On a trip to Manehattan to attend Equestria's most famous fashion show, Applejack and Rarity help each other discover important truths about who they really are. Also, there is dancing.
Applejack offers to keep Rarity company on Hearts and Hooves Day. Rarity is thrilled that she has someone to commiserate with about being single; Applejack is happy to have a date. This may be a problem vanilla oat swirl can't solve.
