his wrists and ankles before dragging Severus over and...

He could still hear himself protesting as he was forced over the top of Remus and the cries, which was turned into unwanted panting, then into chaotic sounding snarls and growls that was mixed with erotic and scary.

Even more when they somehow found that their restraints were removed, allowing them to really have at each other...

A blanket being placed upon him took him out of the memory and into the present, seeing the man he was made to...

"We were given the privilege of blankets for a change," Remus said, sitting down, leaning against the wall, not too far from Severus, and wrapping his own blanket around himself.

Not moving from his spot, Severus tilted his head up and looked at Remus.

"You shouldn't be near me," his voice strained.

Remus was puzzled. "Why?"

"Because... because..." Severus struggled to find the words. "I'm dangerous!"

Taking a few moments to gather what he was meaning by it.

"We were both forced into that position, Severus..." Remus then concluded.

"But... I never thought... Hogwarts was one thing... but..."

Seeing the man he had once watched endure whatever brawls he got into from James Potter and Sirius Black – though he was able to hold his own on many of those occasions – starting to break down right in front of him, Remus didn't know what to do. Except the one thing he didn't know whether he would be rejected for it or not.

Remus moved closer to Severus, until he was behind him and carefully wrapped his arms around him, being careful to not get that close with particular body parts. Severus didn't expect him to accept this gesture, at first he wanted to push away, scream that he shouldn't be touched, that he was too dangerous for that... but the more he wanted to go against it, the more he knew that the comfort was what he just needed; unknowing to the both of them at that point that this small gesture was to become much more than they had expected it to turn out to be.

Every time they were placed back in their cell after whatever gruelling session they were made to go through; from Severus testing out how well he could actually breath under the water with his now fully grown in gills, to Remus controlling the ability to use fire, (within a controlled environment, because the White Coats weren't stupid enough to place themselves at risk of either one of these two turning on them while doing what needed to be done); they would just comfort each other, no longer caring who was watching, who the other man was, because none of that seemed to matter anymore... not when they were both in this same torturous hell, with no answers to the questions they keep asking every time.

'Why are we here?', 'How did we get here?', 'When are we going to get out of here?'; just to name a few.

The extra comfort for was whenever they were forced to act sexually... but after the third time this happened to them, it was no longer forced upon, because almost as soon as they were back in their cell after that episode, they were fast to wanting to finish whatever sexual tension that had been still built up within them. Severus allowing Remus to overpower him and... oh it felt good...

So, it became clear to from the White Coats perspective, and to the smug joy from Dr Orson upon this witnessing, they had achieved another goal they had hoped to tick off.

"Ladies and gentlemen, our first successful mating mutant pair thus far, two who once wouldn't have gotten along, according to our sources... now cannot take their hands off each other in a lust crazed passion," he said with gloating in his tone.

"But we've got other mating pairs, sir," said one of the White Coats, a little confused.

Dr Orson gave an understanding glance to his colleague; "I meant first successful male mating pair. This is some very good news indeed, one that must be shared to those who are helping us ensure this facility was even possible to begin with."

###

"So, in a sense you're almost forced to be partners to each other?" Splinter asks, carefully. He wasn't given the full nitty gritty details, but enough to put two and two together.

"At first it was forced, but now... not so much," said Remus.

"Our want to protect the other and whatever feelings that came with happened whilst in that place," Severus added.

"But how does this explain your daughters, if I am overstepping?"

"You are going to need to expand whatever you may have thought about reproductions and breeding habits," said Severus, shifting a little in his seat. His shirt was now back on, covering the fact that he had been mutated.

###

Remus placed a gentle hand on Severus's forehead.

"How are you feeling?"

"Like shit," Severus replied. "You?"

"Can't complain," said Remus, with a small smile. "I wasn't the one vomiting during the night. The smell nearly got me joining you, though."

Severus didn't know whether to shoot him a reproachful look or an amused one. "If you're not careful, I will make you join me!" he groaned; causing Remus to laugh, and immediately apologise for it.

The two had learned to find humour where they could, it was nice, from Remus's point of perspective, to know that when he got to really know Severus, he learned that he did have a genuine sense of humour underneath the tough, almost menacing, exterior he displayed. It was a mostly dry one, but it certainly made the situation lighter when it needed to.

Something that frustrated the heck out of Dr Orson and his White Coats, who weren't too fond of their experiments having any form joy, whatever it was, unless it was given to them in a form of privilege. But, it didn't stop the men from having a good crack at their expense, and when they were alone in their cell, holds no bars on what they wanted to say or do, as it was just themselves for company.

Again, still unknowing how much time had passed, more changes happened and more experiments. Now Severus had been violently ill for the last three days. He found relief whenever he was able to swim, but on dry land, during the night...

"I just want to curl under a rock and fucking die," Severus mumbled, head on Remus's blanketed lap – they were allowed to keep the blankets and pillows within their cells.

"May I join you?" Remus jested.

"To die, too?"

"Or just to curl up with you."

Remus was carefully running soft fingers across Severus's forehead and temples, which seemed to help get the man's mind off his queasy stomach.

"Try and get some rest," Remus said gently.

That would have been the ideal thing to do, if it hadn't been for the door to their cell to roll up and in walked the White Coats, armed with wands and tranquilisers as they always were, making it impossible for the two do anything that wasn't going to result in being zapped, knocked out or other.

"Get a move on!" one said.

Knowing by now that it wasn't within their best interest to disobey, the two men followed instruction from getting up to be walked out of their cell and led through a maze of hallways and doors – made to ensure that it was impossible for any chance of escape, until they reached the door that read in all capital MEDICAL EXAMINATION ROOM FOR MUTANTS. Inside looked every bit like a hospital examination room, with all the needed equipment and items that may be needed, from oxygen cylinders to rubber gloves.

"You," one white coat prodded to Remus, "Over there!"

Remus was pushed to get on to one of the two examination beds that was in here. They weren't like the tables they've been forced on, these were padded and quite comfortable. Except for the fact that he was being cuffed to ensure he didn't go anywhere. The same was done to Severus when he was made to get on the other bed.

"What are you going to do?" Severus asked.

"You didn't think we didn't notice you being unwell lately? As much as we want to put you through your paces, we do like to make sure that all is in working order and you are in shape," a white coat explains.

"Gee, how considerate," Severus bit back with sarcasm.

Ignoring his jab, the White Coat continued. "Well, we know that the changes to your physicality has finally become complete, or close to it. But with you, Severin, being ill for the past few days, we like to be better safe than sorry."

The examinations began with a blood sample extraction and eventually ending with an ultrasound.

They found Remus was in good order, nothing out of the ordinary... well... other than the obvious in the fact that the mutation of his genes and the werewolf contaminants he retrieved when he was a child had blended in beautifully, (according to what they notices and exchange of words were being put forward), where he was no longer in pain whenever he transformed into the beast form during the full moon; also making note on how within his mind he was... until he was in a situation where he needed to pass on his genetic code and with Severus being the one he was forced to pair up with and his 'instinct' for lack of better way of placing it, eventually taking over... and Severus allowing the act to happen, (so long as he got his way in return)...

It was a complete shock to the system to both men when they saw, right there on the screen, when they had moved on to Severus, not one, but four embryos, forming away within a makeshift womb inside of him.

"Looks like you're going to have your wish for wanting children Roman."

"How...?" Remus dared ask, for Severus was rendered speechless, not taking his eyes off of what was before him.

"Dr Orson placed a special formula into both of you during the mixing of the genes took place, to see who was likely to form a sustainable womb to allow for the possibility of breeding. Roman's didn't take hold, if anything his body literally rejected it, turning whatever testosterone or whatever his body needing against the chance of viable change that might have happened, which in turn was absorbed and expelling via different methods, making it look as though it was never there.

"Whereas for you, Severin... I knew you were a bit of a snivelling snot back in the day, but who knew that was because you were very much a girl!"

Severus jolted when he heard the word 'snivelling'.

"Who are you?"

"Don't worry, the Dark Lord is in belief that you're on some mission to find ways to help him live a life of immortality," the White Coat simply said. "While Dumbledore has his best people on the lookout for you... or so I have heard."

Severus wanted very much to charge at this person, at all of them wearing white.

"Dr Orson will be very pleased with this news. Sedated them and take them back to their cells."

The reason they are just called White Coats is because whenever Remus and Severus learned a name, any name, they were deliberately confused out to the point where they just didn't see the point in trying anymore. The only name that seemed to matter to these people was Dr Orson's.

There will be other chapters that will be with flashback scenes, to be advised.
