As far the story tulsi n cheema has a child.it is good twist.but,who is that child?is it aryan or aradhya?bcz there is child exchange twist also there.so there is possibility that aryan is tulsi n chema,s son and aradhya is pavitra n saswat,s daughter.
But i think the twist of child exchange will ruin the whole show.bcz the show about a devdasi girl,s marriage with high caste boy.but,after this twist it will be vice versa,aru instead of dauther of devdasi,she will be daughter-in-law of devdasi.
I dnt think this child exchange twist was needed or necessary.
