Nadia and Mark are devious but not that clever. They clearly are very greedy financially and won’t want to share any income from their YouTube channel with contributors.
However…I think they might be making an exception for Dina, bringing her in as a regular contributor and having their own ‘show’ for the curly cooks isn’t about increasing revenue or subscribers…Nadia can do tit cooking on her own and get the same response. This is personal. This is about;
1 - growing her relationship with Dina privately, by keeping her close, having her do all the planning, shopping and being there at regular intervals for filming.
2 - growing her relationship with Dina publicly, showing the world that she is best friends with her sister and they are extremely close.
This is all with the sole aim of Nadia displaying to Julia that she has won. Dina is the prize, and the more strength Nadia displays in their bond, the less change Julia has of getting proper companionship with the sister she actually likes. I think the moment Julia lost was when she stuck up for her niece’s online safety…that situation forced Dina to pick a side, she had previously remained on the fence and socialised with her sisters separately…but now there is no obvious contact shown, no photos of meals out with the parents and both sisters etc.
I haven’t been watching much recently…but if Lisa has disappeared or become very minimal in airtime…it could be that she has asked how the income works from YouTube I.E. should she be getting payment when she is carrying a vlog due to being the only person in it with a personality.
