Rarity is in trouble. The fashion show that is her only hope to prevent her from a life in poverty is destined to fail when a technical problem occurs.
In this dire situation, she seeks out for the help of Sweetie Belle.
But Sweetie Belle's fears make it impossible for her to help her big sister, until she has an unexpected encounter with somepony that truly understands her.....

This is meant as a pre-episode fanfiction for "Filli Vanilli", explaining my theory how the plot will turn out.
It was written last minute, so, it's probably very rushed, but I hope you find something enjoyable in it!
