John and Marlena return to Salem since it's their home and have dinner at the newly remodeled Chez Rouge (there's a "
sorry it took so long for the re-model!" sign on the door). They sit for dinner, turn their phones off and as they eat, discuss everything that's happened. He apologizes for the nonsense with Kristen. Marlena apologizes for not telling him about them & letting Kristen's line about "If Brady wasn't in my bed, John would be" get in her head. He apologizes for leaving town every eight minutes. Marlena apologizes for being so distant at times.
They forgive, they talk, they hold hands, they dance, then they go home to the Townhouse (it was being fumigated for the past couple of years...pesky Salemese hissing cockroaches, dontchaknow) and reminisce about all their adventures, the love they share, and how they can't imagine life without one another. John drops to a knee and proposes, Marlena accepts and they call all their family & friends to return to Salem the next day where they have a lavish ceremony, a BBQ/carnival/circus reception, and then jet off to Paris for a romantic honeymoon. When they return to Salem, they live in the townhouse, make love every other day, work and have absolutely no un-necessary drama from outside sources.
ALL OF WHICH HAPPENS ON-SCREEN.
