the only explanation I can think of is she didn’t have proof.. and she is gathering proof … bina proof k they will be out in a jiffy… or bachcha milega iski b guarantee ni h…
Between collecting proof and getting possession of her child... as a mother I choose getting possession of the child. But yes, they need to be caught too. So a well planned and timed raid would actually do. Actually in the previous episodes it looked as if Kunal also knows where the baby is. So agar usko pakad liye... he will blurt out everything which will be like his confession and proof against Manushi.... and then they need to time this with nabbing Manushi and getting the kid at the same time.
But after the latest episode, and since the makers are in the mood of making conflicting scenes... now I think only and only Manushi knows where is the kid. Not even Kunal. And Manushi is not even going and checking on the child now. So following her is not helping. Thats the only thing I can think of. So then she needs to first get the info from Manushi.
