well someone had earlier posted that vasu looked suspicious.and i agree with that.
maybe vasu had some relation with a another man and ranvir is their son and maybe aalekh's grandfather found it and vasu din't want everyone to know about this so she made a plan and killed dadaji.
chota aalekh must have seen this when he came to call his dadaji.
this maybe the reason that aalekh is scared of vasu.now vasu knows that ranvir is upto sumthing and she is sending him out so that he doesn't find out abt all this.
well what do u think guys???
