Welcome back to another chapter of my story. I feel I must apologize for this chapter being a little long winded. I feel that this is not my absolute best, but then again I'm my own worst critic. Thank you again to all who reviewed last time and now came back for more. I appreciate it!

Chapter 3

The Replacement-'A Different Leo'

Raphael clenched his fists in anger; he couldn't believe it, Leo decides to come back home now?

Great, just great, they spent all that time grieving and searching for nothing. Nothing! And Leo dares to look at him with a confused look on his face, as if he didn't know what he done! Raph can feel that trademark anger boiling up inside him again, a feeling he thought was dead due to Leo's disappearance.

"What the hell are you doing here?" he roared, causing the other turtle to step back a little in shock.

"What?" the one named Leo asked, apparently taken aback by this one's yelling. Geez, he thought, what is his problem? The red masked turtle glared at him for a fraction of a second before going right up to his face. Too shocked to do anything, he allowed himself to be pushed back against one of their many pillars that held up this place while the other continued to yell in his face.

"You just decided to waltz back in here like nothing ever happened, when all this time we've been worried sick about you. We thought you were dead!"

"Re-Really?" the other turtle stuttered out. They were worried about me? Do they know me? He was surprised, cause certainly he did not know who they are. In fact, he didn't know who they were, unless this turtle, another mutant one just like him, liked to refer to himself in a plural form, which was a strange thing to do. But then everything about this place was strange. It looked like a home, because he can tell which part was the living room; he can see openings that looked like individual bedrooms, even one room with a Japanese-style doorway. Not to mention barely registering the fact that there was another one like him. He would've gotten a better hold on it, if that turtle in front of him would just stop shouting so much…

Raph meanwhile was dumfounded by his answer. He acted like no one was worried about him at all. How stupid can Leo get? Of course they were! He had no understanding as to why Leo was acting this way, like he doesn't know him, or his own family. Raphael was sure that Leo grew up with the rest of them. Maybe he got amnesia or somethin'? Yeah, that's it, he didn't need no Donny to diagnose for him, he got it all figured out. Still, Raph didn't back off of Leo's face, and he was getting pretty pissed. No one is allowed to get that close to him, without his permission…

"Get off of me!" Leo growled through clenched teeth as he pushed Raphael forcibly back. Raph stumbled a little on the steps, but quickly regained his balance while still keeping eye contact with the other turtle. Naturally, Donatello and Michelangelo decided at that moment to come out of the dojo to see what was going on. The noise coming from the entrance startled them and opened up their curiosity, as they heard another, strange voice speaking up. Don thought that he heard a bit of a southern accent from that voice, but he couldn't be sure as Raph's own voice overpowered the newer one with "What the hell is wrong with you?"

"What the hell do you mean?" the other turtle shouted back. He was slowly getting frustrated with this neanderthal of a mutant turtle. Why does he act like he knows him?

"Raph, dude, what are you…. Whoa…" Michelangelo's unfinished question hung in the air as he and Donatello looked at the newcomer with shock and a little bit of awe.

"Raphael, my son, what is going on?" Master Splinter said as he came out of his room upon hearing all the commotion outside it. But when he stepped into the main threshold of the lair, he saw four turtles standing there instead of three. The fourth turtle, he can see, was looking flustered at all the attention he got, it was obvious he didn't know what was going on. It was also obvious in the ninja sensei's eyes that he didn't belong here…

Raphael, meanwhile, practically jumped out of his shell when he heard Mike speak, then practically cricked his neck when he heard his sensei's door open, and he turned quickly in that direction. He can also feel, in the middle of his forehead, a major migraine coming on from trying to reason with this stupid turtle in front of him. He just wanted a nice, quiet, peaceful night with just his dark thoughts alone. It wasn't too much to ask for, right?

Apparently, he was wrong.

Leonardo, unknowingly, was echoing Raphael's thoughts. I just wanted a nice, quiet night; now I'm stuck in the SEWERS with these…these mutant creatures who just won't stop STARING at me like I came back from the dead. What the hell is going on here? I thought I was the only one that was ever mutated…

A moment passed while they all stared at each other, or rather, they stared at him as much as he was staring at them. It was all too confusing to take in. But finally, Master Splinter broke the awkward silence.

"Who are you?" the ninja master asked pointedly. Raphael stared at him in shock; doesn't his sensei recognize his own son? But before Raph opened his mouth, the other turtle answered first.

"My name is Leonardo." He said, tentatively, while the other three turtles whispered to each other for a second before Mike said, tearfully,

"Bro, where have you been? We missed you, I hope you know…" Donny nodded emphatically while Raph just stood there, his arms folded, a satisfied smirk across his face.

Leo's eyes practically bulged out of his head. He had brothers? Since when did that happen? Splinter spoke again before he could utter a word about his surprise.

"That is not your brother, my sons…" The three turtles looked at their sensei, jaws dropped. Not their brother?

"He is another mutant turtle, who just happened to have the same name. Please sit down with us, we have much to ask you." Splinter told him, leading the way to the area Raph was sitting at earlier. Raph, Mike, and Don all just looked at him for a moment before following him. Leonardo meanwhile, uttered a "Finally" in relief. He was saved just in time from, what could have been, a very mushy and awkward moment.

He was the last to come to the area as the three other turtles were already seated on the couch and the rat in one of the only two armchairs in the room. He took the other, but not before turning up his beak again at the nasty stains, exposed springs, and the very patched up cushion. He shook his head slightly at the way these creatures were living, before finally sitting down.

It did not pass unnoticed by Raphael though, as he watched the other turtle take his seat. He even took notice at how, after all the snobbish expressions he made at their armchair; he sat down in it like he owned it. His body position in the chair made him look like a confident king, and it was that, that made the hotheaded turtle's blood boil…

Splinter eyed the other turtle for a moment before resuming his questioning, "How did you manage to find this place?" Leonardo's easy smile made towards his master caused Raph's muscles tense up.

"Why, I just followed the voice here, that's all." He said in a soft drawl. The turtles exchanged looks with one another. Voices?

Splinter was unnerved, "Voices?" he asked the wayward turtle suspiciously. Maybe something happened in battle that made him lose his mind. Those cuts and bruises on his body did look nasty…

Leonardo let out a frustrated sigh; "I'm not going crazy or anything like that. There was this echo's coming from the pipes of the sewers. I couldn't make out anything of what it was saying though; I just followed it here. And it was one voice, mind you, one." He put the emphasis on the last word, trying to make it clear that he was perfectly sane. But the family exchanged looks once more before Splinter continued.

"And how did you manage to open the door?"

Leonardo snorted, "I didn't, you opened it for me."

"What!" Raphael jumped up, angry that he could accuse them of doing such a thing.

"Calm down, my son." Splinter told his son sternly, but patiently.

"No, I won't. He just accused us of just opening the door for him, Sensei! As if we would just leave our sewer entrance open for the whole entire world to come in to our home!"

Leonardo snorted again, "As if any reasonable person would want to be in a dump like this."

Raphael rounded on him, fire burning in his eyes, how dare he insult his family, his very home? Mikey looked livid while Don simply looked at Leonardo as if he never seen anything like him before. Splinter meanwhile stayed the way he was, not reacting, but not reliquinshing eye contact either.

"Who the hell do you think you are? What, you think you had it better than this? Than us? You probably lied to us, too, telling us you are Leonardo to make us think you're our brother when really you're some crazy spy sent to kill us." Now, what Raphael said was a little far-fetched, but it could also be true at the same time. It wouldn't be the first. But somehow, even after he said that, Leonardo's face did not budge one bit. He did sound furious, though, as he said "I am Leonardo, and I'm not crazy nor a spy. And I've got the driver's license, social security card, and credit cards to prove that."

The turtles looked at him stunned driver's license? Credit card? These are all things need to have a normal life, and they didn't have any. They couldn't, not if they wanted to be found and experimented on, yet this turtle, Leonardo, had all those…and maybe more.

"So, what that on your hand?" Mikey asked the unsuspecting newcomer, desperate to even the field since that last insult he made. So Mikey did what he does best: being obnoxious, and the covered hand provided some excellent material to be nosy about, he felt he had seen something like that before. Fortunately, he was successful as Leonardo snarled and barked out

"None of your business!"

"Oooh, did he touch a nerve there, Leo?" Raph asked happily, anything that made the other turtle uncomfortable was a plus in his book. Leonardo shot a death glare his way, barely able to speak through clenched teeth.

"Don't call me 'Leo.' I hate that name. I highly prefer 'Leonardo' 'Leon' or better yet for you low class types, you can call me 'Mr. Takada.' but never call me 'Leo''" He said regally, but Raphael just smiled again as he said

"Whatever, Leo. I'll call you what I like." Leonardo's eye twitched, then in one movement, he was out of the chair and halfway to the sewer entrance.

"I'm leaving. I don't have to take this kind of shit from creatures like you." He called out to those still watching from behind.

"Fine, leave, have a nice life." Raph responded to Leon's retreating back. Good riddance…

"Stay." Splinter called out. All the turtles stopped what they were doing to look at him.

"What?" Raphael asked, that just seemed to be the word of the night.

"I said stay. There is probably a chance that he doesn't have anywhere to sleep tonight." The turtles started to protest, but Splinter simply held up a paw.

"Enough, Leon is welcomed to stay if he pleases. Uninvited or not, he is still a guest and we always offer help to those who come our way."

Leon thought about this for a moment. It was this or the streets again tonight, and of course there was only one answer to what he should do.

"Fine, I'll stay here, for now."

"You are not taking the spare bedroom." Mikey interjected. It was an insult to his brother to have that asshole sleep in there.

"No." Splinter agreed "He will be taking the couch."

Leon sighed, "Whatever, look, since I'm staying, is there a bathroom I can use? Or do I have to go out in the sewers to do my business?" He said 'sewers' again like it was a dirty word or some thing. Don could only shake his head.

"No, we have one, I'll show you where it is." And with that Don left with Leon following after. Mikey went to his bedroom shortly after that, holding his throbbing head, which just left Raph and Splinter alone in the room. Raph had only on word in his mind again, this time it was a question he aimed at Master Splinter.

"Why?"

Splinter took a moment, before turning to him and saying "Because, my son, I believe I have seen him somewhere before…"
