one cannot say that her negatiove character is due to Tarun..Traun never asked her to torture Khushi. If she has treated the children (Khushi and Tammy) with a little love and softness, she would have gotten sympathy, even after her wrongdoings. Its said that anyone who can torture a child and hates flowers, have criminal instincts...might be she will believe ajay but still there is time for her to repent..
her negative character wont change overnight..now it will be the worse after she knows about tarun cos wat will happen to her baby...so hook by crook she will do something to make alekh's her baby's father....malti is gone case now so no chance of her exposing sakshi but now she will praise her in front of vasu...i would say it will be sakshi's reign over the rajvansh ...i can see next to fall in his trap is alekh...
