Vidya is not actually searching for a missing husband. She is the widow of Arup Basu, an IB officer who died in the Kolkata Metro poison-gas attack. Her entire search for 'Arnab Bagchi' is an elaborate cover to investigate the conspiracy behind the attack and expose the real perpetrators.

Foreshadowing: Early in the film, Vidya insists on finding her husband despite having no official records of his existence, which hints at her hidden agenda.

Vidya uses the prosthetic belly to disguise her pregnancy and appear vulnerable and harmless. This allows her to get close enough to Milan Damji during the confrontation to disarm him. When Damji tries to shoot her, she reveals the prosthetic and uses his own gun against him.

Foreshadowing: Throughout the film, Vidya's pregnancy is emphasized, making her seem like a helpless victim rather than a threat.

Bhaskaran K. is a senior IB official who is part of the internal conspiracy behind the Metro attack. He is the one who tipped off Milan Damji, allowing him to escape after the attack.

Foreshadowing: Bhaskaran warns Vidya to stop her investigation early in the film, showing his vested interest in protecting the conspiracy.

Arnab Bagchi never existed as described. He was a fictional persona created by Vidya to give her investigation legitimacy. There are no records of Arnab working at the National Data Center, staying at the Mona Lisa guest house, or even existing in any official capacity. The entire backstory was fabricated to help Vidya navigate the city and police while searching for the truth.

Foreshadowing: Rana discovers early on that no records of Arnab exist, and locals in his supposed hometown have no memory of any Bagchi family.

Sridhar's computer contains encrypted information that, when deciphered, reveals Bhaskaran's phone number. This direct connection between Sridhar and the senior IB official provides the proof Vidya needs to expose the conspiracy. The data becomes the evidence that leads to Bhaskaran's arrest.

Foreshadowing: An errand boy identifies R. Shridhar as a frequent visitor to Damji's place, connecting him to the conspiracy network.

Vidya is aided by retired Colonel Pratap Bajpayee, a former IB officer who had long suspected the involvement of high-ranking officials in the attack. Together, they crafted the elaborate scheme involving the fictional Arnab, manipulated the police into helping her investigate, and strategically used the IB's own resources to expose the conspiracy from within.

Foreshadowing: The cooperation between Vidya and Rana is too seamless, with Vidya always knowing the next move, suggesting deeper planning.

The final twist reveals that Vidya is actually the widow of Arup Basu, the IB officer who died in the Metro attack. Throughout the film, she has been using the fictional 'Arnab Bagchi' story as a cover to investigate the conspiracy. Her entire journey was a calculated vendetta to expose and destroy the corrupt officials behind her husband's death.

Foreshadowing: Rana's final realization that Vidya and Arnab never existed as described hints at her true identity long before the reveal.
