Sai was literally crying thinking k pakhi didi might have died...looks like she doesn't want to claim her haq...just want to be Dr.aunty in vinu's life...or may be she is afraid that vinu will hate her...if pakhi is not there...as she herself promised vinu a happy family and also pakhi...has manipulated vinu enough in believing ki...Sai the real mother will snatch vinu from pakhi..created a witch image in kids mind...enough damage done..by pakhi didi...
