"Miss Sparkle," you begin in your most heroic voice, "it would be an honor to lend you my assistance!"
"That's great!" Twilight's face lights up. "I'm... not sure how you knew my name, which strikes me as pretty creepy, but we don't have time for fussy details like that!" An explosion suddenly rocks the room you’re in. Or rather, the tree you’re in. That’s right; you’re currently standing inside Twilight’s tree house-library-abode-thing. You hear a menacing cackle drift through the air, and at once you know what she needs your help for. After all, you’d recognize the sound of John DeLancie’s laugh anywhere. The unicorn gives you a sheepish grin. “You can hear what kind of trouble we're in. That’s kind of why I’ve called you here. Allow me to introduce myself; I’m Twilight Sparkle, and this is Equestria.”
She proceeds to inform you about Equestria and how she transported you here. As much as I’m sure you’d love a dialogue about all the things you already know and don't care about, I believe I’ll just skip on ahead.
“… and that’s how Equestria was made.”
“I see. Fascinating.” You yawn. “So, you’ve brought me because I’m the best individual to deal with Discord, correct?”
“Actually, I fudged the spell. I grabbed the nine hundred billion, three hundred and sixty two million, forty-two thousand, three-hundred and fiftieth individual most qualified.”
You mentally patch up your injured pride. That’s got to be in at least the top fifty percent, right? you contemplate.
“Very well,” you continue, "so why don’t you handle Discord yourself? I mean, you beat him once before.”
“You’d think it’d be that easy. Unfortunately…” Twilight walks over to the front door and opens it. She attempts to move her hoof through the entrance, but is stopped midway by some sort of invisible force. She taps a few more times and you can hear a dull thunk each time, the air seeming to ripple upon each impact. “Discord has thought ahead. Not only has he turned all my friends into shells of their former selves, he’s also trapped me inside my own home with a force field. I can’t even teleport past it!”
“If I may be so bold,” you remark, “it seems you are currently in quite the pickle. What am I supposed to do?”
Twilight gives you a knowing smile. “Because I found a loop hole. When Discord trapped me, he said, 'This force field is so powerful, not a single living thing on Equestria could possibly get through!'”
You think on this. Finally, it hits you. “I get it!” you proclaim, "you're going to kill me, throw me through the force field, and then resurrect me! I’m not “living”, so it doesn’t count! Brilliant!”
Twilight gives you a look, very similar to the one your mom gave you when you suggested that, if you flooded the basement with water, the family would have a new swimming pool. “Yes, that could work in theory. Or you could, I don't know, just walk out. After all, you weren't originally "on Equestria”, were you?”
“… Was I?”
“No! Now get going! You need to return all my friends to normal so we can use the Elements of Harmony and defeat Discord!”
“So, um, how do I do that?”
Twilight lifts a sack off a nearby table and hands it to you. “Last time this happened I had to get all my friends to remember the power of our friendship. That required holding them down and pressing my horn to their heads.”
“Kinky.”
“Shut up. I've enchanted each Element with memories of our friendship. Just get the Element around the right friend's neck and the enchantment will do the rest. It will flood their brain with memories of all the good times we've had in the past, returning them to normal. Any questions?”
Now that you think about it…
>”Do you have a bathroom in here? I forgot to go before I was trans-dimensionally teleported.”
>”How do you get your mane like that? I mean, I’ve got a barber, and even he ain’t that fancy.”
>”What’s one divided by zero?”
