"Fake and staged" is Jana's middle name, even more so than the rest of her family.
Going back to the "bland" discussion, the reason so many people thought that was because that's the image she very intentionally put out there for years. From the beginning, the family would always comment on how talkative she is when there are no cameras, and I always believed that. I think she hates/d the cameras, and the only way she could exert some control over their presence in her life was to just not give the public anything. It's how the whole "poor CinderJana" stuff took off--all we saw was her working for her family while not saying much of anything or exhibiting any kind of personality. And then the Josh scandals hit and the family was at risk of losing the easy money, so she started acting like--well, I don't know if "herself," but definitely like a person and not a smiling automaton for the cameras. And maybe that's just a coincidence and it's just that she's older and more comfortable in her skin. But now she's "evolved" into putting her image out there herself and creating a narrative. Her trajectory has been: give them nothing>>>act like the HBIC of this house that I am because I can no longer get away with not pulling my weight in the TLC family business>>>hey I can make many by just posting cute pictures of myself on istagram without having to answer stupid producer questions!"
