See, I have this thought in my mind after watching these 2 episodes. Why Vijay behaved the way he did because I for one did not expect it from him. And then I realized that:
It's Raghav! What I got from it was that he got irked not because pallavi was with a man but because it was Raghav. Though he might claim different but it is true.
Secondly, as Sohni once said, Pallavi's so called family is manipulative. And I think this is the first installment of them showing this. Baba if is a heart patient but he never once tried to handle situation? Like pallavi is still young and there are people who have health conditions but they still manage to make some kind of arrangement for their business etc.
Also, that promo might be true in a sense that It can be only Pallavi's mother in law who will support her even when FIL would be against.
Feel free to add your interpretations😃
