That's called poor writing. The whole revelation and post that could have been so beautifully written. They spoilt the whole show. There was no need to show Riya stoop so low trying to murder her sister etc.
I swear. They just ruined the entire story. With KKB i realize you can't take the story as a whole and you can't focus on details. They literally change the character profile and their focus with the ongoing plot, it's ridiculous.
