Leo got a bad feeling as soon as he walked into Donnie's lab after dinner. He watched Sadie shoot Don a sympathetic glance before she quickly excused herself and left.

"No progress?" Leo asked.

"Actually, with Sadie's help I was able to come up with an improved teleporter. The technology we created is really impressive, she's –,"

"A genius. I know, Donnie. What's the bad news?"

Donnie's face, which was excited in a way that Leo recognized as the Sadie effect, suddenly dropped.

"Tell me, Donatello."

"I have to start from scratch and create a new machine, Leo."

Leo sat down on a stool. "Scratch?"

"I'm sorry, Leo. With the new teleporter, it would be fairly simple to send you back. But I've tried everything I could think of to reconfigure this original machine but nothing is working to find your dimension. This machine was created to find you and bring you here, not give me coordinates for your location. I have no idea where you're from. I have no idea where to transport you."

Leo stared at Donnie as his stomach sank. He knew that this young Donatello had no idea how many dimensions there were to search through, either. Leo didn't even know for sure. He only had an idea based off the stories Usagi had told him. But apparently Donnie thought he'd be able to just create a machine that would allow him to start searching for Leo's world. For Leo's home.

Leo's chest felt tight again. He needed air. He left the lab without saying another word to Donnie and headed to the tunnels.

It wasn't long before he heard footsteps behind him. He stopped suddenly and turned to find Raphael trying to catch up with him.

"Don had bad news?" Raph asked before Leo could ask him why he was following him.

"Raph, listen to me," Leo said, thinking of his own Raph and how very very far away he now seemed since it looked like he wasn't going home any time soon. "Even if I never get to leave here, I am not a replacement for your Leo. You promise me right now that you're going to find him."

Raph stared at Leo's fierce blue eyes and nodded his head. "I promise I'll find him."

Leo nodded as his eyes softened. "You won't even have to do anything else, Raphael. He's loved you forever. You just have to show up."

Raph stared at this Leo's face. Into this Leo's blue eyes and thought again about how much he wanted his Leo back.

Leo turned to go before stopping to face Raph again. "I'm going for a run. Alone." He could see that Raph wanted to protest. Raphaels everywhere apparently hated his solitary running. "You go back to the lair."

Raph did want to protest. It was freezing cold outside and more importantly, Leo was upset and it would've been safer if he had someone watching his back while he worked out what was going through his head. But he nodded anyway and watched as Leo turned again and took off in a sprint.

Leo stood in the dark on the rooftop edge of what should've been Hamato Engineering and stared down at the street below him. He'd been to his old basketball court earlier and couldn't decide if he was happy or not to see the ball sitting right where the other Leo would've left it. He didn't feel like playing, though, so he moved on and found himself heading in the direction of what should've been his home.

Despite the loud sounds from the street below, his ears picked up footsteps behind him and he listened closely until he placed the heavier footfalls as Raphael's. He frowned. He'd gone to the basketball court and then here because no one else in this world knew where these places were. So either Raph followed him, or –

"What are you doing up here, Fearless?"

He froze when he heard the perfect pitch in that deep voice. His breathing stopped. He slowly turned and found his Raphael standing behind him. He stared at the vibrant emerald skin and saw his mark right there on Raph's bulky bicep.

"So help me Hamato Raphael, you'd better really be standing here in front of me," he said, his voice so tight the words barely made it out.

Raph's green eyes shone in the darkness but Leo realized immediately that this time the shine was from unshed tears.

"How did you-,"

But he didn't get to finish as Raph swiftly pulled him forward by his shoulders and covered Leo's mouth with his own as a small gasp left Leo. Raph's hands moved to the back of his neck and Leo was sure there'd be bruises there when they were finished but he couldn't find it within himself to care at that moment. Raphael could hold on to him as tight as he wanted. He reached his own hands up and squeezed Raph's arms in return, relishing the feel of solid muscle. He pushed his tongue into Raph's mouth and twisted it around Raph's tongue.

Raph broke the kiss only so he could pull his face away and look again at Leo's face. His eyes moved down Leo's body and back up again. "Are ya hurt at all? Are ya ok?"

Leo answered by pressing his face into Raph's neck and wrapping his arms around Raph's shell as a shiver ran through him.

"What mess did you get yerself into this time?" Raph whispered.

Leo shook his head. "I didn't do it." He pressed his mouth to Raph's again, pulling him close enough that their plastrons scraped together. He moved his face back into Raph's neck and said, "You'd better really be here."

"I'm definitely here, Leo," Raph said as he kissed the side of his face. "I told you a long time ago that yer mine and I'm keepin ya."

Leo pulled his face out of the emerald neck and smiled at him before he kissed him again.

Raph tightened his arms around Leo. "Yer freezing. Even yer tongue is cold."

Leo laughed. He lifted his face again. "Akito and Machi?"

Raph nodded. "They're worried but they're safe, Leo. They're ok." He squeezed Leo again. "I'm taking you home."

"Wait," Leo said. "I can't just leave. I have to go back and say goodbye. I can't just leave them without saying goodbye."

Raph frowned at him. "Who do you want to say goodbye to? Yer turtle-nappers?"

Leo ran a hand down the side of Raph's face. He knew this sounded crazy but he'd made progress with these brothers and he wasn't about to ruin it by repeating the other Leo's mistake of disappearing without a word. "They're our brothers. Their Splinter is dead and their Leo left. And they needed me. I have to say goodbye."

"They sucked ya out of our kitchen because they wanted a Leo?"

Leo could see the anger growing in Raph's eyes and remembered the anger he'd felt when he'd first arrived as well.

"I needed you more," Raph growled. He didn't care if these were his brothers. He was finished sharing Leonardo.

"I know, Raphie. I needed you so much it hurt," Leo said, tightening his hold on Raphael. He leaned forward and kissed him again.

After a few moments Raph pulled away and sighed. "Fine, let's go. The sooner we do this the sooner I can get you home safe."

Raph clutched Leo's hand as they moved across rooftops and down into the sewers as Leo quickly filled him in on who had brought him there and why. He stopped them right outside the lair entrance and tried to let go of Raph's hand.

Raph glared at him. "I'm keeping my hands on you."

"Raph, this Leo left before he and Raphael got together. I ended up telling this Raph about you and me when he asked, but Mike and Don don't know anything about it."

Raph glared at him again.

"Give me five minutes to say goodbye. Then I may just order you to keep your hands on me the rest of my life."

Raph continued to glare at him but released his hand before they entered the lair.

Raph glanced around at the bright and fully furnished sewer home. "This is weird," he murmured over to Leo.

Mikey and Woody entered the main room from the kitchen with bowls of popcorn and Mikey stopped in his tracks to stare at them. "Donnie!" he called out.

Leo and Raph watched as Donnie poked his head out of the lab. His eyes widened when he spotted Leo and Raph by the door. He moved slowly out of his lab and Raph watched as Sadie soon poked her head out of the lab as well.

"You wanted me to tell you when Leo came back," Mikey said to Donnie. "He's back. And either Raph's bulked up in the last ten minutes since I last saw him or that's not our Raph with him."

"Is that your Raphael?" Donnie asked, coming slightly closer to them, a look of disbelief on his face. "From your world?" He realized he could've asked the red-clad turtle standing next to Leo directly, but this Raph was larger than their Raph and Donnie felt slightly intimidated by the angry look this Raph was sending his way.

"Yes," Leo said, watching as the other Raph appeared at the top of the stairs. "He's come to take me home. But I wanted to say goodbye to you all before we left."

Raph watched as an extremely young Mikey darted to Leo and wrapped his arms around his shell. He heard Mikey whisper, "Thank you, Leo," and knew that Leo had been right in returning to say goodbye to these other brothers. Of course, Leo usually was right, Raph thought to himself as Leo shot him an 'I told you so' look. He hoped that Leo could read the 'smug dork' look he shot back at him.

Leo wrapped his arms around Mikey's shell and hugged him back. "I'm sure your Leo will be home soon," he murmured back to Mikey. "Donnie and Raph will make sure of it."

Donnie stepped forward next and rubbed his hand across the back of his neck as he said, "I'm sorry, Leo. I know I let you down. But I can't thank you enough for the changes you made around here for us. We did need you."

Leo nodded to Donnie as he pried Mikey off his plastron.

"I would kick yer ass, Don, but leader turtle here says I can't," Raph said. "Plus, he didn't tell me you guys were babies."

"We're not babies, old man," Mikey said, smiling over at him.

Raph smiled as he watched Woody poke Mikey in the side.

"How did you get here? How did you find him?" Donnie asked, finally feeling brave enough to address this new Raphael.

Raph took a deep breath and released it as he thought over everything he and his own family had been through in the last two months and watched as Leo's fingers twitched in reflex, fighting the urge to reach out and touch him.

"Well, once we figured out that Leo wasn't in our dimension anymore," Raph said, sending a pointed glare at Donnie who ducked his eyes to the floor, "our Donnie and Sadie created a machine to search other dimensions for him. That was the easy part," Raph said. "The hard part was tracking down a power source strong enough to make it run." He turned his attention back to Leo who stood listening. "We may have had to make a quick run to Dimension X to steal some crystals."

"What?!" Leo said, straightening and crossing his arms.

Raph almost laughed when he saw the other two little brothers in the room take a tiny step back out of the corner of his eyes. He didn't let the laugh escape though. He knew Leo wasn't going to like this next part.

"Don't worry, we brought Mikey with us and Akito even managed to bring home some extra crystals using that tail of his."

"You brought Akito to Dimension X?!"

"Who's Akito?" Mikey asked.

Leo ignored him. "Raphael!"

"I didn't bring him," Raph said, throwing his hands up as he met Leo's fierce blue gaze. "He just refused to be left behind and jumped through the portal before it closed. He wanted to help."

"How about Machi? Did you let her go too?"

Mikey wanted to ask who Machi was as well but decided to stay out of the strange discussion these other big brothers were having.

"No, she stayed behind with her favorite aunt."

Mikey and Donnie exchanged confused glances.

The younger Raphael slowly moved down the stairs. Watching another version of himself having a secret, albeit loud, conversation with this Leo was one of the most fascinating things he'd ever seen. He knew he could see what his other brothers couldn't see – the fear in Leo's eyes and the reassurance that Raph's eyes were sending back.

When Leo appeared calmer and even uncrossed his arms, Raph turned back to Donnie and continued. "So we got the power source we needed and Don was able to turn on his machine and start the search. It took a few days of running it non-stop because apparently there are about a gazillion or so dimensions it had to scan, but it finally found this one. And the rabbit got us our very own transporter to send me here and bring us back."

"You guys have a rabbit?" Mikey asked excitedly.

"Unfortunately, yes," Raphael said, rolling his eyes. "Quit smirkin at me," he said to Leo.

"Well, I'm glad you're going home, Leo," Donnie said and Leo could see the relief on Donnie's face that he was no longer in charge of finding a way to make that happen.

Leo's eyes shifted and Raph followed his gaze. His own eyes narrowed in on a younger version of himself now standing at the bottom of the stairs.

He watched though as Leo didn't make a move towards the other Raphael. Instead he raised his eye ridges in a silent question and Raph watched as the other Raph stood up a little straighter and nodded in return.

Raph watched as Leo began to unbuckle the spare katana he was wearing to leave them behind and he took the opportunity to head over to the alternate version of himself. "You find yer Leo," he growled to him, keeping his voice low so the others couldn't hear. "You don't give up until you find him and you apologize and you bring him home."

He watched as the other Raph nodded solemnly back to him.

"Cause whatever yer picturing in yer head as far as how it could be if you two were together, trust me, it's a million times better. Yer gonna take care of each other." He turned to go join Leo before stopping and poking a finger into the plastron of his alternate self. "And ya have better have kept yer damn hands off of my Leo." He smiled at the smirk he received for an answer.

Raph nodded his head towards the exit and Leo nodded in return. Leo stopped just before leaving and turned back to the group.

"By the way, Karai is in Japan. Call her and get her back here. She needs this family too."

A/N: I love reunion chapters.

Exciting update: I recently commissioned the amazing Sakycchan to create some artwork for this very chapter, which I have been able to add to this story on the A03/archives site WITHIN this chapter. It has also been added to my Tumblr page (Reader115 username on both sites). I highly recommend you check out this incredible visual as Sakycchan not only draws Leo and Raph exactly how I picture then anyway, but even researched what their individual marks could look like.
