Most likely this AnuSar kid will be obsessed with Kalyani, bond more with KalMa rather than AnuSar. Anu will be fine with it and Kaka will hate it LOL. And Moksh will feel left out due to AnuSar beti and potentially KalMa bio child. As per precap, that's the setup, insecure Moksh.
I also have another prediction. I feel Malhar will be largely busy at work due to Meenakshi's escape from jail. And this creep Abhimanyu will try to manupliate Moksh and try to fill Malhar's shoes to get Kalyani. I think only then Malhar will wake up and smell the coffee and realized something is off about this loser.
