Eventually she started openly showing care for Abhi and made him know she wants him.
Now it's more or less like Abhi knows Pragya wants him and loves him too!
Now she almost told him the truth about Tannu, and he is willing to beleive her despite Tannu having proof otherwise.
But a year ago, Abhi was dying to be with Pragya even if Tannu was preggy with his child. And he was looking for a reason to not marry Tannu!!
If she had told him the truth he more readily would have believed her. At the most he would have investigated himself to really make sure Tannu is not preggy with him.
So what was the point of drama!??
Aalu is still kidnapping children.. She can still kill Pragya or Abhi/destroy them. It's not like Pragya took Aalu's hate for Abhi away either. Nor was she able to prove Tannu to be a liar! Again Abhi is believing Pragya more than Tannu here despite Tannu's proof!
So the only things Pragya achieved is-
BB's death
Maa's torture
Innocent little Pari's kidnap/her mom's pain
Etc.
Abhi and her separation for this while.
I don't see the point of this last year of KB.
PS: Of course EK would have sold sarees and kurtis through PraNu, made money with MMS, kidnap, murder tracks.. But from a story POV, what's the point!??
