Disclaimer: Done this already. I don't earn any turtles, but apparently if I clean up my room, my dad will allow me to have one! I do own the three scientist dudes and the one hundred members of the public ;)

A/N: Thanks for all of the reviews. I really appreciate them. And don't worry, I have this story all planned out, and coincidentally I was going to have Raph marking his territory (to put it nicely) and doing other things, which will be seen in this chapter. As for the tranquils, yeah I know they are fast, but my excuse is that it's Bonesteel and he probably knows the exact dosage by now because he's a psycho.

As for chi proof glass, I wanted to achieve the concept of a communication barrier, and because Venus doesn't actually have any physical contact with anyone it only seemed natural that she can't tap into anybody's life force but her own. Also it'll be too weird. Honestly, if you were a guy, would you really want a chick reading your mind? With the scientists, they each will have their own ways of observation, which will be revealed later on. Anyway, on with the fic!

Chapter 3: Migration.

Leonardo still held a grudge on Raphael for the first day following the separation. But after having two cold and quiet nights without his energetic brother, Leo quickly began to regret the heated conversation they shared and wanted more than anything to speak and apologise to Raph. When the third day passed, there was still no sign that Raphael was going to be moving back in. The new room arrangements were permanent.

It had now been one whole week without speaking to Raphael, causing the atmosphere in Leo's cell to change dramatically. Things had been much quieter. The only sound in the prison was Mike's occasional incessant babbling which mainly revolved around the topics of pizza, video games, television and comic book heroes. Donatello still remained rather silent and withdrawn, though he did seem more relaxed without Raphael being stuck with him.

Leonardo had also become rather quiet, and had stopped practicing his martial arts for a while, because he feared that the scientists would isolate him too. This caused Leo to sit and think; something that he didn't have the time for back at the lair due to his numerous duties as leader. It didn't take him too long before his thoughts would drift to Venus. He knew he kind of liked her before this whole incident, but it was only after they were captured when he realised how much he actually did. The conversation that Mike had held earlier only pointed out the fact that he did love her even more.

Leo stared over towards Venus. She was practicing her Tai Chi again; trying to perfect her control of her inner energy through a series of movements. Venus had lived in total silence for two weeks, making the boys question her mental health. She had been coping rather well, though she had been caught talking to herself, which Donatello said was the first sign of insanity. Leo hated seeing Venus like this. He desperately wanted to talk to her, especially now with his new feelings he had.

Fast paced movements in Raphael's cell caught Leo's eye. The red-wearing turtle was angrily pacing around, arguing with himself. Unlike Venus, Raphael didn't take solitary confinement well. It was true that Raph enjoyed time alone, but deep down inside Raph needed his family for comfort. In a way, Raph never really left as they could still see him. But it was the conversational barrier that changed things, and it was that what aggravated Raphael the most. He needed Mike. He wanted the family atmosphere that he grew up in, no matter how much he despised it at times.

Being separated only made Raphael angrier than he already was. He was bored, and therefore became destructive. Throughout the past lonely week, Raphael had smashed the toilet twice, causing the others to question his behaviour. He used a sharp piece of porcelain from the destroyed toilet bowl to repeatedly scratch the glass, trying to create a weak point. Donatello had commented that this was a rather clever tactic on Raphael's part, although it did create complications as Raph's cell began to flood.

To solve the problem, the scientists carefully gassed Raph's prison and moved him to another one while they repaired the toilet. Raphael smashed the porcelain bowl the second time in his new cell, forcing the humans to anesthetise him for two days. He was then moved back into his first cell situated directly opposite Leo, Mike and Don's. From then on Raphael realised that his escape plan was hopeless, as he would be moved every time he attempted it. So for the rest of the week he resorted to more vulgar things for entertainment, such as pissing his name on the steel wall. Raphael had lost his mind.

What was interesting though was what was behind the steel doors. When Raphael was moved because of his destruction, the solitary entrance had to be opened, allowing the others to see what was out there. They were surprised to see grass of all things. This lead to the hypothesis that the doors lead directly outside and to their freedom.

Donatello shivered in his favourite corner as the temperature dropped. The lights would be turned out soon. Donatello wrapped his arms around himself, rubbing his shoulder area for warmth. He felt a lump in his arm, causing Don to curiously inspect it. The small protuberance was a rectangular shape, as though something had been imbedded below his right shoulder. Donatello looked over to his cell mates and was alarmed to see that they also had something in their upper arm.

"Leo? Something's been injected into our right arm," Donatello reported, pointing to his small rectangular lump. Leonardo's eyes immediately left Raph's cell and moved to inspect his own appendage. The turtle lightly touched his own bump with a finger.

"What is it?" Leo asked calmly while continuing to inspect it.

"Probably a microchip. A tracking device no doubt," Don suggested.

"Why? It's not as though we're going anywhere," Mike commented, joining in the conversation.

"But if we're given the opportunity we will. We're probably worth millions, so naturally the scientists don't want us to escape and disappear into the world," Leo explained, causing Don to nod in agreement. "Listen, if we do happen to get out of here, we need a plan on where we're going to go," Leo said seriously.

"Well, first of all we'll need to remove these tracking devices, otherwise we'll just be caught again. I have a piece of equipment in my lab back at the lair that can do the job," Donatello said. Leonardo shook his head.

"We can't go back there. Well, if we do, then we can't live there anymore. The scientists would just follow the tracking devices back to your lab. Besides, some of the Foot know of our address and our lair could have been discovered by now. I don't think it's safe to go back home…. Wait a second. Are you sure that the scientists can't hear our conversation, Donny?" Leo asked.

"If they could listen to what we're saying, then they would have given me pizza by now!" Mike said, answering Donatello's question for him.

"He's got a point," Don commented simply.

"Okay then," Leo said in acknowledgment before thinking quietly to himself. "I think we'll have to leave New York City. Bonesteel will be back on our tail if we escape, and it'll only be a matter of time for him to catch us again if we stay in the area," Leonardo analysed.

"That's if we're still in New York," Donatello commented dryly.

"What about April's farmhouse? We could go and live up there," Mike suggested hopefully.

"Good idea, but I don't know who owns the property now Mike. It could belong to the government, or some other people might have bought it. I don't know. But we can't go there. I think we have to leave the country as Los Angeles, Chicago and other major cities will be checked after New York is searched thoroughly," Leo said.

"Canada?" Mike suggested.

"Too cold. Our reflexes will be slowed down tremendously. It's bad enough living through the winter in New York!" Donatello commented.

"How about Mexico? That's warmer," Mike suggested again.

"That's a possibility. It's just going to be a bit hard if we ever wanted to get back into the United States," Leo said thoughtfully.

"Okay, so we're talking about overseas travel then. How about Japan? Splinter's told us enough about the country and customs for us to get by. We can also speak some of the language. Then there's China. Venus could take us to where she used to live," Donatello suggested.

"Too obvious. Bonesteel's heard Splinter's and Venus' accents and will no doubt hunt us down over there too," Leo said, rejecting Don's suggestion.

"Do you seriously think that Bonesteel will fly overseas to hunt us?" Mike questioned. Leonardo simply looked at him.

"Mike… It's Bonesteel," Leo said as his answer.

"…Yeah, you have a point," Mike sulked, before thinking up of another location. "What about the Amazon? No one would expect us to go there!"

Leonardo and Donatello rolled their eyes. "Mike, how do you propose we get there!?"

"What about Britain?" Mike suggested once again.

"Only problem with that is that we'll be landing at Heathrow. It's a very busy airport," Leo said sadly.

"France? Germany?" Donatello suggested.

"Language barrier," Leo answered simply. "We need a place that has a warm climate, that is easy to travel to, fairly civilised but not too popular that we're going to be seen, and a country that preferably speaks a language that we know," Leonardo summarised, trying to think of somewhere that fitted his description.

"What about Sydney, Australia?" Mike said hopefully. The other two turtles thought about this.

"That could work. It has a reasonably warm climate and it's an English speaking country. Australia, in land mass, is nearly the same size as the United States but it only has twenty million people. We could easily hide there. And it has all the luxuries of home. The only downside is that we'll have to stop over at LA airport first. But at least we're not expected to go over to Australia," Donatello said, supporting Mike's suggestion but also thinking of the pros and cons. Leonardo thought about this.

"Then it's down to either London or Sydney," Leo said, limiting the options.

"London's quicker to get to and Heathrow is less crowded than Los Angeles airport," Donatello said.

"But Sydney's less crowded than London, and it's a less obvious destination," Mike whined.

"What's it going to be?" Donatello questioned, looking at Leo for his final verdict. Leonardo crossed his arms and thought about the two options.

"Whatever leaves the airport first. If there's a plane that goes to LA before London, then we're going to Australia, and the same the other way around," Leo concluded.

"How are we going to tell Raph and Venus about this?" Mike asked.

"We'll rescue them and take them with us," Leo said with determination. Dr Yesmal entered the outside room. After having a quick look around, he turned out the lights, leaving the turtles in pitch blackness.
