Seriously, a lot.

(Now with a Spanish translation by the generous SPANIARD KIWI!)

Fluttershy comes to Rarity looking for advice on what to do about an unrequited crush ... but Rarity has a few secrets of her own, and may not be the right mare to ask after all.

Beyond Earth and beyond the Universe within which Earth exists there is a place full of love; the richest mine of love that can be found, as it is seen by those capable of utilizing it...

Within that place, specifically a part of it called the Everfree Forest, awakes one such creature: a Changeling; specifically, a Changeling who had been a human on Earth the day before. How will he survive in a body that literally needs love for nourishment, while in a world that is now wise to the Changelings' tricks and has branded them evil? Better question: Will he be able to change more than his physical appearance?

These questions are not the only thing that will plague him, for the hows and whys of his arrival and transformation are in a hurry to reveal themselves, and Equestria's heart will stop as it waits for its fate to be decided.

Now with a side story (with more to come) from other characters' POV!
POV: MANE SIX

This is a realistic view on how shipping would actually happen in the show. Almost every pony has been shipped with everypony else, but this is what would actually happen if two ponies ever attempted at a relationship.

...

No offense to any shippers, even though you shouldn't take any. If anypony would like to see any other shippings done on this fic, just leave a comment. Maybe I'll write it if I feel like it.

In a freak accident from the Cloudsdale weather control team, Twilight is struck down by an errant lightning bolt. But the veil of death is relatively thin...

==Originally written spring 2011== Equestria Daily Post==
GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

When Fluttershy asks Rarity where she learned to sew, she learns that remembering where you came from isn't always easy.

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.

Everyone knows Pinkie Pie and her love of smiles. But why is she so eager to smile? Why is a smile her most valued possession?

For a person to truly value a smile, there has to be an event, a catalyst that makes them value happiness above all else.

For Pinkie Pie, that event was Sunshine; the sick Pegasus.
