Now we know that Palaash had something up his sleeve all along. Even though Nimmo didn't believe Kunal at first, she is going to eventually. I am hoping whatever Kunal does for show, he still keeps watch over Nimmo, who else will? Palaash is a wolf in sheep's clothing. I said in an earlier post, that I hope we don't see him again. But I take it back, I hope they drag him back to stand trial and confess to his plan. That he deserved all of Kunal's temper and much more! And I think his bua is kind of fake looking, like she has a lot of tan makeup on to look older. I could be wrong. I say this because I have seen women wear it in a wrong way and it looks unnatural, like her. And the glasses, could be part of her guise.
I would bet the farm that Palash burned the warehouse, knowing his father-in-law would go to prison for it. how will they prove Nimmo's innocence without first proving Palash's guilt?
I think Naina could have taken the diamond and set up her sister as well. I wouldn't put it past her as she is a snob.
