Twilight has had enough with Diamond Tiara's constant bullying of her schoolmates, and seeing that no-one seemed to dare step up to her, she finally decided to give her a taste of her own medecine, and challenged the spoiled brat to a private sparring match. Diamond Tiara wasn't stupid, and knew exactly what Twilight had in mind for this fight, but she still showed up, with the intent of beating up Twilight just like she had beaten up all these blank flanks.

The two met in an empty gym at night in Ponyville. Words were said, hands curled into fists, gloves were put on, punches were traded.
