Leo came to again on the plane taking him to another facility out of state. His vision had cleared enough, but when he tried to rub his head, he found his arms were pulled above his head and restrained. He tried to move his legs and they too, were tied down. He looked down and discovered that he was on a transport bed.

"Oh, where am I?" Leo said.

"I see you are awake. You are on a plane destined for my private facility."

Leo felt his heart sink into his stomach when he heard that. "Where are you taking me?"

"Nebraska."

"NO! Let me go!" Leo began to struggle.

"You won't get loose. I made sure those restraints were good and tight and last the trip." Johnson said.

Leo stopped. "What do you want with me?"

"A special project that will help fund my boss's work. I wouldn't even give Donatello the full details. You'll find out soon enough." The man said.

Leo looked down at his body and found that all of his gear had been taken off his body, save for his mask. He felt a little naked without it. He was completely vulnerable and being taken far away from his family.

Within a few hours, the plane landed and Leo was wheeled off and put into a transport truck. He tried to get loose again, but again failing.

A few miles later, Leo was given a sedative, which he tried to fight, but it did its job and made his vision go out on him again.

"Aren't you going to knock him out?" One of the assistants asked.

"I want him to see through blurry eyes for a while. I think I like him more like this." Johnson said. "Take him to the surgery room. I want to get started right away with collecting fresh DNA and to get the project started as quickly as possible."

"Yes, Sir."

….

Leonardo saw spotty lights pass over him as he was wheeled down the hall. He didn't remember leaving the transport van or seeing the building that they were in. He had no idea where he was. They then passed through some doors and the table stopped. He still saw the bright lights, but was too sedated to do anything other than close his eyes.

"Where…?" Leo asked, his voice sticky due to the sedative.

"Just relax." He heard as he felt a band being tied around his left arm. It had blocked the blood flow. There was someone prodding on his arm and then he felt a sting as a needle pierced through to his vein.

"Don't…" Leo said weakly.

"There, Sir. We have fresh DNA." Leo heard.

"Good. Now I will examine it and then the real work will begin."

"What about the turtle?"

"Take him to his special room for now and tie him down." Johnson ordered. "And keep him under sedation until further notice."

"Yes, Sir."

As Leonardo was wheeled out of the room, Johnson smiled at the vile of blood in his hand. He would compare it with Don's and see what it held as Leonardo hadn't been mutated. Then he would get to work on other things to get the project further under way.

….

Leo was taken to a cell that had a bed in it and shackles around it. His limbs were untied and he was lifted off the table and carried to the bed.

Leo could make it out a little bit. He felt he was being laid on a soft surface. Then he felt metal being placed on his hands and legs again. Then something soft was laid over him: a blanket. Then Leo felt a new sting in his right bicep.

"Time to go to sleep for now, Turtle." Leo heard.

"No…" Leo said weakly, but it didn't take long for the drug to make him drift off.

Johnson got to work analyzing Leo's blood and DNA flushed from it. There certainly was more of the right kind of things seen in Leonardo's blood that hadn't been seen in Donatello's. This turtle was the one.

Now, more certain types of DNA had to be collected to get this to work. He had access to all sorts of alien DNA here too and that would have to be part of it, but now, he also needed another certain part of Leonardo's DNA to get started and it was much more complicated to get. He would worry about the alien and normal DNA first.

….

Sometime later on, Johnson had all the DNA lines processed and ready, but it still needed the final part. A final component from the turtle.

…..

Leo had been sleeping for some time and was slowly beginning to come out of his sedation.

A loud opening of his door made his head hurt. "Waking up I see. Sorry, Turtle. You are not going to be allowed to be fully awake for some time. But you are going to give us some more valuable DNA."

Leo thought they meant more blood as he was given more sedation, but he wasn't entirely out. His vision remained blurry. Then he felt a sting in his one of his thighs, making his leg jerk in response. What did they want with him?

Leo was kept sedated but not completely out and some seed was collected from him. Now to find out if he was fertile.

...

As Johnson looked at Leo's seed under his microscope, he saw they were moving about vigorously on their own and none looked abnormal. This was good and it was now the final part to the project.

He collected 4 amounts of the DNA into 4 little vials and they were added to 4 eggs for full fertilization. Three of them had been DNA from Leo's brothers in the past.

When Johnson saw the egg cells starting to divide, he knew it was time to get them implanted into their host parent mixed with the alien DNA to help them along.

….

Johnson went to see the sedated turtle. He had four good sized vials in his hands ready for injection.

When he was let into Leonardo's room, he found he was still asleep. Good. This would make it a lot less painful and much more surprising to the turtle when he woke up.

An assistant was with him and pulled the blanket down, revealing the turtle's body. He pulled it down to just over Leo's legs. Then a machine was wheeled into the room. The bed was moved away from the wall and Leo's arms were moved above his head.

The machine was started up and the wand placed on Leo's lower belly, trying to find some good spots for the embryos.

A good spot was found on the right side first, and then two were injected in through the skin on Leo's right side, then the other two were injected on the left side.

"There, it's all set into motion now." Johnson said, feeling proud of himself.

"But, why so many, Agent Johnson?"

"Because if any fail, then at least maybe one or two will survive this pregnancy to term." Johnson said. "And Agent Bishop needs them. There are some DNA from all the turtles in them, and some final DNA from Leonardo. These will be special babies. It took a lot of DNA combinations and they should make it to term. At least two should anyway."

"Are you sure that they will survive? This is a male turtle and has no uterus."

"He doesn't need one. The combination with the alien DNA will take care of that. They'll stay in his lower belly and make their own wombs to nourish the embryos."

"How long do you think he'll carry then?"

"Six to nine months, give or take, and Bishop gave me up to two years to do this project." Johnson said. "It will work one way or the other. And the turtle is not to be harmed."

"Yes, Sir."

"And get him prepped for food intake while asleep. In case he has morning sickness, I don't want him knowing about this pregnancy until we get him past the most dangerous time. Get him past his thirteenth week first, then wake him up. Keep him sedated until then." Johnson ordered.

"Yes, Sir."

After Johnson left, more assistants came in and wheeled the ultrasound machine out, but had some tubes in their hands.

When they were done with Leo, he was hooked up to a few machines with tubes coming out of him. He had two tubes in his mouth, one for his stomach for feeding him, and the other to make sure he could breathe. He was going to be kept sedated for quite some time. And the third tube was for elimination purposes so he wouldn't make a mess. It was all worked out.

Leonardo would be well taken care of during the early part of his pregnancy.
