Each pony of the main six randomly starts seeing questionable images within their heads.

Rainbow Dash envisions herself with Pinkie Pie, and vise versa.

Rarity and Fluttershy see these images of themselves, too, and so does Twilight and Applejack.

Twilight decides it must be some sort of pattern, but what does it all mean?

Rainbow Dash had hoped that when Applejack came home, it would be a warm and happy reunion between the two lovers after AJ returned from the latest Apple Family Reunion. However, Rainbow Dash learns that AJ and her immediate family are no longer Apples. They are now clanless and it's all because of her.

Yet sometimes, true family lies not in blood, but in love.

(An old fic I made a long time ago but never got around to posting it, this was made before Apple Family Reunion )
