2. I thought it was funny that Vikrant wondered if Sarita had left his house due to his anger. He is yet to find out that our Sarita is made of stronger stuff. She has had good training for 10 long years of dwelling in entirely loveless situations. Even in her previous marriage, Kamla kept trying to throw Sarita out, but she remained adamant and remained with Raj despite the fact her "love" for him was entirely one-sided and unrequited. Now that Abhi adores and loves Sarita so much, there is zero possibility of Sarita leaving. Will this have the effect of cooling Vikrant's insecurities and anger, or will it encourage him to take her for granted like Raj did is something we have to wait and see.
3. I do think that the presence of this Vandana and Kajri (or whatever her real name is) detracts badly from the main plot. Today's episode was just boring with predictable drama through and through. Such continued and needless interference from the villainous elements wastes valuable air time without furthering the dynamic tension among the main leads, or moving their stories forward. Even without these elements, Abhi could have been shown to have accidentally spilled his paint, or sustained a fall. Such things do happen routinely in the lives of children without needing to have Kajris and Vandanas tampering with paint bottle lids. The CVs could have focussed on the lives of these three --the father, mother, and child, without contrived drama. I hope that after the next TRPs are released, Vandana and family will be sent off from the Suryavanshi household.
4. Why did not Sarita put her foot down at Vikrant inviting his in-laws to stay with him, specially considering the history between Sarita and them? Well, it is perhaps Sarita thrives in difficult situations, and likes to take up challenges. The more she is pushed, the more she digs her heels.
