During her fashion internship at Prim Hemline's boutique, Rarity is tasked with designing a new window display for a visiting Fashion Week style scout. Unfortunately, the pressure starts to get to her, and she confides in Sunset Shimmer. As they walk through the city, they come upon some graffiti drawn by a mysterious and popular street artist named "Flanksy", and Rarity gets inspiration. Later that night, she is dissatisfied with her finished work, but Sunset gets an idea. The next day, Rarity returns to the shop and sees a crowd of people impressed by the now improved window display, including Prim Hemline. Looking behind her, Rarity sees Sunset in an alleyway with paint on her cheek and realizes that Sunset is in fact "Flanksy".
