Rarity was working away on some clothing as usual. This time, instead of the usual clothing for ponies, she was working on clothing for humans. Unlike most ponies who saw humans with suspicion, Rarity admired the humans for their sense of taste in the arts. Fashion included. As such, she incorporates said ideas with her own, creating a new line of clothing, which turn out to be a commercial success.
Rarity's train of thought was interrupted with a knock on the door. It was most likely another guest, for Rarity. She quickly put away her tools of the trade and went towards the front door.
"Customers?" Rarity thought.
Rarity approached the door, and opened it with her magic. It was Fluttershy. She walked in, with her usual shy gait. Rarity was delighted to see Fluttershy come back from her vacation.
"Darling! It's so good to see you again! How was your trip?" said Rarity.
"um...okay..." Fluttershy said.
"Do tell all about your trip! I'd love to hear all about your trip to Cloudsdale!" Rarity said, enthusiastically.
"Well...it's about that..." Fluttershy said.
"Oh? What's the matter, dear?" Rarity said, a bit more worrisome in tone.
"Well I-" Fluttershy said, before being interrupted.
The door was slammed open. Twilight and Pinkie Pie quickly rushed inside, and closed the door. Rarity and Fluttershy looked at the two in utter confusion.
"Ugh! Have you not heard of knocking?! At least Fluttershy took the time to knock!" Rarity said in outrage, commenting on the lack of proper behaviour.
"Rarity you gotta hide us!" Twilight said. "There's a madman after us!"
"Why, whatever do you mean, darling?" Rarity said, still utterly confused.
"A human with a pistol!" Pinkie Pie said. The chase seemed to have curled up her hair in ways only Pinkie Pie could understand.
"Now settle down, dearies. Let's at least try to settle down and then we can try to find out what's going on." Rarity said, trying to get everypony to recollect themselves before going any further.
Rarity proceeded to go about with her work. Meanwhile Fluttershy attempted to stop Rarity to tell her about something in Fluttershy's mind, but was unable to. She just simply stood next to her. On the other side of the boutique, Twilight and Pinkie Pie were murmuring.
"I don't even understand. Why were you working with him?" Twilight said.
"I...I didn't have much of a choice! He just came up to me and said 'RAWR! WORK WITH ME OR ELSE' and he pointed that thingy which looks like a miniature cannon, because apparently I saw a box filled with something, and it was that! He told me to pretend to know nothing, stay in the Everfree forest, and stand guard. He basically told me not to tell anypony!" Pinkie Pie blabbered in panic.
"Wait, does that mean he killed the two children?" Twilight said.
"I think he did! I mean come on! It's pretty obvious! He is a madman! All the humans are crazy! I mean, look!" Pinkie Pie said, she then tossed out the two corpses from before.
"PINKIE! WHY DID YOU BRING THOSE HERE?!" Twilight said in shock.
Rarity, growing tired of the incessant loud noise, went up to Twilight and Pinkie Pie to lecture them about noise.
"Twilight, Pinkie Pie, what on Equestria is goi-AUGHGHHGHWHGH!" Rarity said. She saw the two corpses lying on her recently cleaned floor.
"PINKIE! WHATEVER SHALL I DO! I JUST CLEANED THIS FLOOR!" Rarity said in shock, completely unaware of the fact that it's corpses dirtying the floor.
"RARITY! THERE ARE BUCKING CORPSES HERE!" Twilight said, with a facehoof.
"Oh my..." Rarity said.
Fluttershy was next to see what the fuss was about. She saw the corpses on the floor. She was paralyzed with fear. But her fear was slightly different.
Fluttershy quickly ran out the door.
"Fluttershy!" Rarity said, calling out to Fluttershy. She then turned to Twilight and Pinkie Pie.
"How rude...first you dirty the floor with rotting flesh and now you scared Fluttershy away." Rarity lectured. She simply returned to her work.
Twilight simply watched as Rarity just went back to her work. Meanwhile, Pinkie Pie was playing with the corpses in a rather...peculiar way. Pinkie Pie proceeded to smush the two corpses together, as her face began to show signs of insanity. Her mane also began to straighten.
"Pinkie! What are you doing?!" Twilight said, in shock.
"Hey! These pieces fit!" Pinkie Pie said, with a slight sense of insanity in her.
This was it. All those years of partying, breaking the fourth wall and physics. It had finally gotten to her head. She had now gone crazy. Pinkie Pie needs medication, FAST. As Pinkie Pie continued to play with the corpses in a playfully insane manner, a thought suddenly passed Twilight.
"Wait...Pinkie...I just realized..." Twilight said. She then took a closer look at the foal half of the corpse. It was barely recognizeable, but it was definitely a shade of yellow. The tail, however was black. It was unusually long for a foal. That was, of course, if the foal's parents originally had longer tails.
Just then, Twilight had remembered something.
