I think there was no need to show that PM aka AB hates Prerna BAjaj for he thinks that Prerna Bajaj destroyed his family and Sam....it was enough reason for him that without thinking a split of second,she shot AB....bt Ekta wants to show this because she wants to prove that if Prerna Bajaj can shoot AB for Rishabh Bajaj,then AB also can destroy Prerna Bajaj for Sam....bt she needs to get a life I think....There's much difference between RB and Sam....Sam is an evil and RB is a true caring lover and husband.....bt Ekta I think has forgotten that basic part.....God knows when this pathetic twist will end and Sam's truth will be revealed🤢🤢
