It was another average day in Ponyville, which definitely means it's anything but normal compared to the rest of Equestria. Today in Twilight's castle were it's very owner as well as her best friends in one of several libraries, the group of ponies and dragon were surrounding the crystal mirror and looked almost ready to go through. Emphasis on almost since a question arose from a certain marshmallow-white unicorn, "So if I'm getting things in order we are to transform into some other bipedal species as well as. .regress in age?"

She asked her purple alicorn friend while being a tad disgusted at the thought of being treated like a filly again, Twilight simply nodded a bit sheepishly and responded, "Well it sounds weird when you say it like that but that's how it is. Any other questions?"

It took a moment as the group thought things over but just when Twilight was going to announce something an orange hoof shot up, this one clearly belonging to Applejack as she began to speak, "Now how are we going to get around there being two of us? Because I feel like I heard something from Spike about how two who're the same but different can't interact."

Then it got to being the dragon's turn to interject while he was busy putting on a surprisingly average sized backpack with Rarity's cutie mark, "That's a time travel thing AJ, though I'm not sure if anypony's ever confirmed that. Guess we'll be the first!"

This statement really got Twilight thinking about how that situation should be handled, but she ultimately decided that there shouldn't be any harm in there being two of her friends for a day. So now that everypony looks satisfied with whatever questions they may have as well as newfound knowledge of what's on the other side, Twilight flipped a switch with her magic and a moment later the machinery connected to the mirror produced a soft hum as the it went from something you'd find at Carousel Boutique to something truly deserving of a room dedicated to itself as evidenced by the purple swirly glow welcoming everypony to step through.

And just that they did, as well as bounce and fly in if you're Pinkie and Rainbow.

The transition between dimensions is that of a bright but not so blinding white that took on the form of an endless plain with a walkable surface that blends in perfectly with the sky around them. As the group kept moving forward they passed by a stylized three that looked like it came out of a movie, then a two, finally a one. As they passed by it they all assumed it was perfectly normal and just meant they were finally getting to their destination, everyone except Twilight and Spike who's never seen anything like this before but decided not to worry any of their friends just yet since there isn't anything to do in this space except move forward.

Like a door every portal leads somewhere and even a malfunctioning portal is no exception, where the seven of them ended up being a city that somehow feels bigger and. .brighter then Manehatten. The first thing everypony noticed is that unlike what Twilight told them, they were still the same species as they were before and Spike was the first to bring it up and proudly too as he exclaimed, "Alright! I'm not a dog!"

The group looked around and back to themselves in confusion, Pinkie just digging into her mane and holding a picture of her human equivalent in a hoof and sighing then putting it away. "Y'know this place seems awfully familiar." Fluttershy noted as she turned to Spike who's excitement lessened by the pegasus staring at him, though not using the stare just yet as she went on. "Spike, are we in your Power Ponies comic again?"

The idea was neat and anypony could see the reasoning behind Fluttershy's question though Rarity was quick to point out that, "If we were we'd have been wearing those costumes, and yet here we all are wearing nothing. Except that. .guard? Detective, maybe? I've never seen anypony wear something exactly like that before."

Standing right there was a white stallion with blue eyes and a yellow mane, a pegasus wearing a dark gray hat with a black rim alongside a golden symbol on the middle of it with a rook. He also donned a gray collar with a black tie that matched the hat perfectly, finishing the look with some sort of utility belt that has a wire coming out of it connecting to a walkie talkie somehow connected to the pony. "Nope, that's the common cop of the comic. Maybe we could ask him where we are?" Spike asked to nopony in particular as the rest of the group got the idea and approached the officer with Twilight being in the front and the first to speak.

"Excuse me, but we were heading somewhere but seemed to have gotten lost, if it's not too much trouble could you tell us where we are?"

The cop looked the group over for a moment, his gaze hardening at the sight of a unicorn and an alicorn but decided not to report anything just yet and answer the question. "This is the 1st ward of Cozy City - don't you know anything about the megalopolis?"

Flying a little lower than usual, Rainbow loudly whispered to Spike, "Ugh, what a crappy name. Ever heard of it?" The purple dragon shook his head without vocal response since his attention was on the cop and whatever crucial information he has. The cyan pegasus only somewhat cared as she went on a bit louder, "Who even names a place Cozy City?! It's like the setting of a story for foals!"

As Rainbow went on her mini-rant the cop was hearing this perfectly clear and spoke up, "You're all acting awfully suspicious - where did you say you came from?"

Not wanting to anger the cop at all, Twilight did her best to calm him down while Rainbow got the sign and did her best to stay silent but still grumbling something to herself. "Ponyville, of course! From a magic mirror in my castle that kind of. .malfunctioned."

The cop wasn't buying any of it and only seemed to make him more upset as he got in a stance that would've suited either a fight or a chase, "Ponyville?! Magic Mirrors?! Everyone around these parts knows that magic isn't real! Now you're all pretty shady - let's hear what you've been up to around here, and don't feed me any more lines!"

In a newfound state of shock and panic, Twilight wasn't sure what to do or what to say that could possibly clear up any misunderstanding and now he's speaking into that mic! 'WhatdoIdo? WhatdoIdo? WhatdoIdo?', the alicorn thought to herself on repeat not even noticing Rarity step forward looking a bit cross herself and with quite a lot to say, and his appearance being similar to Blueblood wasn't helping anypony. "Now you listen here! I'v-"

But her words were cut off by the thunder of hooves against pavement coming to face the group, another cop judging by the uniform. This one an earth pony with a blue coat and a dark blue mane that went well with the hat. That seemed to snap Twilight back to reality as she exclaimed, "M-m-more backup?!"

The pegasus cop wasn't having any of it seeing as he's pointing a hoof forward at the seven of them and yelled to his subordinate, "They're acting suspiciously! Arrest them immediately!" The earth pony cop nodded and responded seconds away from galloping after them, "Roger that!"

Thus the chase began with Rainbow making sure she wouldn't be caught as she yelled to her friends, "Oh crap, let's get out of here!" Without wasting a millisecond, the pegasus was already gone with only the rainbow highlights left over from her speed. The rest of the group galloped like their life depended on it with Fluttershy being the last to take off to apologize rather frantically to the cops, then dashed off while using her wings for boosts to have a better chance at catching up with her friends.

"Go! Don't let them get away!" The cops said to each other as they went after the seven, though the Mane 6 and Spike still had no idea where they're going so they kept moving forward along the road until they hit a dead end.

Even if several earth ponies and pegasi could be seen walking around, it's all in a direction that'll lead them right back to the infuriated police officers. "This can't really be a dead end, I simply can't be arrested! Who'll be there for Sweetie Belle?!" Rarity said while holding a foreleg in front of her eyes and looking away, if this were still Equestria she'd have landed on her coach by now.

"But it's not really a dead end." Rainbow and Twilight said at the same time, something that caused them to look at each other with a somewhat derpy grin then Twilight continued the statement as a solo act. "A quick glance and I can tell that this is some sort of portal, but weirdly enough it's just floating without a catalyst. But there isn't any time to think about it, as long as we're out of here! Everypony jump!"

A pair of pony cops were now lost on where the group they were chasing went, unaware of how they actually ended up in someplace that isn't Cozy City. Twilight and her friends were also unaware of a lot of stuff as well, just knowing that they're safe. "Why's it so bright?" The rainbow maned pegasus asked as she looked around the new place with everypony else just murmuring something to themselves.

"Where are we? I mean, it was a whole city just a moment ago and that meanie cop even called it a mega. .something!" Pinkie stated in a more subdued version of her usual cheerful and bounciness, clearly even she's interested in getting to the bottom of this mystery.

"Well if you look behind you, darling, you'd find a screen. I have a feeling we're in a movie theatre." While their eyes adjusted to the new lighting they could spot what looked to be hundreds of chairs, oddly enough only the first row looked to be for ponies, but the message was still sent as the same unicorn gasped, "I can't believe it! If that portal from before led us here, then were we not apart of a movie?! To think our debut on the silver screen would be like that! I demand to speak with whoever's in charge, I simply MUST star in a certain. .detective film."

Applejack simply nodded, "You're right about one thing, I think it'd do us best to find out if anypony's here. Rainbow and Fluttershy, you two take to the skies and look for anypony between these seats!" Turning towards Rainbow, AJ just scratched her hat in confusion on where Fluttershy is. The farm girl knows her well enough that she wouldn't just run off instantly, meaning that, "June bugs on a filly's muzzle! Fluttershy's still in the movie!"

Twilight, however, still had her doubts and also felt it'd be right to scan the area first. So she spoke up about it, "Well who's to say that she didn't keep running and might be somewhere in this theatre? I think we should look around before making any irrational decisions. After all, those cops may still be on the look out for us.." At this point AJ was ready to start an argument but what Twilight brought up did sound like something Fluttershy would do, besides it isn't easy to catch a pegasus.

So she conceded, "Alright sugarcube, let's look around for her in this place then."

So they all went looking throughout the theatre in search of Fluttershy, any one of them even calling out her name every now and then with no answer from the pegasus they're looking for. So with no sign of her in this room they moved onto the next, that being the concession stand. "You know I'm getting a feeling that this cinema is actually abandoned." Rarity piped up to break the silence as she and her friends kept up the search, in response Pinkie just asked, "Why's that?" This got Rarity to point at the prices listed with a hoof, "These! They're actually fairly priced! What kind of a movie theatre has popcorn for as much as a store sells it for?! Why can't they all be like this?" She said that last bit a tad under her breath, the whole thing causing Twilight to roll her eyes as the group kept moving on.

Next up in the list of places to look for Fluttershy: The Ticket Booth! Believe it or not, but she isn't here either but something else about it caught Twilight's interest. That being the machine used to dispense tickets, oddly enough there's two holes for slips of paper to go through, and if one were to look close enough they'd find small pictures carved into it that showed a slip of paper going into it, and another going out. Do you need a reservation for a simple trip to the movies? Hopefully there's going to be an explanation for that soon.

Now they've ended up at a door that reads 'STAFF ONLY' in big letters on a pseudo-clapperboard. Even if Twilight would twist the door open with her magic, it wouldn't budge. Applejack just read a bit closer into what the sign has to say for nopony in particular, "Authorized Personnel Only, makes sense that it'd be locked."

Twilight responded, "I may have a spell for forcing it open though, though I guess that wouldn't help in our search for Fluttershy, now would it?" The orange earth pony just nodded as they trotted along.

Seems now they've found themselves in a projection room and at least one pink party pony is interested in whatever's in here that isn't Fluttershy since that mare isn't here either. "Murder on the Owl Express, Picture Perfect, Train Rush, The Big Parade. They look like they're made by two completely different directors but star the same kid, wonder how that happened. Got any ideas, big guy?" Looking up they all came to face some sort of creature that's entirely black with only a blue and white spotted tie and a yellow mask. Expressionless and devoid of life would best describe it, but Pinkie would at least try to get it to emote. "Come on, work with me here! Picture this, you're sneaking through a movie studio that's run by penguins and owls! Go!" Yet what might as well be a giant doll just stood there.

"Pinkie darling, don't you think we should keep up the search instead of. .act with dolls?" Rarity did her best to persuade her wacky and uncharacteristic friend, and it worked since the pink mare immediately dropped it as they all went to go somewhere else in the theatre.

The last place to search is the main lobby, and by that I mean they were hoping Fluttershy would be relaxing on one of the many couches, but she still isn't there and instead Rarity laid down on it with Spike joining her on a handle, it's not the usual couch but this'll do. "It's no use, we've been spirited away and we can't find her!" The unicorn cried out while putting a foreleg in front of her eyes once more, though if she's actually crying or being dramatic it could go either way.

Not wanting to deal with either of those, Rainbow felt it'd be best to speak up, "But don't you think it's weird that nopony else is here? All we found was some weird doll, but who put it there? Seriously! How'd we end up here?! And how do we get out?!" Seems she got more heated as she went on, as if the cinema is closing in on her with each passing second.

"Well how about those doors? They're locking us in, why don't we have Twilight try to unlock them when we get Fluttershy back?" As they walked over to where Pinkie is, they all found exactly that. Several locks on the door, strangely enough with themes. A steel lock shaped like hoof-cuffs with police tape on it at the bottom, one that looks like it's made of dinosaur bones below a futuristic looking one, that one being at the top, and finally a space themed one with stars scattered about it throughout the middle.

"Well if she's nowhere in here, I think it's about time we check the movie we were in." Twilight spoke as she headed off to where they all first were.

"Y'know now that I look around it kind of feels creepy, like some zombie could pop out at any moment.." Dash said to herself, shuddering at the memory of her candy prank gone wrong.

But she couldn't dwell on the past for too long since Pinkie Pie shouted something that easily got her attention, "Hey! Somepony's there!"

Two of them to be exact, the first being a light brown earth pony filly with a black mane that has purple at the tips. She wore a red cape with a pattern on it that resembled a wave of water. Not much more to mention of this one involving her freckled face. Next up is a cyan pegasus colt with an unkempt dark grey mane, oddly enough with red tips only on his tail. He also wore something; a dark-blue, long-sleeve, button-up shirt with an extra dark grey set of pants. Each piece of clothing having holes cut out for his wings and tail. Finally a dark blue hat to complete the look, of what? Not even I, the narrator, am sure. All I can really say is that the two are no older then teenagers and look excited at the appearance of others besides the two here.

"Guess that answers one question, Dashie!" Pinkie said as she trotted to the two ponies she doesn't recognize and turned to face Rainbow, just to playfully stick her tongue out. Then she retracted her tongue and turned to face the two, "So what're your names? I'm Pinkie Pie!"

The pegasus was the first to speak up with a smile, as if being in Pinkie's presence is enough for that, or maybe he already knew her and is excited to meet her. "Well this is Cap."

"And right besides me is Pikpik!" The earth pony now known as Cap continued, that getting a light chuckle out of the two as if they've been friends for quite a while.

Being the princess of friendship, Twilight couldn't help but smile at their display, and by the looks of it neither could the rest of her friends, especially Pinkie. But the alicorn still had something to ask them so she stepped up and asked away, "Excuse me, but have you two seen our friend Fluttershy? She's a yellow pegasus with a pink mane and three butterflies for a cutie mark."

Pikpik quickly replied with a hint of sorrow in his voice near the end of his statement, as if he wanted to go after her but couldn't. "Of course, though it's really unfortunate. I saw her get taken by those cops, I hope someone rescues her soon, I'm not sure if she'll do well alone like that." Hearing that Twilight turned back to her friends as her gaze hardened with determination.

"Well girls, are we ready to save Fluttershy?"

"Put me in, coach!"

"I'll give them something a lot bigger to worry about then suspicion!"

"Heck Yeah!"

"Yee-haw!" Everypony exclaimed, clearly ready to rescue their missing friend. Yet Spike stayed silent. When they were done with their rallies and war cries, he spoke up.

"Actually Twilight, I think it'd be best if I stayed back and provided support. After all, most of the adventuring stuff you do just isn't for me." That was something Twilight was perfectly fine with and actually kind of glad about, knowing that he'd be safe here and could help out in other ways.

So she walked up to her draconic little brother and patted his head with a playful grin, "It's what you've done before, why stop now just because we're in an interdimensional theatre?" He just smiled back and ran off to the concession stand, hoping to find some gems.

With hooves making thunderous noise as they galloped to the screen, they stopped when the filly yelled, "Hold it!" Of course everypony halted and looked at her in confusion, to which she responded to their faces with, "Don't even try to fight Fillyglow, not yet anyway. Anyway I'm off to raid the concession stand for it's candy supply!" Cap started off rather seriously, but that tone quickly died out before she went looking for as many sweets as she could handle. That and Pikpik who disappeared, most likely wherever Spike is. The Mane 6 just looked to each other then jumped back into that city within the movie.

Author's Note

Y'know I've actually never seen Equestria Girls and I probably never will so I'm going off the assumption that only Twilight and Spike went through the portal
Anyway I hope I did good for my first ever fanfic
