I think either Tanya or Nadani killed gujral or maybe he is a live and this is a fake death as Ekta likes those type of tricks in her shows.
and maybe that mask Woman must have been Tanya and she took Bhoomi with her so that Gujral won't hurt her.
now this will go for at least two weeks to just find out if he really is dead or fake he's death. and if he's dead who killed him?
