Clone's POV:
The job was simple, get to the girls after they get to the bridge, Check. Introduce myself as a proxy for Jack and guide them to the castle's secret entrance, double check. Lastly, escort them to the chamber of the elements... Yeah, there's a sliiiight hiccup. Sheesh, how much trouble could there be between episodes!? I think my original self should have asked what the hell was going through the original creator's mind when they bumped up the dificulty level to ABSOLUTE ELEVEN! But I digress.

Twilight: "It's the final stretch girls, the elements are definitely close."

RD: "This place has nice duds for old ruins."

I smirked at the compliments. "Thank you, my friends try to keep this place in one piece for the last thousand years or so."

AJ: "You're over a thousand years old? Well hush my mouth, you look good for your age."

Rarity: "I'll say, he certainly has that charm of a mature stallion."

"Merci madmoizelle-" BOOM! The side of the wall caved in from an explosion, I'm gonna need to remind myself that the walls will need some magical reinforcements. Oh and standing there in the air was possibly the most pissed off Alicorn I would see for the rest of my short existence, the princess of the nightmares and darkness, Nightmare Moon. "Girls, I'm gonna need you to run to the chamber. The critters will guide you to the elements."

RD: "No way, I ain't running from a fight- OOF!" She, bless her brave soul, got roped up and was now being dragged by AJ.

AJ:"Rainbow, when a demonic Alicorn tells you to run, YOU RUN!" And they left through the halls of this great castle.

Now all that's left was the pissed off dark alicorn and a clone of... Well me. I'm about to get my ass kicked. "You know, being sent to the moon really did wonders for your complexion, you got a really nice tan out of it-" BOOOM!

Mane six POV:

Rarity"What was that!?"

Fluttershy: "Oh dear, I hope Mr Demon Lord didn't get disintegrated!"

RD: "You kidding? Guys like him are too cocky to die! ... I hope." Though one thing that bothered her was how familiar his voice was, like she challenged him to a race at one point... She puts the thought on hold as right now they need to focus on surviving the night.

Twilight:"Come on, we got to get to the chamber!"

AJ: "But we have no idea where it could be, and what kind of critters- WHOA!" Bats swooped down, giving the cowgirl a fright.

Fluttershy: "Don't be afraid, these bats are friendly! They're trying to point us in the right direction! This way!" Knowing not to argue with the animal poney, they followed Fluttershy who was being guided by the bats of the castle.

Main character POV:

I had to step up my pace as I was practically too far away from the castle. "I can't believe I was so stupid as to take the bait, fuck! If those girls get hurt I'll never forgive myself!" I was so focused on getting there that I forgot to land on my hooves and instead crashed with my face in the pavement. "Ouch! Evergreen, the castle has an intruder!"

"And just when I had the bricks refurbished. I'll send security ASAP!"

We're going to be needing a lot more than security, we need an entire SWAT team! I shook off my stunned state and head straight to the chamber that held the spheres. "Tell the security team that the demon lord is on his way to the elements of harmony!" I ran at top speed on my hooves, hoping to Buddha, Zues or any other god that's listening that I'll make it in time. Along the way I was hearing a series of explosions getting closer and closer... I think my clone is having a hard time-

My clone: "FOR THE LOVE OF THE GODS KILL ME ALREADY, EXISTENCE IS PAAAAAIN!

Yep, he's engaged in receiving a beat down. Damn I could even feel his pain! I sprinted as fast as possible through the hallways, hoping to any gods, for once in my life, that I get there on time.

Good news on that, I was able to reach the girls, although on the bad news, so has Nightmare Moon and she was dragging my clone by the ankles. I made sure to put myself between the girls and her. "I see that you haven't changed much."

Nightmare Moon: "Hisssss, and you are just as irritating after all these years."

RD: "Wha- How is he over there and over here at the same time!?"

Twilight: "Magical clone, let's leave it as that, I'm still learning that spell."

At that moment, princess moon butt decided to be a bit cheeky and throw my clone at me as a distraction, but she clearly forgot that this was me she was up against. "CHOMP!" I just ate him in one bite. "(Chew chew, gulp!) Girls, get inside, Now!" I casted a spell to open the stone doors.

Twilight: "Don't have to tell us twice!" She and the rest of the girls made their way inside, leaving me and Nightmare Moon alone with me blocking the way as I sealed the doors back up.

Nightmare Moon: "You're a fool to think that those puny cobblestone portae are enough to stop me!" She says with determined certainty.

"Nah, I don't think that, it's just enough to slow you down long enough for the purple unicorn to figure it out while I have my fun." I couldn't help but smirk as I say it.

Nightmare Moon: "Again with that smug irritating tone! GRRRRFSHSSSSHHHH! I am going to enjoy wiping that smug look off that jelly jawline!"

"HEY! That is racist!!" We both charged at each other in our smokey forms and collided while shaking the castle, she had practice I'll admit and I was out of practice and a bit drained doing a lot of defending against the onslaught she against the castle so it was a bit difficult to fight. Now I know that it's not exactly manly or gentlemanly to be bashing on a girl but you gotta understand that the fight wasn't a matter of honor or anything like that, firstly it was a fight of survival on my part and secondly these hooves/hands/paws/slime stubs are rated E for everyone and everypony! BAM! BASH! POW! "Mmff! you haven't lost your edge."

Nightmare Moon: "And you are quite lacking for a demon lord. I have to say, I am quite disappointed."

"Give me a break I was asleep for the past thousand years-" BAMF! "OOF!" I got slammed through the doors by one of her force spells. Warning! Your current form has sustained significant damage! Recommend immediate transformation! "Errrfff, not yet." I looked behind me and Twilight was doing her best to reawaken the elements but they didn't wake up yet.

Twilight: Come on, I don't get it, it should reawaken by now!

Nightmare Moon: She slithers in and smashed the round stones without hesitation. "Ha! Now nothing will stand in my way, not the pathetic demon lord, not the elements of harmony, not even some studious purple unicorn and her gaggle of friends! The night, will last, FOREVER! HAHAHAHAHA!"

Everypony was a silent and trembling in fear for a second, except for me and Twilight as I saw her eyes sparkle with an idea. "... Heheheheh, heheheheheheheh. You really don't get it do you?"

Nightmare Moon: "What? What are you saying? I beaten you, I destroyed the elements!" She says in disbelief.

"You cant destroy a concept, you may have stomped on the temporary vessels but you can't actually destroy the idea itself. Isn't that right, Twilight Sparkle?"

Twilight: "You're right, everything that me and my friends went through has been a test! Oh how I love tests!"

Nightmare Moon: "What are you on about!? You seriously can't think some bucking rocks aren't the elements!"

Twilight: "True and untrue at the same time. The are conduits for the wielders, the true spirits of the elements of harmony are right here!" The energy in the air buzzed to life and the broken stone pieces started to float to their respective pony representative.

Nightmare moon: "No, no this isn't fair! THIS CANNOT BE!" She cries in despair before she gets blasted with with the full force of the rainbow of friendship. "NOOOOOOOOOOOOOAAAAAAAAAAAAAAAAAAHHHHHH!!!!!!" I kept out of the way because I didn't want to know what that blast would do to me and I probably didn't want to know. Course I spotted some dark splotch ejecting out of the vortex of rainbows so I intercepted it.

"Oh no you dont!" I stomped on the tail of it and absorbed the snot of darkness. Hey sage, snack time! Oooh, time to feast and analyze! After that little interruption, I watched as the explosion of colors die down, leaving Luna in her original form. "Princess..." I got to her first and gently woke her up. "Princess Luna."

Luna: Mmm, wha... Jack Inferknight? Where is this, what... Oh no, we did something terrible didn't we?

"Nothing aside of trying to thrust the world into darkness, the usual teen edgelord stuff." I say with a little tease which made her blush.

Luna: "Oh, ye are a terrible red blob." She says while looking away, a purple blush evident on her face.

"Hmhmhm, I try." I say as I help her to her feet.

RD: "Uhh, can someone explain to me what the hay is going on here!?" She says to interrupt the mood before a familiar voice rings out.

Celestia: "I can answer that." The sun rises before the rays shone and she steps out of the blinding light. "Sister!" She and Luna rushed to each other and glomped into a hug.

Luna: "Sister! (Sniffles) W-We're so sorry, we didn't mean for any of this to happen!"

Celestia: "It's alright my sister, I forgive you." She says in a reassuring voice before turning to the girls. "Luna, you see, was possessed by an inner darkness. I only wished I had paid closer attention to prevent this."

"I told you Celestia, not anyone's fault, so don't be blaming yourself."

AJ: "So we just performed an exorcism on a nasty spirit possessin her?"

Twi: Basically yeah.

Rarity: (Le Gasp!) My tail has returned! Oh thank goodness!

Pinky: Hey, you know what this calls for!? A PARTYYYYY! *Everyone was in a solid agreement on that part.*

Celestia: Oh, before any of that. Jack, someone wants to see you.

"Huh? Who would want to see me at this time?" I asked, a bit confused until something small came out of her mane. "Wait, is that- ?"

Mini jack, now Jack Jr.: Hello papa, mama knew you'd be back."

Everypony: Papa!?

"W-What!? ME!?" I look to Celestia who had an innocent blushing smile but I knew she was being mischievous under that. "C-Celest! You're giving ponies the wrong idea!

Celestia: She dramatically feigned innocence with a hoof to her horn. "Why demon lord, does sharing a wine and a bed that night not mean anything when you whispered all those sweet nothings in my ear? Or when you struck my rear to rouse me from my sleep in the morning?"

Oh you coniving little pony! I looked to the girls and thankfully half of them didn't quite know what she meant (RD, Pinky, and Fluttershy), unfortunately, the other half knew quite well and was staring with shock disbelief and was sporting contrasting blushes of their own. "Uh, It's not what it looks like(?)."

Rarity: "O-Oh my!" She was appalled and yet a bit aroused at the information she processed.

Twi: "H-H-He did WHAT!? A-And he... You...!?" Her brain must he thinking up a thousand questions that her mouth can't spit out fast enough.

AJ: "Mister, we need ta have a talk later about treating ladies like that." She looks like she wants to hogtie me to a poll, and I'll admit, I don't blame her a single bit.

Oh boy is that conversation going to be interesting. Gotta skedaddle, took too long to write this.

Author's Note

Man this has not been my year. Also I decided to change up the style of writing a bit.

Appljack: So it'll be more like this right?

Yeah, kinda. Also I'll just leave mine like this. If I can't find the color or if it blends too much into dark mode, I'll leave it as regular too. Oh and happy Hearth's Warming Eve.🎄 Consider this a late year round present.
