Ever since the Best Young Fliers Competition, where Rainbow Dash bravely took her in her arms and saved her life, Rarity has been rather infatuated with the Pegasus, no matter how hard she may try to deny it to herself. When Rainbow Dash came around to have her Nightmare Night costume fixed Rarity's feeling rose to the surface once again. There and then she made a decision. No more hiding. No more secrets. Tonight was the night she would put everything on the line to steal Rainbow Dash's heart.
