[I swear this will be continued... eventually]
Time Turner goes missing: the Tardis doesn't return one day. Or the next day. Or, the day after that. After a week passes, Derpy and Dinky lose all hope of ever seeing him again. Then, things go from bad worse. Nine hundred years ago, Princess Celestia passed a law about custody suits, which contained a fine-print technicality that had never applied until now. The technicality was that if a single parent had a debilitating disability, they lose custody of the child to the state. Unfortunately for Derpy, her clumsiness and lazy eye were officially filed as symptoms of a mental illness. So, the FPS, Foal Protective Services, is forced to wrest her daughter away, much to the chagrin of the entire town of Ponyville. But, they won't take this lying down.
Cheerilee, who minored in law while she got her teaching degree, headlines the defense in the custody case. Can the unity of a town keep a shattered family from breaking even further? Or will the bonds between a mother and daughter be severed permanently...?
