One day in Canterlot, a mare comes to the city square selling wildflowers from the countryside who happens to get some looks from its locals. Celestia in particular investigates because she looks like the very pony that she hasn't seen in a long time.
The problem? That said Alicorn mare doesn't recognize her.
