Rarity and Rainbow Dash don't like each other very much. However, they are both elements of harmony, so they decide this is a problem that needs to be fixed. Rather than have Twilight set up a sleepover, the pair go off for a weekend of hanging out and getting to know each other better. The only question is: how are the two most dissimilar ponies in Equestria going to spend ten minutes with each other, let alone a whole weekend?
