The events of being held captive by the Diamond Dogs left many scars on the young unicorn, scars that she never wanted to tell anypony about, not even her fiance, Princess Twilight Sparkle. Of course, even small secrets can't get by the observant mare she loved, and one evening, the princess is determined to find out what her fiance was hiding from her. No matter what it took.
