Applejack never left Aunt and Uncle Orange in Canterlot, and became a highly refined mare with a taste for the wild when she isn't attending one of many, many dinner parties. Between such, she has a penpal, a mare named 'Rainbow Dash'. Rainbow Dash sent her some tickets to the Wonderbolts' show in town, in the best seat in the house. When she attends, she's amazed to see Rainbow Dash is the star. They meet for dinner, and things accelerate from there until her aunt and uncle find out. The thought of a highly refined mare with "a show-offish ruffian" is simply outlandish to them. Oh, and the fact that their daughter is a fillyfooler could get her on the streets. Just sayin'.
