Even after repeated lies by Ishu, Dev did not say anything strongly to his mom about interfering in his life and making decisions for him in the past and even now...
In Monday episode, Ishu will pray to all the gods and get chakkar in temple ..soha will accompany her to her home and later dev would tell her that is soha .. her poti..
Now that our drug addict (Ishwari) got Soha's scent and... she would be addicted and would want to bring her to stay at Dixit home for good..
She will go behind Devs back and would file the custody case on behalf of Dev (again for Dev's happiness only) to win dev back ...
It can go three ways ...
1. Sona already has the prenup copy or once Ishu files the custody case..and ishu ke mu pe maregi.
2. our dear Red (VIcky) would give Sona a copy of it as he doesnt want Soha to come to dixit house...
3. Last but not the least, Dev himself gives copy of Prenup to Sona to teach his mom a lesson ... if he does it... his redemption suru hojayega
