One day Jiji has this fit of madness where she killed some1 in their family. The father is an eyewitness to this murder, and just because jiji is his daughter, he hasn't told anyone abt it. So the murder is just taken as a natural death. Jeesa took Urvashi to the doctor who tells him that she's cured for now, but a relapse could happen if she is ever overly stressed. So that explains why the father is so spooked over her. Jeesa must be scared for Tara, because Jiji might do anything. Jeesa told Nahar to not tell anyone until its that necessary because Jiji might have a fit again and she might do something very dangerous to herself and others.
So this is what I think the raaz is! What do you guys think? 😊
