I think it would improve the plot considerably if the CVs were to explore some of Vik's personality in relation to his first wife, Janhavi. I think the CVs are hinting at some mystery around Vik keeping her family away after her death. Also, the insecurity is interesting because it hints at low self esteem. Despite his successful career and fame, Vik is basically an insecure person. In this respect, he is no different from Raj. Although they are very different in other respects, both Raj and Vik are sad at the prospect of losing sarita, and perhaps both feel somewhere deep down that they do not deserve her.
I feel that this new misunderstanding between VISA where Vik feels that Sarita invited Raj deliberately to Mumbai may not clear too soon, as it might fuel the plot further by keeping the suspense of whether VISA will unite.
