The Rainbooms are practicing another song, and as you guys finish, Twilight, Sunset, Rainbow, AJ, Rarity, Flutters, and Pinkie pony up again, and turn back to normal after finishing. 

Rainbow: Man I hope the Friendship Games have a music competition, because we would totally rock it! 

She shredded on her guitar after finishing her sentence. 

(Y/N): We're supposed to keep the magic out, remember Rainbow? 

Rainbow: (rolling her eyes) Yeah, I know. 

Yang: You know Dash, I'm just saying this, there's listening, and then there's following through on it. 

Ruby: Didn't you try to pick a fight with a certain God of Destruction? 

Yang: Hey, would you let an asshole like him go through with blowing up a planet just because he wanted to fight (Y/N)? 

Ruby: Okay, yeah, that is a good point. 

Rarity: It's easier said than done anyway. I mean, in a place like Equestria, magic does whatever you want. But- 

Sunset: It isn't Equestria. 

Applejack: You okay Sunset? You seem nervous. 

Sunset: I don't know. We haven't come to any conclusions so far. 

Twilight: Don't worry about it, we'll figure something out. At least I hope. 

Rarity: Cheer up Sunset, I know what will make you feel better! 

Applejack turned to her girlfriend with a concerned look. 

Applejack: What did you do this time Rarity? 

Rarity: Well- 

She quickly took off and dragged in a massive chest full of outfits she had made. 

(Y/N): HOLY CRAP RARITY! 

Weiss: You made all of these? This is incredible! 

There were jumpsuits with colors that fit everyone for the Friendship Games. 

Rarity: I had some time on my hands. WAnd I made a few options for uniforms. 

Rainbow: You really didn't have to do that. 

Rarity: I know. 

Applejack: No, you really didn't have to. 

Rarity: I know! HAHAHAHAHAHAHAHAHAHAHAHA! 

(Y/N): That's our Rarity! 

Just outside... 

A bunch of buses arrived with the Crystal Prep Students coming out. 

And Celestia came face to face with Cinch. 

Celestia: Vice-Principal Luna can help your students get settled, if you'd like me to show you around, Principal Cinch. There have been quite a few changes since your last visit.

Cinch: Oh yes, Celestia. I'm sure that would be fascinating. 

Luna on the other hand came face to face with Cadence. 

Luna: It's always a pleasure to see you again, Cadence. Even if it means another defeat. 

Cadence: Thank you, Luna. 

The two hugged each other. 

Cadence: But I heard it's not going to be so easy this time. 

Sci-Twi stuck her head out of the doorway with her backpack slung open a bit as breathing room for Doggy Spike. 

She adjusted her glasses and was about to step out, only for- 

Indigo: Coming through! 

Indigo knocked Sci-Twi out of the way, causing her to fall off of the steps! And right onto Sunny!

Sunny: Seriously? 

Sci-Twi: Oh, sorry. 

She got up and nearly runs into Sour. 

Sci-Twi: Sorry, after you. 

Sour: Aww how sweet. (suddenly vicious) I've got my eyes on you. 

Sci-Twi: Right ... right. 

Sugarcoat: Geez, door matting much? 

All of the CHS Students see Sci-Twi enter, and were in shock! 

Lyra and Bonbon 

Lyra: Wait a second, Bonbon, isn't that- 

Bonbon: Twilight? But she's already here. 

Male Student: Holy crap, that girl looks just like Twilight! 

Rocker: Twilight? 

Drama Kid: She actually looks like- 

All the students were making a big fuss of it! 

Sci-Twi: Uh ... hi ... everyone ... I ... gotta go! 

She takes off super quickly. 

Back with the Rainbooms... 

You guys went through all of Rarity's outfits one at a time. 

Blake: Really Rarity, why would you put so much time and effort into outfits were probably not going to wear? 

Applejack: Yeah, you're going to exhaust yourself before the games even start! 

Rarity: Don't be silly, you two. Putting effort into my clothes is what I live for. And of course spending time with those I love fills me with energy! 

She ponied up without warning! 

Twilight: Uh ... red flag! That's a big red flag! 

(Y/N): Rarity, tone it down! 

Sci-Twi's device goes nuts and detects Rarity. 

Then all of a sudden a burst of energy came out and drained Rarity dry! 

Rarity: You know, I ... could use a tiny break. 

Applejack: Come on. 

Applejack helped up her girlfriend, with the fashionista blushing hard at being in the arms of her lover. 

Sci-Twi: So this is where it was coming fr- 

(Y/N): AGH! IT'S HER! 

Ruby: THE OTHER TWILIGHT?! 

Sunset: SO IT IS! 

Pinkie: Hmm ... the resemblance is uncanny. 

Pinkie got up close and inspected Sci-Twi in all areas. 

Pinkie: Yep, definitely looks like her. 

Twilight approached her human counterpart. 

Sci-Twi was in complete shock too. 

Sci-Twi: You're ... me. 

Twilight: Uh ... yeah. And you're me too. 

The two scratched their chins in confusion as they started to copy each other's movements. 

(Y/N): And now it's a clash of cuteness! 

Ruby: Yeah, both of them are super cute! 

Rainbow: Wait, if this is Twilight's counterpart from this world, then does she have- 

Spike popped out of Sci-Twi's backpack. 

Rainbow: Yep, there's Spike. 

Fluttershy: SPIKE! 

Fluttershy got so excited she ran up to hug and pet him. 

Sci-Twi: Wait, you know about my dog too? 

Yang: Girlfriend, it's a long long story. 

Celestia and Cinch then walk in. 

Celestia: And the music program has really taken- WHAT THE?! 

She had a massive confused look on her face. 

(Y/N): And now Celesita knows. 

Celestia: Another Twilight? 

Sci-Twi: Okay, this is ridiculous. 

Twilight: We get it already. We're the exact same. 

Cinch: Ahem, yes I must apologize for the curiosity of my prize student. 

Celestia: She's your student? 

Cinch: Correct. The smart ones are usually curious. I'll return her to check in with the rest of her classmates. 

She escorted Sci-Twi out. 

Celestia: That's very interesting. Twilight, do you have a twin sister? 

Twilight: No, if I did I would have said so. 

Pinkie: Besides, it's the Twilight from this world since it couldn't possibly be the Twilight from Equestria since our Twilight is standing right here, attends both CHS and Beacon, and she doesn't even wear glasses. 

Yang: I wonder if that Twilight is scared of la- 

Twilight: YANG! Don't say that word! 

She shuddered, thinking of ladybugs. 

Celestia: Right. I'll just leave you all to it then. 

Celestia walked off. 

Back with Sci-Twi... 

Sci-Twi: Sorry Principal Cinch, I was just following these strange readings, and it lead me to them. 

Cinch: Twilight, what you do in your free time is your business. But while you're here, all of Crystal Prep requires your complete focus. 

Sci-Twi: But there's another me. Right there! You saw her! 

Cinch: It's obviously a trick to confuse you. 

Sci-Twi: Doesn't look like it. She seemed really real! 

Cinch: I don't know what they're playing at, but I guarantee it isn't to help us win. 

Back with the Rainbooms... 

Rarity: So, this world's Twilight goes to Crystal Prep? 

Rainbow: Man this sucks! We have another Twilight who's playing against us. Totally out of character for you Twi. 

Twilight: I'm just as uncomfortable about this as all of you are. 

Fluttershy: Don't worry about it Twilight, we'll figure this out somehow. 

Sunset: Yeah, we'll figure it out. I mean it's not like we know exactly how we're going to control ponying it up. Even with all the magic training we've gotten. And now this big competition has come in on us. Not to mention, Najimi could have told us this sooner. If she really is a goddess, then she should know exactly what the hell is going to happen! SO WHY THE FUCK DID SHE- 

(Y/N): WHOA! Sunset, calm down. 

You started to rub her shoulders. 

Sunset: Sorry, I'm sorry. It's just, we haven't figured anything out yet, and it's driving me crazy. Thanks (Y/N). 

You kissed her on the cheek. 

(Y/N): Anytime, Sunshine. 

Ruby: So, any suggestions then? 

Yang: Isn't it obvious? We show these snobby dickheads that we got- 

Pinkie: No! Yang, don't finish that. 

Yang: HEY! PINKIE LET ME HAVE THIS! 

Pinkie: Your puns stink and you know it! Rotten comedy! They're just going to bomb! 

(Y/N): Hahahahaha! 

Rainbooms: (except Yang) HAHAHAHAHAHAHAHAHAHA! 

Weiss: Okay, that was a good one. 

Yang: (sticking tongue out at Pinkie) Whatever. 

Soon... 

All the students of CHS and Crystal Prep are in the gymnasium as there's a welcoming party being thrown before the games start. 

You all saw Sci-Twi. 

(Y/N): Okay, I'll go and talk to her. 

You walked up to Sci-Twi. 

(Y/N): So, Human ... Twilight ... 

Sci-Twi: (blushing) Oh... hi there. You're (Y/N) right? That's what I heard so many others call you. 

(Y/N): Yeah. What's that device you got there? 

Sci-Twi: Well, it- 

Indigo: Hey, what are you doing? 

The Shadowbolts appeared. 

(Y/N): Just making conversation with your teammate? 

Sunny: Why? 

(Y/N): Just having a friendly conversation. 

Sugarcoat: Why so you could figure out how to beat us? 

Applejack then came in. 

Applejack: Alright, settle down. Let's not get too competitive. 

Sugarcoat: The Games aren't competitive. We've never lost after all. 

Fluttershy: Hey that's not very nice! 

Ruby: Yeah! Don't brag about your victory in front of someone else's face! Didn't your Mom teach you th- 

Sunny: Sorry Red, the Games aren't about being nice. 

The girls had a stand off as you knew something bad was going to happen. 

(Y/N): Hey, Pinkie. Why don't you take over? 

Pinkie: Okay! 

Pinkie zipped up to Sc-Twi! 

Sci-Twi: Uh ... hi. 

Pinkie: Hi there other Twilight! I'm Pinkie Pie! 

Sci-Twi: Hi ... Pinkie ... Pie. 

Pinkie: You know, you look so much like our good friend Twilight over there. 

She pointed to Twilight who nervously smiled and waved at her other self. 

Sci-Twi: Yeah ... I know. 

She took out her detector. 

Pinkie: What is that? 

Sci-Twi: A spectrometer of sorts. I built it to track EM frequencies. 

Pinkie: Yeah? 

Sci-Twi: And it also contains anomalies. 

Pinkie: Huh? 

Sci-Twi: It measures things. 

Pinkie: Like this party? Because I know something is definitely missing. 

She pointed to everyone sitting dully, one person sleeping, and Vinyl slumping over her DJ turntable. 

Sci-Twi: Yeah, not that much of a party to me. 

Pinkie: But I have an idea! COME ON! 

She dragged Sci-Twi along as Celestia was about to speak. 

Celestia: Hello, everyone. I'd like to take this opportunity to greet all of our visitors from Crystal Prep Academy and welcome them to CHS.

Pinkie had brought out two massive party cannons! 

Sci-Twi: WHAT IN THE WORLD ARE THESE?! 

Pinkie: My party cannons! 

Celestia: And lastly, I would like to recognize the twelve students that CHS has elected to compete. I don't think we could have chosen a better group to represent the excellence, sportsmanship, and friendship the Games stand for.

Pinkie had Sci-Twi help her out with the cannons! 

Sci-Twi: Are you sure about this? 

Pinkie had a determined game face on. 

Pinkie: Definitely! 

Massive blasts came out as suddenly the party got livelier with everyone having no need for loyalty or rivalry. 

Sci-Twi ducked for cover, with her glasses coming off, and Pinkie was bouncing everywhere! 

Suddenly Sci-Twi's device activated and sucked Pinkie dry! 

Pinkie: Aww. I'm all party pooped. 

The Raibooms took notice of this. 

Cinch then took the stage while whipping off confetti fro her outfit and polishing her glasses. 

Cinch: Ahem. I'd like to thank Principal Celestia for her unconventional welcome. It's been four years since the last Friendship Games, but it feels as though nothing has changed. Canterlot High continues to pick its competitors in a popularity contest—and Crystal Prep continues to field its top twelve students.  It is a comfort to know that even after so many years of losses, your school remains committed to its ideals, however misguided they may be. I wish you all the best of luck, regardless of the inevitable outcome.

You ten went up to comfort Pinkie. 

(Y/N): Hey Pinkie, that was pretty great what you did. 

Ruby: Yeah! You brought life to the party! Like usual. 

Rarity: Yes, if only that Principal Cinch hadn't frozen it again. 

(Y/N): She's too much like Ms. Heinous of St. Olga's. 

Twilight: (shuddering) Man ... that woman was horrible. At least we don't have to worry about her again. 

Sunset: Say Pinkie, what happened to you? You look almost like Rarity did before. 

Pinkie: I don't know. Everyone started having fun after Twilight and I fired the party cannons and I ponied up. 

Twilight: How did it happen? And ... where is other me? 

(Y/N): Looks like she took off. But, maybe- 

You thought of that device. 

(Y/N): I need to call Dr. Vegapunk. Maybe he might be able to figure this out.
