They visit the colonel's house and learn that the spirit is his daughter, Malini, who was mentally ill and had escaped from the mental asylum several times before suddenly disappearing one day. The colonel tells them that from that day, his revolver had also disappeared. Sanjana summons the spirit, believing that it wants to tell her something. She learns that Aditya and Malini had an extramarital affair; upon confronting Aditya, he admits the affair and that he had stayed at this very cottage.

Swaroop tells her that this was an attempt by Malini's spirit to separate Sanjana and Aditya to take him with her into the afterlife. He believes that the spirit's next step would be to kill Aditya and that they should go to him before Malini attacks him. Sanjana goes to Aditya and tells him that she is doing this just to save him and that they should leave for Mumbai immediately. It is then revealed that Sanjana is Malini's spirit in disguise.
