Since the show is anyway going to end, and Kabir and Pooja have married, few things to logically conclude... they needn't show a real ending, there can be a sequel later .... (probably in a different channel)
Kabir should have a solid reason for all this kidnap - forced wedding mess. Probably even a reason that out of vengeance of what she did to Dhruv he married her so that she can't legally marry anyone else and lead a happily married life or trade divorce for the house and business or file for an alimony (he doesn't earn ... so I think the spouse with higher income has to compensate)
Dhruv in the meanwhile,due to the obsession with Jahnavi, should have started collecting all information ... newspapers / facts / figures about Ashok Sharma and his family.... He should meet with people who were affected ... ... with the inspector Raghav who helped his dad... and the inspector should confess what PK did 20 years back ... killings he has done all through his life ... and how he took his revolver to kill Jahnavi. He should also find evidences that Pooja donated land and her profits to orphanage ...He should realize what Mittals have done to Sharmas and get a real eye opener on how bad PK really was... something that no one in his family seems to know
Pooja ... should donate all of PK's wealth and get rid of his paap ki kamaai ... They showed PK as a character who wouldn't mind killing a journalist who asked him uncomfortable questions ...
Chopra's son should marry Rani thinking he'll inherit the wealth ... and come to Ashok Mansion to see it has become a hospital for the poor ...
Chanda, Suman and dadaji - I don't see their characters turning into sympathizing with Sharmas within this limited period since they haven't done it till now.... the house they used to live in (Kabir's friend ) also should go off due to some reason .... and they should be forced to live in Ashok Sharma's burnt house as a only choice and repent.
