So from episode and precap, I am able to make out the following:
So this Abhimanyu is the man stalking Kallu and kidnapping Moksh. So he is creating a security threat, only save Kalyani from the security threat. I feel he'll blame all of it on Meenu like all these hamlas are happening because of her, let Meenu escape from jail and come as Kallu's appointed security guard.
Also seems like he's sabotaging all KalMa romance and creating issues for Malhar at work so he stays busy and away from Kallu. So I feel if pregnancy track is happening, I think it'll be shown that Kalyani is 4 weeks pregnant or something cause all future romance will be sabotaged by Abhimanyu. And news of pregnancy will send Abhimanyu over the edge, and I feel he will reveal his true colors.
Anu is noting something suspicious about Abhimanyu, I feel her focus will be on that especially if Kalyani is pregnant, and she will pay less attention to AnuSar beti.
Moksh as per precap already feels ignored by KalMa, so KalMa baby and AnuSar beti will only make it worst.
As for Asha, she has come with a big plan. AnuSar beti was her trump card as Gayu said. I think when AS gave the child away, she thought child was dead and maybe did it to protect Anu. I feel it was Asha and Ahir that maybe bribed doctors to say that baby was dead in order to kidnap. Cause Moksh was also kidnapped around the same time as AnuSar beti so I feel this was a big plan by them for revenge and getting all the Rane pariwaar property, which Ahir always wanted. Or else how does Asha even know all of this? Once AnuSar beti is found, she will make her way back into Rane pariwaar.
