After seeing today's episode, I think we can be somewhat more generous w/ what one thinks the CVs are trying to show
For one, Neeraj and Sandhya are shown as trusting each other, despite all the circumstantial evidence. Hence, when Anjali showed Sandhya those pics, she suspected that Anjali did something to get him into her room. When Neeraj tried to explain to Sandhya, she told him that she trusts him more than herself, and hence, he needn't doubt her trust by explaining things. So as far as trying to win this game by creating differences b/w Neeraj & Sandhya, it's not going to work.
After that, Anjali gave Sandhya an untimatum to leave within 2 days or else she'd show everyone the photographs, but this time, Sandhya's showing no signs of leaving. She showed those photos to Purvi, hoping that she'll talk sense into Anjali, and that can go either way. If Sandhya tells Sarita and convinces her, particularly if Anjali tells her the same, then it'll be a Vrinda moment - this coalition will be cracked.
Only thing I don't like is Sandhya being poised to be the sole cook in the house - here, I agree w/ Sarita and Purvi that they are other bahus as well who have that right and precedence. Also, it lends an edge to Anjali's insult that Sandhya's place is only in the kitchen. I know that the CVs are probably showing this to demonstrate how Sandhya is spreading her love for Neeraj on to his family, but honestly, I think that Neerdhya is better off leaving them. I'm waiting for the day when all the family members spill their guts out about their resentment of Dadaji, and how they hate Neeraj. Once Sandhya sees how Neeraj is hated, she'll stop pressurizing him to stay, particularly if it looks like he'll inherit the property as a result.
