Well, sadly everyone is sidelined apart from Gauri and Dadi. Rohan and Daljeet are made to look like pieces of furniture in the show. Their characters have noT developed and if they get two lines per week, they ought to consider themselves lucky.
The story was never about Kali and Gauri. The story was how to combat superstitions and how a girl who was saved like Sita was found, eventually goes on to find happiness. It is Kali's story. Gauri was important then, because she helped the KT title to remain in focus AND she continuously as a youngster tried to save Kali thus overriding the KT angle.
And now it should be Kali and Yug and how Kali goes on to fight this superstitions nonsense being a suhagan. And eventually finds happiness.
The actors offscreen need to stop with their nonsense about how the show is all about Kali-Gauri, because its not and the proof of how the audience dislikes the focus being on them, is the ratings of the show.
