Rarity decided to pull out all the stops to finally show everypony that the Carousel Boutique was superior to the Scary Boutique

The first thing she did was get the front of her store covered in banners announcing her Nightmare night line. Complete with mannequins dressed in some of her nightmare night costumes set outside the store.

Once she had all ready she prepare to call for attention.

RUMBLE!!!

Only for a big storm cloud to appear over her boutique and rain on her.

Causing her to scream out and yell in despair while trying to save what wares she brought outside while screaming out if this was one of Dash's nightmare night pranks it wasn't funny!

Only for Derpy to fly down with an apologize face as she was carrying a bag with the Spooky boutique logo on it..and with a hole on the bottom.

Hole from where a can label "INSTANT STORM: GET YOUR PERSONAL SPOOKY RAIN CLOUD" fell off and opened just over the boutique.

And needless to say she took this with the grace of a lady.....by snatching the bag and stomping on it while shouting out angrily.

(Next)

Rainbow Dash was napping on a cloud when suddenly her tail was pulled down by a blue aura.

The pegasus grunted as she found herself holding a BIG sign that said VISIT CAROUSEL BOUTIQUE and apparently she now had to juggle it and call the attention of others.

With her giving a grumble about Rarity owing her big time for this as she played advertising, not noticing the words on the sign changing after being hit with a small zap of magic that came from a near by alley way.

Ponies noticed Rainbow making tricks in the air calling their attention..then reading the words...

Rarity was sure this will work as the ponies look interested...only for them to walk away her boutique instead of in.

Naturally this shocked and confused her but when she looked up toward Rainbow Dash her eyes widen in horror seeing the sign advertising the scary boutique!

The next thing Rainbow knew, was the sign being torn from her and then ripped into pieces by an enraged Rarity making the best impression of a rabid wolf ever.

All while Dash just stared silently wide eyed at the sight before trying to leave as quietly as possible.

(Next)

Rarity tried a more...loud approach.

She got from Pinkie a microphone and some speakers; ready to use her voice to announce her sales to the four winds.

She even managed to get Vinyl Scratch´s aid with the speakers.

So she set all, did some vocalization, took water, more vocalization, coughed..then she felt ready to talk.

BOOM!

BAM!!

BANG!!

When loud explosions and fireworks began igniting in the sky.

Causing Rarity pause and look up at the sky confused before putting on an expression of horror.

The fireworks exploded in the shape of spiders, laughing skeletons, jack lanterns, monstrous faces.

But the ugliest one was a big one that didnt seem to dissipate, forming the face of that DISGUSTING UNICORN

"COME IN! COME IN! DONT BE LATE" it called, his voice echoing all over Ponyville " THE BEST COSTUMES, TREATS AND DECORATIONS FOR A SCARY-FUN NIGHTMARE NIGHT ONLY IN THE SPOOKY BOUTIQUE!!!"

Needless to say...

A scene of Rarity exploding in rage as she started to punch, kick, and stomp on the speakers while Pinkie Pie and Vinyl watched on shocked

...She did not take this well.

THAT DOES IT!!!

She was going there and give that mare and her hideous minion a piece of her mind!!!

And with that she stomped off taking no heed of the surrounding ponies watching her in shock and wariness.

(Meanwhile)

Certain purple Alicorn was able to hear and see all the show from the other side of town

"Well thats quite an impressive spell" said Twilight admiring the announcing head "although bit noisy, hope they had a permit to do so or they could have troubles with the mayor" she added.

ACHOOO!

"COCK A DOODLE DOOOOOOOO!"

Before jumping out when a giant rooster spring into existence behind her letting out a cry.

Next to her was Discord, covered in bandages, anti-rash cream, and a pair of mittens that Fluttershy forced him to wear so he stop scratching himself.

"Uhh...Discord you doing okay?" Twilight asked as she was actually starting to get worried for the spirit of chaos he was beginning to look far worse than he did when he pretended to be sick to trick her and Cadence.

"Snort!! no" he called as his body shivered (actual icycles forming on him) "it got worst suddenly ACHOO!!" a tree began tap-dancing away.

"You mean just now...when those fireworks went off?" Twilight asked with a blink before frowning thoughtfully.

"Ugg yes" he snorted again.

Twilight narrowed her eyes...could it be? Rarity might have some reason outside her weird jealousy attack or could this be a coincidence?

After all the trouble started after the Scary Boutique moved into Ponyville which itself could be a coincidence...but the timing...plus Discord allergic reaction just now....made it suspicious to say the least

"Ummm maybe should take a look just to be sure" she said "Lydia seems like a nice mare so maybe this is all just a coincidence or a misunderstanding"

"Urg...didn't Fluttershy...say the same...thing...about that Starlight pony...running a cult?" Discord asked sending her a slight look having heard of that particular escapade from his friend.

Twilight stiffed.

"yes...and we end up investigating and finding the true" she coughed "so I should do the same here" she said "Best case scenario this sets Rarity mind at ease....worst case she'll be holding it over my head that she was right for Celestia knows how long." Twilight added with a sigh.

"Ugg if its help my issue Im fine with both" said Discord "lets..ACHOO!!!!" the ground turned to liquid chocolate and Twilight sunk on it.

"Grrrrr" she glared at the chaos spirit now covered in chocolate "why dont you...wait back at Fluttershy´s?"

"What?!" Discord however at that suggestion gave her affronted look, "Are you implying I can't handle a little allergy or the poser causing it?!"

She raised an eyebrow in a "you serious?" manner.

"Grr i'll have you know even in my current condition i'm still the big cheese of chaos magic..." Discord remarked giving her a annoyed looked, "and I can easily handle the trouble maker causing mischief on MY turf with a one arm, tail, and leg tied behind my back! Achoo!!!

And literal one arm, tail and leg became like rubber tying him down

"Uggg just...keep yourself hidden and quiet..let me do the talking" grunted Twilight knowing arguing with Discord was pointless.

So with a tired sigh she head off to the scary boutique honestly feeling exhausted at this point and just wanting to get to the bottom of things

(not long after)

The Alicorn entered the store; quickly finding Lydia helping no other that Silver spoon on a...Windigo costume?

"Oh princess Twilight hello" the pale mare greeted after finishing putting some make up on the filly which seems to activate the magic of the costume making the filly turn ghostly with an ice tone and her hind legs into a ghostly tail leaving a small snowflake trail behind her.

"Once again impressive..." Twilight said with a slight smile before frowning remembering Windigo...instincts and habits, "though...these costumes don't come with any side effects do they?" she asked looking to Silver Spoon.

"Well Im feeling a bit chilly" said the filly with a giggle

"Hehehe dont worry princess" said Lydia "they only give physical traits and maybe light versions of their abilities but no real powers, insticts or similars" explained the mare "I make sure to check each costumes before putting them on sale" she giggled "BJ sometimes say i risk turning a rule-lover but i prefer to think im making sure anypony that buys one of my costumes have a scary yet fun experience"

"Hmm BJ?" Twilight asked sending Lydia a curious look already having a guess who she was referring too.

"Oh right...umm..you did say you wanted to meet him right?" asked Lydia a bit nervous.

"That's right like I said your enchantments are impressive work of magic, and i'd love to trade notes with the caster." Twilight explained leaving out she had now other reasons for wanting to talk to Lydia business partner.

"well...i suppose...sigh..ok..." said Lydia before calling to the air "BJ?"

FLASH!!

"Hey babes you called?" the unicorn Rarity met teleported in front of Lydia; jolting Twilight "how is the wind-pony-thing costume working?" another flash and he appeared next to Silver spoon "really cool if say so myself" he chuckled at his pun "let me tell you kid, you certainly will give the term giving a cold shoulder a new meaning" he patted the filly...only to have his entire leg covered in ice...he blinked "see what i mean?"

Another flash and he appeared in front of Twilight

"And who we have here?" he asked with mischief in his tone "Babe! you didnt tell me we will have royalty visiting" another flash and his outfit changed to a noble like suit...filled with holes and clearly dirty "i would put on my best suit" he gave an exaggerated bow at Twilight "your highness...i put myself at your...hooves?" he blinked "umm now that i think about it" he turned to the audience "being fascinated by them would count as hand fetish or foot fetish?"

"BJ behave~" Lydia said back with a giggle while Twilight blinked at the introduction this pony reminded her of....Discord.

Which caused her eyes to narrow in suspicion her personality and the way he was using his magic it hit all too close to home....was Rarity actually right?

"Hey Im being an angel right now babes" said BJ..actually gaining white wings and a toga? "and considering you have been working on that special project for her im being quite respectful"

"BJ! that's meant to be a surprise!" Lydia said with a hiss while Twilight frowned arching a brow.

"Special project? What special project?" she asked a note of concern entering her voice.

"What else? a special costume she expended all our first day and night here designing and making, only for you to not take a time to try it" huffed the unicorn with some anger "and she has been really excited about presenting it to you"

"Wow...that's really thoughtful of you Lydia.." Twilight said genuinely while sending Lydia a look of gratitude "but you know there was no reason to go through any trouble on my account.." she added with a concerned look "I would have been happy with any of your costumes."

"I..well.." Lydia looked embarrassed as she received payment from Silver spoon; who then floated giggling out the store passing by and scaring an approaching angry Rarity "I just...its the first time Im..well..having someone like you as client and..well wanted to offer you something special" said the young mare with sincerity

"Huff and i keep telling you anyone that think what you do isnt special is because they have trash in their heads" said BJ

Outside Rarity recover from the fright..only for a trashcan to appear on mid air and empty its content on her.

"I know but I really wanted this to be my best work...I mean how often do you get the chance to design something for royalty!" Lydia exclaimed out with a smile.

Twilight blushed at that.

"I...well...you know..Im not that..special" she said actually a bit touched by the young mare´s words

"Pff no special she said" mocked the unicorn before turning to the audience "said the one holding the lead record of the 34 rules" he winked before returning to the princess "you really must be if Lydia here made such effort as she only do it for the best as she is the best" he said in conviction.

"Ah well thank you.." Twilight said nervously smiling before giving off a confused blink, "34 rules?"

"Sorry we are T-raking at best so cant say more" said the unicorn "instead, since you are here...you wont mind trying the costume right?" he suggested.

Outside Rarity managed finish digging herself out the trash that covered her in time to hear the unicorn proposition.

WHAT?! No no surely Twilight wouldn't...

"well...I mean...since you took the time and effort" said Twilight "I..dont see why not"

NO! HAD EVERYPONY TURNED AGAINST HER!?

" you sure ? " asked Lydia nervous " I mean I dont mind but...I mean if you want "

"I dont see the harm let's see what you've been working on." Twilight said with a encouraging smile.

Lydia smiled

"Ok..BJ bring it please" asked the mare

"Sure thing Babes" and the unicorn disappeared in a flash.

Leaving Twilight alone with Lydia and perhaps giving her a chance at some answers.

"So...your friend seems like the interesting sort." She began with a slight cough.

"Hehehe is a way to say it" answered the pale mare with a smile "we have been friends for quite a time and with all the ups and downs I wouldnt change it for anything"

"I'm glad to hear it friendships something to be held dear after all." Twilight said nodding her head before arching a brow, "so how did you meet?"

"She moved into the old house I used to hang around" said BJ flashing back with a manikin "she was new, needed a friend and we kinda click in the moment" he added with a smile.

Twilight looked at the costume on the manikin.

It was a short, silver semi transparent toga with silver rings for the hooves and a nice necklace; the cloth seems to sparkle and Twilight could tell it was woven with great care and effort.

Although one thing that gave her some doubts, was the headpiece it had, as it was made of at least a dozen fake snakes that she was sure will come alive once she wear it.

"It looks really good.." Twilight said to Lydia while giving her a smile causing the mare to smile in turn "though.." Twilight look nervous at the head ware, "I'm a bit...afraid of snakes.." she admitted with a flush.

"Oh!" Lydia gasped before looking down "I...Im sorry, I didnt know" she said with a sad tone.

"HA! Twilight wouldnt ever wear something with snakes" Rarity couldnt help but gloat; now for sure Twilight will rejected it and come to HER. boutique for sure

BJ didnt seem happy about it.

"Hey babes dont worry" he said trying to lift up the young mare spirit "is just as you say, nothing better to get over your fears than face them" he then give Twilight a..not threatening yet not friendly glare "Its nightmare night so not better way to face your fear right princess?"

"Hmm...I suppose that's true.." Twilight admitted tentatively picking up the headwear with her magic "And none the less I should at least give the costume a try after your hard work." she added with a determined look.

Rarity jaw fell

"You..you mean it princess?" asked Lydia with hopeful tone.

"Of course, just give me a minute and I'll try it on." Twilight told her with a comforting grin while Lydia look overjoyed a feeling that Rarity wasn't anywhere close to the feeling at the moment.

"You..she...OH NO!" the white unicorn declared "not on my watch!" she prepared to march in.

ACHOO!!

when suddenly a Draconequus crashed on her; propelling both away from the boutique via chaotic sneeze.

"You heard something?" asked Lydia as she accompany Twilight to a fitting Room

"I didnt heard anything" said BJ holding a pepper shaker...for some reason

Lydia blinked at that

"What?" asked the unicorn then holding up a sandwich "its lunch time"

Lydia gave him a look that screamed she knew he was up to something but choose to drop it as she focused on helping the princess into her costume while BJ gave a little cackle.

"Uggg DISCORD!" yelled Rarity once she found herself back on land...with certain spirit of chaos over her.

"Urg...sorry about that.." Discord groaned out with a displeased look rubbing at his nose, "this allergic reaction is getting worse.." He admitted with a slight growling groan of annoyance "on some good news, it seems we found the source in that store" added the Draconequus.

"You did?" Rarity asked with a blink before shouting out in triumph, "Ah ha! I knew it! I KNEW IT!" She yelled out with an excited hop "Those ruffians are the source of all of Ponyvilles problems and have been brainwashing ponies into buying their horrible products!"

"snort!! the last part i dont know and dont care ATCHOOO!!" leaves turned into waffles "want I want is them out of here!!"

"I couldn't agree more darling!" Rarity exclaimed out with a wide positively evil smile "I believe time to send these miscreants packing!"

ACHOOO!!

FLASH!!

"Eeeppp!!!"

The next sneeze literal brought Fluttershy into their talk...by falling onto Rarity

"Oh my goodness! Im sorry Ra-DISCORD!!" She called in worry looking at the down spirit, looking all sick, snots coming out like rivers from his nose and overall looking done for "Oh no! oh poor you!" she flew to him and grab his hand "come! lets go back to the cottage, I will prepare you a hot bowl of soup and then to bed with you"

"Urg...as tempting as that arg...sounds...I can't.." Discord said with a low scowl, "not till urg...I get rid...of the source of this...calamity!" He added gesturing toward his body.

"Well you wont be getting rid of anything in your condition!" said the pegasus in an angry mother tone "you coming home right now and try recover first!"

"But...Fluttershy! Ponyville is in danger!" Rarity chimed in a mild desperately and a bit wary on taking on this ruffian without discord helping her.

"Im sure Twilight can handle anything that need to be handle while Discord rest a bit" said the pegasus pushing Discord to move "I never left any critter risk its health and I wont start with him!"

"But...but.." Rarity stammer out watching as Fluttershy practically dragged away Discord...and her salvation "UGGGG!!!" she groaned in frustration "FINE! at least now i know i was right!" she huffed turning around and rushing back to the market "now Twilight WILL HAVE to hear me! and then we can finally stop these fiends from whatever their planning and everypony can shop at MY boutique again!"

With that she rushed back towards the Spooky Boutique ready to finish this.
