So, Savita did all the nasty and evil plotting for what? A few materialistic FDs and some money.
Really, one would stoop so low that she would go to every possible cheap and disgusting extent of separating her son and DIL from their biological son. Have a heart woman!
If anything, Savita could realize how luck she is to get a son like Manav and DIL like archu by looking at Sulochana's state.
And then very easily and comfortably, she is accompanying them to the lawyer's office to complete the adoption process.
Oh Savita, when will you change your evil and low ways? Will you ever reform for good?
