The batpony guards gazed upon both the mare and their princess. In their ears they caught the sound of fangs retracting. Though it was very soft, almost inaudible. Any normal pony wouldn't have been able to hear it. Though even with the help of their greatly developed ears, not even they could judge from which mouth the sound originated from. Did they came from Rarity's? Or from Luna's? Worry took over the eyes of some guards while others tried their best to hold their nerves.
