Applejack's parents, Jonagold Apple and Ginger Gold Apple have known each other for 27 or 28 years now. Even though they've known each other for that long, they are still discovering new things about each other. One of which is that they are both spies working for rival agencies. They were both sneaking out at nights to assassinated ponies.
What will happen next in this epic tale of love, lies, action and drama in Mr. and Mrs. Apple.
(Note: In cause you were wondering, I kept the therapist idea and the spy idea from Mr and Mrs. Smith.)
