Maybe somehow, Ranchod aka Sidharth gets killed while saving his twin brother Karan. And Karishma holds Abha responsible as if it had not been for her, then Sidharth would still be alive. To avenge Abha she will marry Veer and enter the family.
Because it would be tiring for Karan to play two characters.
But Siddharth is finally growing on me as a character- I like the fact that he gives so much attitude to Massi and puts her in place- finally someone is doing that!
Maybe they can show Karan being in a coma brought back to Ujjain and while Abha nurses him back to health- Sid can have some quality time with his family. But then he and Karishma decide to go back to Mumbai for his career but he will keep in touch.
