Local Ponyville folklore says that the mysterious colt that just moved into town hides a mysterious secret. Some say he's a government spy, plotting to take over Equestria. Others think he's just a shy stallion who has trouble talking to others. When Derpy Hooves, the resident mailmare, delivers a letter to the reclusive pony, what she finds is not at all what anypony had expected--least of all herself.
