Just One Mistake

Twilight Sparkle and Rainbow Dash have been living happily together for 3 years. They kept it secret for some time, but eventually told their friends. Rarity and Fluttershy seemed uncomfortable with the idea of two mares dating each other at first, but they soon became used to the idea. Everypony was happy for the two. Spike was especially happy because Twilight now had another pony to help out around the library, making his workload smaller and nap time longer. Of course, Twilight still spent plenty of time with the baby dragon. Nopony in Ponyville thought differently of the two for falling in love. Their relationship was what some may call ‘harmonious.’ Was. That was before that one stupid mistake made by a unicorn whom would soon come to regret every word she ever spoke.
