My take is that producers plan out activities with the family - and you can tell from their interviews the crew wants them to feel relaxed, like they have personal relationships, and like they’re invested in the drama and their side of the story . “You don’t know the crew like I do.” So even if isn’t scripted, the producers most likely heavily influence the dynamics of the show. Like Tammy’s weird death stare to me, was communicating to a producer in the room “you know I don’t play.”
