Diamond Tiara and Silver Spoon poke fun at Apple Bloom simply because she does not have her cutie mark. When an arts and crafts fair is preparing to set up in Ponyville, Applejack encourages her little sister to at least participate, but she soon succumbs to her own self-depression. Discouraged, confused, and upset from all the building up of verbal abuse, Apple Bloom one day disappears from Ponyville without a trace and it isn't long before Applejack is driven into mental insanity worrying about her. Silver Spoon betrays Diamond Tiara by confessing to Applejack the most likely cause of Apple Bloom's disappearance and quite possibly her true reason for wanting her cutie mark. And once Princess Celestia learns of Apple Bloom's problem, she decides to pay a visit to Ponyville herself to announce a very important lesson about bullying. Will Diamond Tiara finally realize the error of her ways? Or has her heart been permanently hardened by her own twisted misdeeds?

Also, we have a very special guest appearance somewhere in this story. Think you can find out who?
