Twilight and Trixie go through the adventure of life together, the other as their sister. Things go smooth for both mares, but as fillies their lives are more than unusual. While Trixie fights homework, school work, everything else that involves work, as well as her mother, Twilight stands alone as a golden child. More often than not, the sweet alumna sees herself saving Trixie from trouble around every corner. As Trixie lives life to the fullest, exploiting her sister for everything she could, Twilight prefers the quiet way, keeping Trixie in line as best she could.
