Twilight Sparkle may believe in Pinkie Pie's myriad abilities, but when an opportunity to study them from a perspective she never thought possible arises, how can she resist the chance at the understanding she's always truly wanted? More importantly, can Ponyville survive the trade-off necessary for this opportunity?
