The Great Machination

“You…You ruined my wonderful dream” said Lightning Dust to herself with hateful spite.
Staring at the biggest poster in her room, a Wonderbolts poster, shedding one last tear, she continued on contemplating. A scheme to get back at a former friend for her own suffering.

“You boast that you’re the best flier in all of Equestria, well that will change soon, just like how you demoralized me and stripped me of all my confidence, dignity and happiness, the same will happen to you.” Said Lightning Dust with the slightest tears.
She vowed terrible revenge, and would stop at nothing to execute her plan. After being kicked out of the Wonderbolts academy for the incident, she finally, after a long time of solitude and misery, began to gather everything needed for the plan.

“You took something away from me Rainbow… now I’ll take something really precious to you…and I know exactly the way to do it ” snickered Dust malevolently.

“You might not lose something that is yours, but it will hurt you far more than if I did” Smiled Dust.
Lightning Dust set out to seek a friend she knows from long ago. A pony specialized in black magic and alchemy. Arriving at a village not far from Cloudsdale, Lightning Dust enters a shady, old black shed.
There she finds a light green unicorn in the middle of the room fixing up a potion brewed from a large black cauldron.

“Lightning Dust! What brings you here old friend” happily said Glinda.

“I need a special favor from you… can you still brew a potion that will increase anger moods?” questioned Dust.

“An aggression potion? What for?” asked Glinda.

“I have a great plan and it involves a set up… but I don't think her friends would punish her hard enough” sneered Dust.

“What do you have in mind Dust and who exactly?” questioned the lost pony.

“Remember when I left to the Wonderbolts academy.” said Dust.

“Well Rainbow Dash stole and snatched my only dream away from my hooves… and got kicked out because of her, told never to comeback by the Wonderbolts team leader Spitfire.” disappointingly said Dust.

“So I plan to hurt a friend she holds most dear and it will leave a significant scar on her…Pinkie Pie” said Dust.

"Plus i bought all the colors of manespray i can get my hooves on" added Dust

“I will use the manespray to cover my coat, mane, tail, buy me some magenta contacts, make me a waterproof cutie mark sticker and ill look exactly like Rainbow Dash.” confidently said Dust.

“Don’t you think you’re taking this a little too fa-““NO IM NOT!!!” screamed dust but then regretted it.

“Sorry Glinda… I didn't mean to scream at you, just I'm very up-set.” apologetically said Dust.

“It’s ok but think this through…Pinkie Pie did nothing to you and everybody practically likes her presence…and if you get caught in the act, who knows what punishment you’ll be facing” worriedly said Glinda.

“Don’t worry about it” said Dust.

“Don’t say i didn’t warn you Dust… very well, I will brew you an aggression potion… now keep in mind, this stuff is very powerfu-.”,

“I get it Glinda” interrupted Dust. “One drop of this stuff is enough to provoke even the most docile of ponies… this will intensify mood swings, anger episodes, and-“

“Just please Glinda, I'm really excited for this” interrupted Dust.

“Fine…Ill be right back” said Glinda.

“Oh boy, I can’t wait to see the tears that will fall out of her eyes when I'm done with it…that’ll teach ya not to mess with Lighting Dust!” snickered Dust.
5 minutes later,

“Here” giving a triangle shaped flask of blood red liquid to Lightning Dust and then putting it in a satchel she brought. “How do i apply this?” asked Lightning Dust.

“You add a drop into their food or beverage, it will take a couple of hours to kick in…but again be careful this stuff can make anypony dangerous.” explained Glinda.

“Just one drop… anymore and it can cause dangerous mood swings” said Glinda with serious demeanor.

“Thanks Glinda, you’re the best a pony could have.” said Dust.

“Aww… Thanks Lightning, no problem, are you absolutely sure your gonna do this? Is this really worth it?” worriedly said Glinda.

“I wanted to become a Wonderbolt my whole life since I was a little filly, you think after what she has caused, the humiliation, the pain and suffering I went through a long time, knowing I can never be a Wonderbolt ever again in my life, I will forgive her?” lightly scolded Dust.

“You have to understand my suffering Glinda; would you forgive someone that took the only thing that defined you? Huh?! I sure wouldn’t and she will regret ever doing that to me, I'm going to end this terrible misery once and for all, why did it have to be me!!” Dust broke in tears again

“I understand, and I wouldn't either, just make sure you to follow what your conscious says, if your conscious says its right, that’s you but be aware that not all decisions are rational” Sincerely said Glinda.

“Look after yourself Lightning, be careful what you do Lightning Dust, because that mistake might travel with you for the rest of your life.” said Glinda.

“I know Glinda, I got ya!” said Dust

“Make sure to heed my warnings Lightning! That is potion is not a toy, you can put your life in danger” worriedly said Glinda

“Sure thing, Glinda, thanks again, we’ll be seeing each other soon” said Dust with a smile leaving the shed.

“Ill befriend the Mane 6, and find out where they’re going today… that’s when ill put my plan in action” brainstormed Dust.

“ With this potion, ill have Rainbow Dash suffer at the hands of her own friends…I've waited for this for a very long agonizing 2 weeks,” Dust giving a wicked grin

“Where’s a good to start looking for them? Hmm… ah! Let’s try Sugarcube corner, I'm sure they’re having a party like usual.” snickered Dust.

“Time to ruin her life” said Dust with malicious demeanor.
