(When Rainbow Dash was a filly...)
Rainbow Dash smirked as she looked at the two bullies next to her. They thought that she wouldn't beat them in this race? As if!
"You're going down!" taunted one of them.
"In history, maybe!" retorted Rainbow, shifting to her ready stance.
The many fillies watching cheered loudly as Fluttershy raised the checkered flag into the air. Rainbow took in a quick breath as she stared down the racetrack.
Alright Rainbow, you can do this! Just need to win this race! she thought, Don't worry, Flutters! I'll defend your honor!
Fluttershy lowered the flag, and Rainbow took off as fast as possible. She quickly swirled around corner after corner, even doing an aileron roll at one point. She heard a loud smash, and glanced behind to see that one of the bullies had crashed.
I actually feel a bit bad for him... Well, at least the race is easier now!
Rainbow smiled as she flew through the clear sky, before being knocked to the side by the other bully.
"Later, Rainbow Crash!" he taunted, flying down towards the next ring.
"Hey!" yelled Rainbow angrily.
She quickly regained control, and also started to fly down towards the ring. Rainbow noticed that she had begun to gain speed, and felt her eyes begin to sting. She managed to keep her eyes open when suddenly-
...
(Back in Fluttershy's cottage...)
Rainbow Dash flinched suddenly, before falling on to the ground. Small sparks of blue and pink shimmered around her before dissipating into the air.
"Ouch!" yelled Rainbow angrily, "What just happened?"
"It looks like there's some sort of magic preventing you from telling us," said Twilight, "That's odd. Why would somepony prevent you from talking about when you were younger?"
"Don't know, do care! You're a unicorn, can you try and figure out where the magic's coming from?"
"Hmm... Well, I probably have a book at the library that could help, but I don't know what the spell could be called."
"Maybe in a sensory category?"
"That is a good idea, but maybe it could also be in an aura category?"
Rainbow and Twilight both began naming things that caused the four other ponies (and one dragon) to look at each other in confusion.
"Does anypony know what they're talkin' 'bout?" asked Applejack quietly.
"Beats me!" said Pinkie, speaking in an odd whisper.
"Uh, you're a unicorn, Rarity, do you know what they're talking about? asked Fluttershy in a quieter voice than usual.
"I think that they're talking about the categories that a spell could be in," said Rarity softly, "But magic's not really my area of expertise. I just tend to use levitation in the boutique and to find gemstones. I do find it odd that Rainbow Dash seems to know about all this, though. Not to rude, but why would a pegasus look up different magic categories?"
"The same reason Twilight looks up pegasi flight patterns." said Spike blandly.
"We've got several good ideas," said Rainbow, "Why don't we go look in the library now?"
"I'll head back to the library once I finish the last few things on my list," said Twilight, "Until then, you can see if you can find anything."
"Sure thing!"
"Applejack, Rarity, I still need to check on the food and the decorations. Could you please show me how each are going for you?"
"Sure thing!" said Applejack.
"Why, of course!" said Rarity.
"Thank you."
Twilight excited Fluttershy's cottage with Rarity and Applejack, being quickly followed by Spike.
"I would say that this has been a strange day for me," said Rainbow, "But I've definitely had stranger days! Do you guys want to come to the library with me to help me look?"
"If you think it's a good idea, I guess so..." said Fluttershy.
"Ooh! Twilight's staying at the library!" said Pinkie, bouncing into the air, "I can set up a 'Welcome to Ponyville' party for here there! Can I come, too?"
"Pinkie, I asked you if you would come!" said Rainbow, "So of course you can! Just nopony mess up any of books and place them all back on the shelves accordingly."
"Um, okay..." said Fluttershy softly, Wow, you're acting so much different since I last saw you, Rainbow...
"Pinkie, can you see if you can find any spellbooks on sensory spells?" asked Rainbow as they entered the library.
"Sure thing, Dash!" said Pinkie, who started to bounce from bookshelf to bookshelf.
"Fluttershy, can you look for spellbooks on auras?"
"Um, okay..." said Fluttershy walking quietly over to one of the bookshelves, "What part of the library should I look in?"
"Er... Do either of you know how the library is organized?"
"Alphabetically!" sang Pinkie happily.
"... You've got to be kidding me. Who organizes a library alphabetically?!? Ugh, it doesn't matter. Pinkie, 'S' section; Fluttershy, 'A' section; and I'll look in the 'M' section for magic in general."
The three ponies shifted off to separate sections of the library and began looking at the many books. Rainbow went at a slightly faster pace than the others, because she at least knew what books she was looking for.
Magic... Magic... Come on! How hard is it to find a book on sensing magic or auras? thought Rainbow irritated, And who organized this library? It makes it impossible to find anything unless you know the specific title of the book!
"Hey, Dashie?" asked Pinkie, popping out from one of the shelves Rainbow had been looking through, "Would a book called 'Sensing Magic Within A Pony' be what you need?"
"Yes!"
"Well, then, I got it right here!" Pinkie thrust the book into Rainbow's face with a large smile.
"Fluttershy, I think we found the book we needed!" said Rainbow happily, landing on the ground with the book.
"Um, you're sure?" asked Fluttershy, walking over to Rainbow and Pinkie.
"Positive," Rainbow opened to the table of contents, before flipping to a page titled 'How to Use the Spell', "Alright, this shows us how to do the spell, but we need a unicorn to do it."
"Twilight could probably do it!" said Pinkie, "After all, her cutie mark was a spark of magic!"
"Actually, it was a blue spark of magic with five white sparks surrounding it, and one white spark in the center. And I don't know how I just remembered that off the top of my head."
"Do you think she'll be back soon?"
The door swung open lightly as Twilight walked into the library with Spike, Applejack, and Rarity following her.
"Okay, I finished checking everything on the list," said Twilight, walking up to Rainbow, "Did you find something that could help?"
"Yes," said Rainbow, turning the book around so Twilight could see it, "We found this book with the very specific title of 'Sensing Magic Within A Pony', and it has a spell you can use."
"You're right, that is really specific," Twilight picked up the book with her magic (which Rainbow noted was the same color blue as her cutie mark) and read over the spell that was written in it, "This doesn't look too difficult to do. It basically shows us an image of what magic would be found in you. Can I test it out on somepony else before I do Rainbow?"
"Sure," said Applejack, stepping forward, "But it won't hurt, right?"
"Nope. The spell essentially scans what magic you have in you and projects it. Are you ready?"
"Ready as Ah'll ever be!"
Twilight glanced in the book one last time before turning towards Applejack. Her horn glowed brighter, with a few sparks jumping off of it, before emitting blue lines that covered Applejack before vanishing.
"Did it work?" asked Rainbow as Twilight's horn dimmed.
A blue screen of magic appeared, listing Applejack's name, cutie mark, and what types of magic were in her.
"I think that's a yes," said Twilight, satisfied, "According to this, Applejack is completely Earth pony, and nothing else."
"No surprise there!" said Applejack happily.
"Do me! Do me!" said Pinkie, bouncing over to Twilight as the blue screen vanished.
"Rainbow Dash first, though." said Twilight.
"Alright, let's see what magic is in me!" said Rainbow, stepping in front of Twilight.
Twilight nodded, her horn glowing bright, again. Blue lines came out again, covering Rainbow this time, before vanishing. There was a moment as Twilight's horn dimmed, before another blue screen appeared, this time with Rainbow's name, cutie mark, and types of magic in her.
"What do I have?" asked Rainbow looking at the screen, "Wait, what?"
"No way..." said Twilight.
"Do mind telling us what's so odd?" asked Rarity, "Because I can't understand any of the data on this."
"Well..." said Twilight, looking at the screen, "The types of magic in a pony are measured in parts out of one hundred. According to this, Rainbow Dash has 55 parts pegasus, 20 parts unicorn, 5 parts dragon, and..."
"And what?" asked Pinkie.
"And 20 parts alicorn!" said Rainbow in shock.
