Thanks to the fact that no one was seriously injured during the run of the invasion, Sky and Tello were able to jump right back to finishing the portal to Ninjago.

For the first test showed up everyone who helped. Donnie's lab was a bit crowded with scientists from various dimensions, but it didn't seem like anyone was especially bothered.

Tello and Lunella turned on the machine and waited in anticipation.

Everyone else was standing 4 meters away from the portal and everything and everyone inside that 4 meter perimeter around the machine has been screwed tightly to the floor. The two main geniuses calculated that the gravitational pull from a rift in the fabric of reality might be great, but the one who made them take all these safety measures was Stanford Pines.

The portal swirled to life in a mix of purple and pink. The pull into it was strong, but the safety measures, in the form of an ankle cuff and chain screwed to the floor, were enough to keep Tello and Lunella from flying into an interworldly portal in the beta testing phase.

After approximately 20 minutes of various tests, notes and equations, the main geniuses turned off the machine and took off their 'safety cuffs'.

These 'hangouts', as Leo described them, happened five more times before Sky was finally let in on the role of 'dummy' who would cross to the other side and confirm it was her world. Safety measures were taken here also, in form of an actual crash test mannequin with a camera strapped to its head roped to the nearest screwed to the floor table and thrown into the portal. Three times.

After confirming, four times, the other side of the portal was, in fact, Ninjago, the Hamato siblings prepared for a mandatory session of interdimensional tourism.

But when they stepped out in the Monastery all that welcomed them was eerie silence.

"No one's here." All of Sky's friends and family either got captured by the CEO or ran. She was really praying it was the second option.

She tried calling Kai, with no result. The same with Lloyd. Finally, after a while, Mei answered. "Who is it?" Her voice was... not quite hostile, but very hesitant and sounded a bit like a growl.

What happened? Has someone else called Mei trying to imitate Sky?

"Mei?" She settled for the safest and simplest option.

In response a hitched breath came from the other side of the call.

"Sky? Is- Is that you?" Mei almost whispered. Now Sky regret not having any kind of special password with Mei.

"Yeah. Where are you? The Monastery is completely empty." Sky asked, her tone matching Mei's as closely as it could, while ignoring Tello in the background exploring the huge space.

"In the city. Where the resistance." So garbage truck base. Got it.

"Got it. I'll be there shortly with some friends. See you." That must've been the softest 'see you' she's ever given anyone.

"Just. Look out and don't get crystallized. Okay?" Oh, so it was season 16. It made sense.

"Thanks for the info." She hung up and sighed. The overlord's army is made of vengestone which blocks any body tied powers. That, of course, includes shapeshifting. Yay.

"Okay, I know where my family is. Also the city's been taken over by an army of warriors I can't beat and what are basically zombies. You wanna go back home?" She did account for the possibility that the turtles might not want to stay in Ninjago.

"Nah." Okay, that was not a response she was ready for. "It would be irresponsible to let you go alone. Besides, I wanted to explore this world and explore I will."

Huh. Guess they were going with her. She had a habit of forgetting how big of a deal the invasion wasn't.

"Okay then. Let's go."

-

After surviving the sole number of steps on the stair down, the group entered the city perimeter. It looked... quiet. Not even dead, just quiet.

But maybe it was just Sky's point of view, since she knew somewhere there, just out of sight, the people of this city were surviving, crawling, like cockroaches. Impossible to kill once and for all.

"Everyone stay silent. And stay away from the giant island floating in the sky." She hadn't seen the lair of the CEO yet, but didn't wanna take any risks.

"Is this city always like this?" Tello asked, whispering.

"No. Sometimes it's full of light and sound of all kinds. But when an apocalypse strikes, everyone hides and survives in the shadows." Sky answered, shrugging and led the turtles further into the city.

The would-in-s9-be-resistance-base was, unfortunately, almost on the other side of this FSM forsaken city.

"You said that like it was not the first apocalypse." Leo stated, surprised. And he was absolutely right.

"Well, it isn't. There were... I think three? And I'm not counting the giant snake, the fights with a motorcycle gang led by a prince, the narrowly avoided giant fight with embodiment of hell, the city getting ripped apart and reformed in the sky in the alternate timeline, a historian who kidnapped people and built his own army to go back in time and kill my siblings' parents or half of the city's population getting sucked into a videogame for, like, a week." Wow. Now that she said that out loud, Sky realized how thoroughly fucked up her life was.

When she turned back to glance at the four siblings, their jaws were on the floor.

"And here I thought we had a crazy life." Mikey commented.

Sky wanted to say something more, but quickly discovered they were at their destination.

She went in through a big garage door and let in the turtles. She's actually been here before with Mei. A few years ago they were checking this place out, out of boredom.

"Welcome to the hideout of the resistance. I guess. I don't really know."

"Sky!" A familiar shout came from behind her and a pair of strong, green sleeved arms wrapped around her in a tight hug. She couldn't help but smile.

"Mei! I've missed you so much!" She hugged Mei back. Until she realized four pairs of eyes were still on her.

"Oh, right. Mei, the turtles. Turtles, Mei." She introduced the bunch and hoped Mei wasn't gonna say anything too bad, embarassing or clearly pointing to her knowing the turtles already.

"Oh my gosh! Are you Mikey?!" There it goes. Hopes are out the window. Mei jumped to the youngest and started checking out his stickers and shell. "He's so cute!" She turned back to Sky, who sighed deeply, but smiled nonetheless. She'll have so much explaining to do.

Every other turtle, one by one, got squished, poked and complemented by Mei, except for one. Donnie was greeted only by her big, cute smile and lots of compliments and questions.

Well, if the rest didn't realize something was going on before, they definitely realized now. "Wait, how do you know us?" Leo asked suspicious. But before any of the girls could answer, Mei shouted "What happened to your arm?!"

Immediately she was right next to Sky, examining the scars. There was no point in hiding anything.

"The movie." Sky sighed. "The movie happened."

Mei understood immediately, not asking any more questions.

This seemed to confuse Mikey, Raph and Leo even further. "What? What do you mean 'the movie'?"

Sky sighed. It was time to reveal the truth. Or she could just never speak with them again....

Nah.

"So... Okay, to be perfectly honest, I don't fully get how this works." Sky pulled out her phone and found Monkie Kid episode 3. 'Coming Home'. "Trigger Warning: Mei's past and MK being stupid." She passed the phone to Leo. He angled it so that Mikey and Raph could also watch.

"Wait, is that the episode where Mei gets the Dragon Blade?" Donnie, discreetly asked. Okay, not that discreetly, because mei heard it.

"I'm sorry, what?"

"Uhhhmmmmmm I maybe showed them the show...." Sky choked out sheepishly.

"So, let me get this straight. You introduced Donnie to the show, but not the rest?" Mei raised her eyebrow, but didn't say anything else.

That doesn't mean the 'you really are down bad' wasn't heard loud and clear.

"Okay, now" Sky took the phone out of Leo's hands upon hearing the closing theme. "look." She pointed to Mei.

"Yes, that's the same person you just saw on the screen. She is in an animated show." Sky tried to simplify things greatly.

"That's also the deal with you." She could see the shock on their faces. "The show is called 'Rise of the Teenage Mutant Ninja Turtles. There are two seasons and a movie. About you."

She took time for the three to really get the idea.

"..."

"And?"

"Hi! We're back!" Before the turtles could respond in any way other than staring into the void, Lloyd's voice rang through the building.

"Lloyd?!" Sky just had to run up to him and maybe a bit squeeze him until he couldn't breathe anymore.

"Sky?! I thought you were dead!" He hugged her back.

"Okay, before this gets too mushy, who else is here and not crystalized?" Sky broke the hug and accidentally quoted Leo's line from the movie, much to blue turtle's shock.

"Uh, there's me, Mei, Liv, Gami and Rumi."

"I'm guessing that Cole, Kai, Jay and Zane got crystalized immediately, because they ran straight into a battle, without any actual idea of what would happen." Sky deadpanned, making Lloyd snicker a bit.

"Yeah."

"Why are you laughing? We're in the middle of a literal apocalypse and you're joking around about your friends getting... possessed I guess." Raph spoke up. Right. The big worrywart.

"Eh, if we defeat the big bad, they'll go back to normal. That's just how it works." Sky shrugged. "Besides, apocalypse or not, we can joke around. Especially when something funny happens. It becomes normal after a while."

The apocalypse doesn't mean you can't poke fun at your brother. Everyone knows that.

"So, we need to strike the CEO. Any idea how to do that?"

"We have a plan. We were meant to go tomorrow, only the five of us, but you can tag along if you'd like." Mei said, ignoring the turtles' confused looks at the mention of the CEO.

"You wanna stay and kick another baddie's ass, or go back home?" Sky looked at the turtles.

"Well, it sounds like a big deal. We're in." Those words kind of surprised Sky. Right. No one was seriously hurt during the movie. No one almost died.

"Great."

-

"I should probably warn you that Rain is my clone, knows many things I know and has the same powers." Sky warned the turtles. "Good news: only one blow delivered by me and she'll cease to exist! Bad news: the same applies to me."

She didn't give time for the four to marinate the information in their heads, before she said "Okay, let's go." and stepped out onto the roof.

The city looked empty and devastated, like almost every other week. That's why being an engineer in this city guaranteed you a stable income and so many building companies to choose from.

"Hey hey, hey I came back!" Sky pulled a megaphone out of her pocket dimension and started screaming at the floating island - the CEO headquarters. Or, how the rebellion dubbed it, 'The Office'.

"Oh, córa marnotrawna powraca!" Rain walked out of the building and to the edge of the island. "How did you even come back?!"

Instead of answering, Sky just called the turtles to get out of hiding on the staircase leading to the roof.

She could hear Rain gasp. "No!"

"Yes!"

"They're an unfair advantage! I call to remove Donnie from this battle!" Rain pretended to throw a bit of a tantrum, much to the turtles' surprise.

Sky ignored Leo's "Why are they an unfair advantage, but not me?" in favor of "No!" and a sweet smile.

"I should've left you in 2012 instead! At least you wouldn't come back!" The spite and rage spilling from black haired girl's lips was enough to convince Sky she was doing a great job distracting her and, possibly, the rest of the CEO, still hidden in the Office.

"Rise and 2012 are parallel realms! That wouldn't have worked!" She laughed, half at Rain's growing anger, half at the fact that three of the turtles probably didn't have any idea what she was talking about.

"Okay, enough!" Rain screamed and pointed at the group of five standing on the roof. "Tear them apart!" She shouted and a few figures shot out of the Office. "You can leave the purple one alive. We'll give them funding and some uranium and they'll work for us."

"They won't and you know it!" Sky had to object. She hasn't ever met anyone more loyal than Tello.

"Then we'll break 'em. One way or another." Rain just shrugged.

Kalmaar and Nick jumped down to attack. But they were, fortunately, no match for the five heroes. Well, they would've been if Rain didn't join in. In her quadrupedal white and pink dragon form she was a huge distraction. Or maybe even the main boss.

"You should've stayed in the Prison Dimension!" She screamed out while trying to bite off Leo's head. He just looked at her confused.

"Wrong." Sky smiled, trying to bite into her neck in their own dragon form. Rain dodged, to Sky's annoyance.

"Ha! You really tried-?" She got cut off by a loud crash and Lloyd landing on her snout. "What the-" She got cut off again, by the Overlord/Crystal King landing on the roof.

"Sorry, gotta go." LLoyd said and jumped down to fight the big bad himself.

"Okay, that was-" Third time wasn't the charm. Rain got cut off by the teeth in her neck. Teeth of a certain blue dragon. "Oh fuck you." She managed to deadpan before she poofed out of existence.

Now looking around, Sky saw that every villain in sight was either unconscious or tied up, except for the Crystal King, who was about to be.

"Ninja Go!" Lloyd screamed and delivered the final blow, finally defeating the evil, as he was supposed to all those years ago.

-

"That was tiring. Wanna crash in the Monastery?" Sky approached the turtles. They were all bruised and scraped here and there, but over all they were just exhausted. No wonder. Kalmaar and Nick were joined by Pythor and Chen early on in the battle when Crystal King showed up.

"Yeah, I guess we could do that."

-

The four turtle siblings ended up staying over a few days and helping out with bringing the city back into its normal condition.

"Goodbye!" The four were about to step through the portal back to their world, when Donnie suddenly stopped in their tracks.

They ran back up to Sky and handed her some papers. She immediately understood she was meant to sign it. Discreetly reading every fifth word, she understood it was something about cloning?

She signed, shrugging. And gave it back to Tello, who gave her a smile and jumped into the portal gracefully.

Wonder what hijinks awaited in the future?

-

It was a normal day at the Monastery.Well, up until the point the Mailman arrived.
