From looking at the promo, several things come to my mind. One thing for sure is that Bharti is going to do the exact same thing that Murli did earlier with her and not tell him about what the doctor told. The next thing that I can think of is that not knowing of Gau turning evil,, Bharti would confide in her thinking of her like a big sis about what the doctor told and that would lead Chimti to plot against her. The last thing is that Murli finds out and wants her to abort and she sneaks out of the house at night leaving a note not to search for her (haven't we see this is in countless number of serials) and comes back with the kid after 7 years.
that would be sooo gangsta! I love the idea! 😃
