A/N: Just one more chapter left! Here's some bonus notes:

- P.S.D.D. is pronounced like "sid" (the "p" is silent like the "p" in "psychology")

- 12!Mikey calls Junior "JJ", which stands for "Jones Junior"

REUNION

Rat Jitsu led them up the stairs to the control box. He held the door open for them. April and Casey stood back as the brothers rushed in. Mikey was sitting in a spinny chair next to Donatello, both wearing sweatshirts and talking. Mikey spun around to turn towards them and smiled, "Guys!"

The brothers jumped on him, pulling him into a group hug. April could hear wet laughter and quiet questions coming from the group. She tried to distract herself and give them privacy by coming further into the room and looking around.

The room was a long thin rectangle. Three of the walls were windows, overlooking the arena. There was electronics along all the walls. The back wall had several screens, three were different angles of the now empty arena and another two seemed to be playing recap footage of Other-April sledding down the stadium stairs on a chair backing in her pajamas while Other-Raph looked on terrified.

The video footage changed to their fight with Donatello with the word 'DISQUALIFIED' in big red letters at the bottom. Speaking of Donatello, Donnie had just noticed his presence in the room and was yelling at him to stay away from Mikey. Donatello had an amused look on his face.

"Woah! Woah, Donnie its fine! Everything's cool!"

"Cool?! He kidnapped you!"

"No he didn't! What are you talking about?"

"Ah-" Donatello spoke up, "Leo might've implied in his email that you were being held against your will. And I kinda, sorta, didn't make him correct it."

Rat Jitsu gave Donatello a gentle slap upside the head, "Purple!"

"It was late! I hadn't slept in three days and Leo was being so annoying. I just wanted him to leave me alone so I could go to bed."

"So, Mikey is not a hostage?" Casey asked.

"No!"

"Good," Leo said, "because we're taking you home."

"Uhh, about that… I um, have some things to tell you."

Mikey looked nervous. He glanced over to Donatello who gave him a thumbs up. The brothers looked very confused. Rat Jitsu patted Donatello's shoulder, "Come now, I believe Orange Two wants to handle this on his own."

Rat Jitsu turned and headed for the door. April sensed this was going to be a family only thing and followed, noting that Casey had fell into step behind her. She paused as she passed Mikey to give him a quick hug, before stepping out of the room into the brightly lit hallway.

"What do you mean you're staying here? We're taking you home. That's why we're here."

"No. I mean, I'm staying here. I've chosen to stay here."

Mikey was getting frustrated. His brothers were just getting more and more confused. Donnie looked at Mikey, truly looked at him. He looked different, and not just because he was wearing clothes and has friendship bracelets up both wrists with painted nails. He looked like he felt lighter, like there was nothing dragging him down anymore. The two smiles Donnie has seen from him tonight felt more relaxed, more real than any of the recent ones he'd given back at home.

"You don't want to come home," Donnie realized.

Mikey nodded.

Leo looked heartbroken. Raph still looked confused. Raph squatted down and gently gripped Mikey's upper arms, "What do you mean you don't want to go home?"

Mikey took a big breath and sat up straighter, "I'm happy here Raph. I'm not happy back home. Here I can go out in public and order a pizza in person, here I have friends, here I'm learning magic. There's people who understand me here, who love me and want me to stay."

"And there's people back home who love you and want you to come home!" Raph quietly said.

"Raph," Mikey placed his hands on Raph's forearms, "I am home. This is my home now, where I belong."

"No, no, no Mikey. Home is with us. This is another dimension, we belong in the dimension we were born in."

"Actually we were ha-"

"Donnie!"

Leo took a small step and placed a hand on Raph's shoulder. "Mikey, are you sure about this?"

"Yes. I thought about it a lot. Don's working on an easier communication and transportation pathway between our universes, so I'll be able to text and visit you guys pretty much whenever I want. And of course we'll be together for holidays! Not to mention all the things I promised to show the guys when I give them a tour of our New York!"

Mikey's smile had returned. Donnie placed a hand on Mikey's head and Mikey turned to look at Donnie. Donnie felt pride for his little brother well up in his chest, and he teared up, "You're growing up, aren't you?"

Mikey nodded, "It's time for the next chapter of my life, and that's here in this world."

"Okay," Leo had tears in his eyes as well, "but I want text updates everyday. And you have to visit home one day a week. And-"

Mikey groaned. Donnie smiled.

"Leo you can't be serious! Does he even have a place to stay?"

Raph's had slipped down Mikey's arms to the point they were gripping each other by the wrists. Raph's face was full of pain.

"I'm staying with our counterparts. They've been taking care of me this whole time. Other-Mikey has even decided we're twins now, and me and JJ have been pulling shifts on Big Mama's non-illegal businesses. Right now Leon is trying to get us full time jobs at Run of the Mill."

"But they wouldn't let us speak to you-"

"No Raph. Leon does things in really roundabout ways, which looking back this whole tournament thing was probably not the best idea, but it was his way of intimidating you or showing you how well they can protect me? I'm a little confused on that part, but the gist of it was if the five of you had trouble trying to beat them one-on-one, then how are you going to do it when they all fight as a team?"

Donnie had to admit, that was a pretty solid argument. Their toughest battles tonight were won on technicalities. Other-Donnie was disqualified, Other-Leo was 'medically tapped', Short-Splinter out right threw his fight.

Raph was still searching for an argument. Mikey leaned down and hugged Raph.

"I'm safe here Raph. I have family here to keep me save."

Raph gripped Mikey back tightly, "I want you to text everyday, and I want to visit home three days a week and-"

Donnie and Leo joined the hug, and they stayed like that for a while. The sun had come up by the time they broke apart.

The brothers entered the main Party Room. Other-Donnie was asleep on a beanbag, a purple robot resting on his chest and tucked under his chin. Other-April and Other-Mikey had set up a karaoke machine and were singing A Whole New World, with a large fish mutant, a humanoid green slime person, and Primetime cheering them on, all of them now in pajamas. Big Raph was sitting in an old rusty beach chair eating cake next to his father, who was also trying to eat Raph's cake despite having his own slice. There were two gargoyle looking creatures flying around the snack table. Casey was conversing with Cassandra, and next to them on a couch was CJ fast asleep. Baron Draxum was showing April something that looked mystic. Mayhem the alien looking cat was curled up in a lawn chair. There were TV screens everywhere showing various clips from throughout the night.

Mikey smiled in such a genuine way as his eyes sweeped the room, "Aw, sweet! I want a shot at karaoke!"

"I'm next! You can sing with me!" Primetime called over.

Mikey led the way through the mishmashed room, stepping over discarded wrappers and blankets and pushing the various types of chairs out of his path. Mikey paused as they passed Draxum, reaching out and hugging him from behind, "Hey Other-Other-Dad, I want to introduce you to my other brothers."

Draxum turned to the side, placing an arm around Mikey and patting the top of his head, "Technically we've already met, but go ahead Orange Number Two."

"This is Leo, Raph, and Donnie!" Mikey pointed at them as he spoke, "Over there is Casey, and right here is April!"

Draxum gave a small laugh, "I know, I was just talking to her."

"And guys, this is Baron Draxum. He's other-us' other dad. The other-us get two dads! How cool is that!"

"Speaking of parents," Donnie piped in, "how old are 'other-us'? Cassandra looks to be the same age as her son, and Alternate-Me doesn't look old enough to have two kids."

"Ohhh," Mikey said, "yeah, that's a long story. We don't have time to go into it tonight."

"Actually," Baron Draxum leaned down and whispered to the four of them, "we are playing a 'practical joke' on the third Casey. Cassandra told him Blue is Junior's biological father, so just play along if he asks."

Mikey covered his mouth with his hands, trying to stifle his laughter, "Oh this is gonna be so funny. How'd he react?"

"He said 'no way' so Cassandra showed him a picture of Lou back when he was human and convinced him all the turtle genetics skipped a generation."

Everyone let out a laugh at that.

"How'd she do that?"

"She said some very confusing things about chromosomes and eggs, which as a geneticist myself I can assure you are incorrect."

"Oh this is too good," Raph said, "I'm so going to give him a fake shovel talk."

"Please let me be there for that," April said.

Mikey started giggling again, "Has he met S.H.E.L.L.D.O.N. yet? Should we tell him Casey One is his mom too?"

"Unfortunately he has. Purple showed him pictures of P.S.D.D. as well."

"Bummer."

"TALL MIKEY!" Primetime shouted from across the room, "We're up!"

"Leo, dude, don't freak out."

Casey had come up to Leo as he was perusing the snack table. There weren't many options left, most bowls and plates only held crumbs.

"Okay… What's up?"

Casey's face was red, and he was staring over Leo's shoulder. Leo looked behind him only to see the wall.

"So you know how CJ is like Other-Me's kid?"

Oh, Leo thought. Play along.

"Uh-huh."

"Well, he's uh, actually your kid too?"

"Oh yeah, I heard Other-Me call him 'sensei' earlier. He must be his student."

Casey groaned in annoyance, "No. You know how you call your dad 'Sensei'?"

"Yeah…" Leo pretended to be confused, "because I'm his student."

"Agh! No! I mean we-" Casey used finger quotes, "'make a baby' together, and that baby is CJ."

Leo grabbed a chip off his plate and took a bite, "You sure? I think you heard her wrong."

"No, no," Casey put a hand on each of Leo's shoulders, "I thought I did too, but she was very detailed in her explanation."

It was taking all of Leo's will power not to bust out laughing at Casey's devastated face right now. Leo has had a long, somewhat disappointing night. He decided to mess with Casey some more.

Leo let out a big sigh, "We'll, there's only one to do. We have to get married."

Casey choked on air. Leo put his plate down, grabbed a soda, popped the tab for him and handed it to a still coughing Casey, who he then forced into a chair.

Leo had to time this next part perfectly, "So first you'll have to ask Raph for permission. He's not going to be happy about his best friend marrying his brother. But given the circumstances, I'm sure he'll understand. He'll probably even encourage it, he's not a big fan of people having children out of wedlock."

Casey did a truly marvelous spit take.

While Casey was still recovering, Leo put a finger on his chin and sent a wink towards Raph, who had looked over to see what the commotion was about. Raph looked between Leo and Casey before getting the hint.

"Hmm… What do you think of a spring wedding?"

Casey buried his face in his hands, "First Donnie and now this! Raph is gonna tear me to shreds."

What happened with Donnie? Leo thought. He quickly nudged Casey's knee with his own, pointing over at Raph.

"Well, there he is." Leo began walking in the other direction, "Good luck!"

Casey sputtered, "Don't leave me here! Leo!"

The Aprils were off giggling in a corner, Cassandra had just left to take CJ and S.H.E.L.L.D.O.N. home, Draxum and the fish-lady had left before them. Donnie was currently watching the Raph vs Raph Dance Dance Revolution battle, but had lost interest when Sunita came over.

"So you're not a mutant?"

"Yep. I'm a yokai. I was born like this and so was my father, and so was my grandma, and so on."

Donnie took notice of the way she moved her arms around as she talked, how her body moved like animated water.

"Fascinating."

There was a groan and cheer that occurred simultaneously. Big Raph had failed to beat Raph. Raph was punching the air in victory.

Mikey walked Casey over to Other-Mikey and Other-Donnie. Casey was dragging his feet, he had been trying to avoid Donatello since he woke up. April watched as Mikey brought them all over to the couch they were lounging on.

Other-Mikey was talking animatedly, April noticed he and her Mikey had matching nail polish. He threw an arm around Casey and pulled them both down on the couch. Casey was now sandwiched, and a tad bit flustered, between him and Other-April.

April was having a blast talking to her other self. It had been a while since she'd had a girl friend to hang out with, let alone be able to talk to about the ninja turtle half of her life. April found the differences in their lives unbelievably interesting. How could two people, who were supposably the same person, have such different lives?

Donatello handed them both plates, "This one's for Green, and this one's for Yellow."

"Thanks Donnie!"

"Thank you," April tried not to blush as she took her plate. Other-April, or 'Green' as she had been dubbed by Mikey earlier in the night for her green hair wrap and pajama bottoms and April herself had been named 'Yellow' after her headband and shirt, had told her that despite Donatello's chilly personality he was actually a sweetheart. She could see that now, and it was undeniably attractive. She was going to have to take up Casey's avoidance technique if she wanted to survive the night without embarrassing herself.

Donatello sat down on one of the few real chairs in the room across from them, and Green kicked up her feet to rest them on his lap. Mikey sat on the cushioned arm and leaned towards Donatello. April felt Green shift a bit beside her, moving more towards Casey to make elbow room for her fork hand. Donatello nodded over to Casey, "You alright? You look like you're starting to overheat again."

April leaned forward to see Casey Jones blushing.

Was this what happened when he reappeared all flushed? April thought perhaps it was an effect of the portal. April remembered how he had been medically tapped for 'overheating'. Oh.

A quick look at Mikey, who made a shush gesture while winking, confirmed it.

April tried to repress her smile. So, Casey Jones could dish it out but he couldn't take it. Good to know.

"April," Donatello spoke to Green, "give him some room. Your weird mammalian heat is suffocating him."

Green mumbled and shifted away from Casey, "'Weird mammalian heat' let's see how you like it once the temperature drops down below fifty and I refuse to share a blanket with you during movie night."

Donatello gasped. "You wouldn't. You're not that cruel," Donatello sounded unsure.

Green gave him a smile that sent chills down April's spine, "We'll see about that, won't we?"

"No!" Other-Mikey cried, "You won't leave me to suffer too, will you?"

He gave Green the biggest puppy eyes, and she folded, "Of course not baby, you and Raph still have full winter cuddling privileges."

"Yes!"

"Wait what about Leo?"

"What about me?"

Primetime appeared behind Donatello. Green shot a glare at him, "He knows what he did."

Raph walked passed the group on the couch on his way out. Him and Other-Raph were going to make a snack run after walking Sunita home.

"Wait, why did Other-Leo and Casey have a fall divorce photoshoot?"

"Because they had a spring wedding. Duh."

Raph powerwalked passed the group and out the door, collapsing into laughter after passing the threshold.

Leo was talking all things sci-fi with his counterpart. Right now he was learning of the greatness that is the Jupiter Jim Extended Universe. Jitsu had made a comment about those movies not being good and then proceeded to fall asleep on the chair next to them.

"So next year they're coming out with the ninety-ninth movie! Which is setting up movie one hundred, because that has to be a bang, right? And-"

A fast beat song Leo had never heard before came from Primetime's phone and he dug around his chair looking for it.

"Hello, you are conversing with Leonardo?"

Leo tried not to laugh at the funny way Primetime said those words, clearly mocking someone. Suddenly Primetime stood up, "How long do we have? Uh-huh? Thanks."

Primetime hung up and stepped up on his chair, the Raphs returning at the same time. Primetime cupped his hands around his mouth and yelled, "PARTY'S OVER. VENUS CALLED AND BIG MAMA IS ON HER WAY. MOVE! MOVE! MOVE PEOPLE!"

Everyone jumped into action, throwing chairs without caution through a portal Primetime whipped up, sliding everything that was on the snack table into a trash bag, Donatello started ripping cables out of the screens. Someone shoved a blanket into Leo's hands and he confusedly threw it into the portal.

"What's happening?"

"Big Mama knows we're here!" Big Raph hollered over the commotion.

"And she's gonna be really ticked we used her arena without inviting her!" Mikey said as he yanked several cables out of the wall.

"Who's Big Mama?" Raph asked, also standing around confused.

"Move now, ask questions later!" Primetime shouted as he shook his father awake.

Green grabbed Leo's arm and pulled, "No time! Her car just pulled up!"

Leo was dragged into the portal and away from it, just in time to see everyone else fall out like an avalanche. The portal closed just as Leo heard a very feminine voice scream out "BOYS!"

There was laughter coming from behind the chair pile and Leo saw the fish-lady from earlier materialize out of thin air, phone in one hand and a mug in the other. "You should of seen your faces!"

"Piebald, did you tip off Big Mama?"

Piebald shrugged and took a sip from her mug, "Mayhaps."

A "Why?" came from the pile of bodies.

"Revenge. Leo knows what he did."

"LEO!" was chorused from the pile.

Piebald started laughing at Primetime's guilty face, which set off a chain reaction of laughs and sleep deprived giggles.
