@Aqua: At this point, the details of the Parul-Meenu-Mehul situation come down to speculation, based on the few definite pieces of information that we have. Your reading is totally plausible, but it's equally possible that it went down exactly as Meenu has presented it -- Mehul married Meenu for the money, ended up in Rajgarh when he was on the run after she found out, and married a poor, young, beautiful Parul there and impregnated her. Then his scams in Rajgarh get found out (the document Mishti found at the police station there) and he disappears again without a trace, leaving a pregnant Parul behind. I guess they are keeping it ambiguous on purpose, so they can use that for the plot when convenient.
As far as I remember, there hasn't been any concrete explanation for why Parul knew to look for him in Rajkot, or how she found out about Meenu. The earliest flashback we have is of Meenu telling Nanu and Parul that she will take care of everything and not to worry. We have always sort of disagreed on the extent of Meenu's chalaaki taking Parul in so I won't dwell on that too much, but I am still not convinced that it would have made a significant difference if Parul was the legal wife. The way I see it, those labels only matter if Mehul was actually in the picture -- Meenu rendered him moot.
And as we have seen in the show, we don't need that twist to shift the power dynamic -- it's already happening because of Kunal and Abir knowing the truth. I was actually thinking -- what if we read Meenu not messing with Kuhu and Kunal as her holding up her end of the deal she made with Parul on their wedding day? She only started messing with them when Parul defied her and messed with her plans for separating Mishti and Abir. I am not saying Parul is wrong to take a stand, but super intrigued by how it imbalances their relationship. I am waiting for the echo in Kunal and Abir's relationship -- what happens when Kunal decides he's going to stop silently doing all the work that allows Abir to be Abir?
The generosity that Meenu showed in the past is what keeps her character interesting and prevents her from becoming a totally flat villain, so I wouldn't want to lose that with a twist that she lied then too, if that makes sense?
P.S. I am definitely intrigued by the progress of your crush. đ Please keep us updates.
