The window proved to be an adequate observatory for agents double o Dash and Scootaloo.  The architects settled it at just the right angle to create a viewing platform to see within the confides of the Carousel Boutique from their perfectly settled perch, which was the inside of a bush.  There, the two pegasi observed the next target on their pranking spree.  As a folder fell open on the dirt, the two cunning ponies briefed their unsuspecting target.

Pony: Rarity, the Element of Generosity

Sex: Female

Race: Unicorn

Colors: White coat, indigo mane, azure eyes

Cutie Mark: Three diamonds

Occupation: Tailor / fashion designer

Notes: Overzealous about her dresses, fashion, appearance, and anything to do with Canterlot or the Royal Family.  Tends to overreact over the smallest things.  Not keen on getting dirty.  Will at times use deception and sex appeal to get what she wants.

"Hold on what?"  Scootaloo asked, clearly confused.  "What does that mean?"

Dash snorted.  "Basically she's a MIL--"  She cut herself off as she took note of who her partner was; more specifically her age.  "MIL...mill!  She's a mill!"

Scootaloo's head tilted.  "Mill?  Huh?"

Dash tapped her hooves together, scrambling her mind to come up with a viable excuse.  "Mill, as in...her dresses!  She makes so many dresses a day that she's like a mill...of dress making!  Yeah see look!"  Dash pointed to the window to cause a distraction, hoping that her obvious anxiety would go unnoticed by the little one.  Fortunetly it worked, and an orange head swiveled around until her eyes met the plane of glass.  From there, she noticed the azure aura cradling a multitude of fabrics, needles, threads, measuring devices, and feather.  

"Oh yeah."  Scootaloo said, oblivious to Dash's over-exaggerated sigh of relief.  "I guess that makes sense."  She paused.  "But what does that have to do with se-"

"Illumarenati."  Dash replied, expertly cutting her off before any more was said.  "As you can see, Rarity has already made six dresses.  Six times two, two every ten minutes, twelve.  Sixty seconds in a minute, sixty times ten minutes, six-hundred.  Twelve times three, three pairs of dresses in ten minutes, thirty-six.  Thirty-six plus six-hundred, six-hundred and thirty-six.  Twenty-one, Rarity's age, plus nine, Sweetie Belle's age, thirty.  Thirty plus six-hundred thirty-six, six, six, six, Hades, Illumarenati."

Scootaloo gasped.  "New world order!"  She shouted.  "The revolution is upon us!  Rarity will become the Tyrant Queen of Equestria and rename it Rarestria, and we'll all be forced to mine diamonds for her while wearing fabulous dresses, and if we get dirt on them it's off with our manes!"

Dash clapped both her hooves to Scootaloo's cheek.  "Get a hold of yourself!"  She shook her companion vigorously, "I'll make sure that doesn't happen!  All we need to do is prank Rarity, and the balance of the universe will be preserved, and still under the dominance of our lord and savior Snowflake."

"Praise be."  Scootaloo recited, then turned back to the window to continue their reconnaissance.

Using Scootaloo's innocence, combined with their over-zealous imagination, to recollect herself, Rainbow Dash scooped up the file and disposed of it expertly.  Once the inquisitive eyes of the filly returned to her, Dash offered a shrug and opted to continue on with the operation unhindered.  From their position, Rarity was observed with expert prowess while she stitched, sewed, whined, or brainstormed.  

Scootaloo stared mindlessly through the window, trying to come up with a plan of her own to impress her idol.  She thought of trivial things, like invisible ink on fabric, but none seemed to catch her attention.  "So what's the plan?"  Scootaloo asked.  

Dash did not answer immediately.  While true her primary focus is to prank Rarity, and usually when Dash sets her mind on something she goes into a tunnel vision and pays no heed to the world around her, but a spark of attention was bitten off and left to the filly before her.  She didn't exactly pay attention to what her companion said, but she knew something was uttered.  After a moment of silence, she asked, "Huh?  What was that?"

Scootaloo blinked.  "I said 'what's the plan?'"  Ever inquisitive as she was, the orange filly could not resist to satiate her curiosity.  "Is there something wrong, Dash?  You've been in and out all day."

Dash mentally sighed.  She knew Scootaloo would eventually catch on, but it never occurred to her how quick.  She was a smart filly, smarter than many give her credit for.  She just needs to unlock that potential; mainly in literature.  Both her parents and Cheerilee can see in her writing assignments that there is a spark of imagination there, but it seems as if she represses it.  Though Her vocabulary, try as she may to understand bigger words for her age, could use some improving, she is still, in more ways than one, an intelligent filly.

Dash looked back to Scootaloo.  She didn't want to say anything about the 'visions', as she called them, in fear of worrying the child over her mental state.  State of mind may be an issue, but there is still one excuse that still has a dominance over the brain's health, but in a more blunt way.  "Yeah I know I've been out of it a lil bit.  It's what happens when I do to many sonic rainbooms at once. The pressure is too much on my head and makes me woozy."  It wasn't a complete lie, air resistance at that velocity to an unprepared pegasus will cause light headed-ness, it's just that Dash is more hardened and could sustain a bit more G-force than other pegasi, excluding the Wonderbolts and the military...and Snowflake.

Scootaloo looked up into the eyes of her honorary big sister.  Her peircing gaze softened and her ears flattened.  "Will you be ok?"  She asked.

With a wave of her hoof and an utter of a 'pssh', Dash said.  "I'll be fine.  It's not like it's the first time it's happened."  Yet another half lie, but it will have to suit for a viable excuse.  Luckily Scootaloo believed it.  "Anyway, the plan!  What we're gonna do is...something that I will soon think of!"

Scootaloo's smile wavered.  "You didn't have a plan beforehoof?"

Dash smiled proudly as if she had just been given a reward.  "Nope!  All my best ideas are usually made up on the spot."  Her hooves clapped together.  "Now...let's see here."  Her gaze shifted to the window again, observing the white unicorn in her natural habitat.  She racked her mind, brainstorming cleaver and devious plans to either humiliate, or backtrack her friend on her daily work.  Breaking line of sight with Rarity, she turned to Scootaloo.  "C'mon now laddy, I need ya best ideas.  Chop chop!"

"Uhhh..."  She looked to the window.  "Maybe we could..."  The filly began to mumble aloud as she thought.  "Invisible ink?  No...too cliche...same with a fake mouse...something to do with...no maybe...no..."  She turned to Dash, eyes glued to the floor.  "I got nothing."

"Drat!"  Dash exclaimed.  There have been many times where the speedster pegasus would be completely stuck on trying to form a decent prank.  It's like writers block to her.  It came in and blocked off her thinking processes like a wall.  She rubbed her temples in attempt to come up with something.  "Uhhg...where's Sweetie Belle?"  She asked.  "I might have an idea...maybe."

Scootaloo tilted her head towards the window.  "In there."

"Could you get her?"

"Whatcha need, Rainbow Dash?!"

The pegasus yelped and nearly tumbled out of the bush she was hiding in with her companion.  Swiveling her head around to sniff out the culprit of the surprise attack, she only found the smaller of the two white unicorns staring at her excitingly.  Brushing herself off, Dash stood back up, and attempted to retain what dignity she had left.  "I uh...there was a spider on my hoof."  Success!  No matter how much bravado one can have stockpiled, the ol' spider-on-the-hoof always wins them over.  Let's face it, everyone hates spiders...except for Snowflake.  "Anyway."  Dash continued.  "Where did you come from?"  

Sweetie Belle smiled knowingly.  "Cutie Mark Crusaders always know when they're needed!"

"You got that right!"  Scootaloo added, bumping hooves with her friend.

The migraine can wait.  Dash thought.  Attempting to figure out the logic behind anything in this Faust-forsaken town is near impossible.  During the Era of Discord, question him, and you get turned into a potted plant.  During the Era of the Pink One, question her, and you end up with a migraine that's only curable by immediate ritualistic brain surgery.

Dash shook off her lingering thoughts to focus on the task at hoof.  "Alright Sweetie Belle.  Scoots and I here are pranking your sister.  Now, you wouldn't happen to know when Rarity's next shipment of supplies for the Boutique is?"

Sweetie Belle bobbed her head up and down.  "Yeah...uh, tomorrow."

"When?"

"Sometime around 10am."

Dash smiled.  "Bene."  She replied, then turned to face her back to the two fillies.

"Oooohhh."  Scootaloo gaped.  "Whatcha got planned, Dash?  Are we gonna switch out the boxes so she gets something really weird instead of what she was expecting?"

Dash half turned her head to reply.  "Possibly."

"Oooh!  Oooh!  We could put snakes or something gross that Rarity really hates to freak her out!"  Sweetie Belle suggested.

From behind her, the two fillies could hear Dash mumbling to herself.  The plan seemed solid enough, but it lacked the finesse that all of Dash's pranks had.  Sure she could put harmless snakes in the shipment to give Rarity a good scare, but there needs to be more than just a scare.  There needs to be some subtle meaning to it.  She needed more details on the shipment.

Turning back to face them, Dash asked to Sweetie Belle, "Do you know what's in the package?"

Sweetie Belle stopped for a second to recall what Rarity ordered.  "Uhh...I think it's...silk?  Maybe?  Yeah I think it's silk."

The peices then started floating together.  "Silk."  Dash repeated.  "Silk...yes, this will work nicely."  There was the connection that needed to be made to complete the prank.  Oh it was genius, subtle, and totally worth the laugh.  There was only one problem though, and that thought made Dash deflate a little.  "Where in Equestria am I going to get silkworms before tomorrow?"  She mumbled to herself.  Silkworms were not easy to come by.  Even though they are a domesticated creature, and can be raised under certain conditions almost anywhere, Dash couldn't think of anyplace near Ponyville that raises and produces silkworms.  There was, however, one option available.  It's a long shot, but it's the only shot she has.

"Sweetie Belle."  Dash said, turning to the filly.  "Do you know where the package is coming from?"

"Rarity gets all her supplies from Canterlot."  She replied.

And the plan was set in motion.  Dash smiled, it was going to work.  She'll make sure that it does work.  "Alright I got a plan."  At the mention of that phrase, the fillies huddled together close to listen.  "We'll have to wake up early tomorrow morning to execute it alright Scoots?"  The filly in question groaned, but nodded.  "I'm going to fly to Canterlot and pick up some silkworms from a silk farm, then intercept the package during its travel to Ponyville, sabotage it with replacing the silk cloth with the silk worms, disguise myself as a mailpony, arrive to Rarity's door and deliver the package, ???, profit!  Capisce?"

Both fillies exchanged confused glances.  While it is true that Rainbow Dash is awesome, and the fastest flier in Equestria, and the only pony that can perform a sonic rainboom on command, Scootaloo nor Sweetie Belle never thought that the prismatic pegasus would go through such lengths for a simple prank.  By train, Canterlot was an overnight travel.  By air, nearly a full day.  Take note that that statistic applies to normal pegasi.  By Dash's standards at her self proclaimed 'normal' flight speed, it would probably be a five to six hour flight.

Still, it was an extreme just to have a laugh and an irritated Rarity.

Fortunetly for the fillies, they didn't need to present the facts to Dash.  The realization dawned on her all by itself.  "Oh who am I kidding?"  Dash exhaled in defeat.  "I'm too lazy.  I don't want to fly all the way to Canterlot, pick up some stupid worms, then fly all the way back in under a day!"  She snorted.  "Screw it.  I'mma just put food coloring in her shampoo again."

Violet light surrounded a kettle as hot tea poured into a small, decorative cup.  How many has this been?  Fourth?  Fifth cup?  Dash had lost count.  She hadn't noticed when her nervous fidgeting finally stop.  For it had been a little over an hour since she arrived at Twilight's abode.  Probably when she finished the first cup of tea, she figured.  Tea seemed to always have that effect on ponies.  

A phantom of a smile crossed Dash's lips.  It was the second time she almost smiled since yesterday, and the first that her magical friend detected tonight.  Hopefully there will be more, and not just phantoms of smiles, but genuine smiles.  The story had not gotten far, but Twilight could tell the roots of her sorrow run deeper than she can imagine.  She had been racked with a combination of guilt and depression for long enough.  It was time that changed.

"Then what happened?"  Twilight asked.

As always, Dash took a second to calm her nerves before answering.  After a sip of tea, she said softly, "Rarity got pissed the next morning."

Twilight risked a chuckle.  "No I mean, your day with Scootaloo."

Dash stared into the half empty tea cup.  The liquid rippled as a fresh tear fell into it.  "Well...we went to prank Pinkie after that."
