Twilight was kicked out of the wedding by her brother Shining Armor and then abandoned by her friends and mentor after accusing Princess Cadance of being evil. But it turned she was right, Princess Cadance was really Queen Chrysalis in disguise while the real Cadance was trapped beneath Canterlot. Twilight found her and brought her back, proving she was right. In the midst of all that chaos, only one pony had the chance to apologize, but the others need to say their peace as well after the changelings are defeated.
My first fanfiction, inspired by other stories including Post Nupitials, Canterlot Healing Process, and Little Sister Best Friend Forever. Part of my Headcanon and Apology Verses.
