Now, take this with a grain of salt, Im just going to report what I heard. My sister's friend works for RH of Miami so this info supposedly comes from producers, but again, grain of salt as I cannot attest to any of it.
Apparently, each year the producers, Housewives, etc get together to kind of plan out the next season. They look at what loose ends to tie up and how to can follow up with storylines. Many times, there are feuds between the women but they aren't up to airing in publically or Bravo doesn't want to air it publically so they kind of manufacture stories to account for the animosity.
Im hearing that the reason Jaq is so upset with Tre is not because of magazine articles, etc. Apparently Jaq was in talks for some endorsement deals but Tre signed on to endorse similar products. Bravo didn't want to air that on tv because it wouldn't fit Jaq;s "character" of the kind, stay at home wife so they used this magazine thing. They know, like good employees, they have to follow Bravo directives and follow the storyline. This accounts to why this argument never makes real sense and why Tre sometime sounds unable to defend herself. Its like she gets stuck because she can't really say what she wants to. Just like the story of the "jokes" in the cookbook. Made up to cover up the true fight (whatever that may be)
There was a producer named Cat(Rodriquez, I think) who had gotten very chummy with Melissa and Jaq. Talk is she had been picking and choosing and editting as she saw fit . This Cat is no longer on RHONJ. Apparently she was fired and is now working as a runner on some other station.
The reason they started filming Season 4 right after 3 was because Bravo thought the riffs between Tre and Melissa were getting better and they wanted to keep that going. Unfortunately, Season 3 episodes were being aired as they filmed 4. As the girls saw the episodes, problems would come back up but they couldn't be address on the shows they were filming. Does that make sense? So a lot of the stories, etc just don't make a lot of sense and much of it is editted and manufactured.
Jaq and Caroline definately hate Teresa, the thing is what they are showing and apparently what is the truth are 2 different things.
Again, grain of salt. I have no idea if this is true or gossip but it came from people working on RH of Miami.
