In a bizarre alternate universe where many things are opposite, cutie marks are chosen not by destiny, but by bureaucracy. Apple Bloom, unsure of her fate, decides to take an extra year to pick her cutie mark, but Diamond Tiara is unusually motivated to make sure that doesn't happen.
Meanwhile, Prince Blueblood, sort-of-kind-of-not-really heir to the throne and only son of the universally beloved Princess Celestia is having another average day at the Cutie Mark Bureau when a horrific attack leaves him without his own mark of destiny. What comes next makes him question everything he believed...
