Anjali has proven again and again that she is an idiot. Remember when nitya was bad and she could not expose her. Every time she would make some mistake.
And she is also too emotional. I mean she finds the Shoraya closed the case, so instead of investigating she goes and tells him. Even after Nitya tried to explain.
But Nitya is not stupid or emotional fool. I mean how else did she fool every one all these years. She does not trust people easily. She will investigate Shorya and find others and find the true culprit.
But if it turns out Shorya is the culprit we will see the past repeat it self. Since Now anjali won't believe her.
But Nitya is the smart one and will expose the killer. She will find the proof and take action and not just scream at the killer saying "I will expose you", "You can't escape me",etc. All the nonsense Anjali used to say.
