S16.E86: The Journey So Far: Nashville - Married At First Sight

There were a couple of sneak peeks.  Who knows what actually happens, but they show Kirsten telling Shaq that if they stay together, he needs to buy a house for them; he asked how she would contribute and she offered that she'd be on the deed, and mentioned pushing out babies.  It looks like it was filmed in a model home.

They had Airris and Jasmine doing what I assume is the sex exercise, and there's mention of being a dominatrix and Airris has Jasmine slapping him on the face, complete with, "No, harder."
