Frankly, I don't think there will be any misunderstanding between Raghav and Pallavi. Infact I feel that Pallavi's trust in Raghav will strengthen. And I feel that Raghav will once it for all face and fight his fear of "Pallavi abandoning him". I don't know why I feel that this Mandaar who is entering isn't the real one. Cause the real one was a shy, submissive,repressed character who could not overcome the overwhelming bossy behaviour of his father. And if this one will be overtly grey, then either he will be a sneaky pest who cleverly covered this side with submission or he is a slime who has come to take his place. I think it's Ved's game plan.
I feel Pallavi will have doubts about Mandaar and to disclose his truth, may leave Raghav to uncover the mystery. But Raghav won't know the truth. Just like Pallavi does not know the truth about the accident now. Inn logo ka rinse and repeat bahut chalta hai between Raghav and Pallavi. This track has so much scope to show the crazy lover side to Raghav. I mean we haven't seen much of what Raghav can do to get the woman he loves in his life. And society ka rules or law of the land doesn't matter. So let's see what happens. I saw a side to his madness when he coerced Pallavi into marriage. But I would love to see his grey side in love for sure.

That's reason for Sulo's hatred towards Pallavi. She didn't like Mandar either.
