So, now Durga's plan might be to scare Karan by making Divya to pretend as a ghost and haunt him, so that in that fear, he reveals all the truths out saying Goenkas did more than what he and his father did. Then Divya might record his words and give it to Durga. Durga uses it as evidence.
I don't want such lame track like in other shows but the way Karan feared when Rajnath touched him and Rajnath saying you are afraid as if you are seeing a ghost, made me feel that it might be the clue for what is going to happen next.
Hope CVs handle the last tracks carefully and convincingly.
