coming to the killer my pov is the killer is non other than maya.it cant be kaya.because according to ekthas logic the char which helps r supports the main lead will turn out to be worst villan of the show.thats what happened in case of meera n bani,the same in angad kripa n i think prithvi.so same here.friends we forgot our ippi.she is also very supportive to gauri in the begining right.so 4rm the logic the villan would be maya.because she is the one who is supporting gauri a lot.more than dadi n samar.so its obvious that killer is maya đĄ đĄ đĄ
