In one of the previous episodes, Ronnie wants to harm the baby, but Pragya tells him how wrong that is to do. Fair enough. Tannu's baby has no role in the betrayal she is doing to Abhi. She is infact using the child too.
But then, why Pragya only cares about innocence on Tannu's side?
Pragya saw from her eyes that Tannu and her BF took some person away with them mistaking him/her as the blackmailer. Pragya did nothing to protect that person. Very recently she realized it was Maa who was kidnapped and not some "other" person. If it was some random person, Pragya would have never bothered to tell police/anyone some people abducted some random person due to her drama.
When Tannu was in trouble (according to Pragya during PraNu track, Pragya fought so much and got Tannu to MM at the first chance). Now Abhi and her folks are trouble due to Tannu, but why so much delay in doing anything?
Why so much concern for dushman Tannu's baby while much less concern for others.
