Fire investigator Kothandaraman questions Trilok about the history of the factory and its financials.

Regina tracks Adhisaysm's phone and finds out he had called Nila several times the day she went missing. Since none of the boys are returning phone calls, Sakkarai offers to go to Munaar to investigate. He is surprised to find Nandhini there, who is also looking for clues on Nila. With help from local police, they track down Adhisayam's van and his hideout. They catch all the friends, but no sign of Adhisayam or Nila.4"The Immersion"Bramma GPushkar–Gayathri17 June 2022Shanmugam and his group lose patience and force their way into Regina's house. Nandhini and Sakkarai return just in time to stop them, and reveal Adhisayam and Nila are actually in love with each other, and eloped to Mumbai. From the phone he got from the other boys, Sakkarai plays a series of voice messages Adhisayam had recorded for Regina. Adhisayam recounts his romance with Nila through those messages, and mentions they decided to elope because of the personal enmity between Regina and Shanmugam. Sakkarai opines to Nandhini personally that he always thought of Adhisayam as a happy-go-lucky guy, but these messages appeared to come from a wiser person. Regina and her husband blame each other, but Shanmugam seems to repent for his mistakes.

Police check the train schedule. They find the names of Nila and Adhisayam on the reservation charts, but on a train to Guwahati, and not Mumbai. Ticket inspector cannot recall them either.

He unlocks the phone with Nandhini's help, and they find out Nila was quite active on social media, contrary to their beliefs. The also find out Nila was obsessed with the disappearance of another local girl Ammani, several years ago.

Police trace Pushparaj's bike near the venue of a procession for Mayana Kollai. Shanmugam's brother Guna is playing a major role that day. Sakkai catches Pushparaj there and finds out he was looking for the phone because it contains pictures of him being intimate with Guna's wife, Selvi.

Regina is not handling her loss well, and her marriage is strained.

Vadde's and their accountant Vadivelu (Regina's husband) discuss the company cannot survive unless the damages are covered by insurance, and Kothandaraman's report is crucial. Kothandaraman investigates the burnt down factory with Sakkarai and Guna, and discovers a few items not in compliance. The office who investigated from the police side, admits his report was completely based on Trilok's suggestion. Guna develops asthma symptoms and leaves the factory. Sakkarai suspects if the attack was triggered by anxiety over the investigation.

Sniffing dogs lead police to some caves near the lake, where they see signs of a ritual and traces of blood, and suspect if the kids were sacrificed for Mayana Kollai. Sakkarai finds a tent where a recluse called Eswaran lives, and discovers a box with Rs 2 lakhs. Police arrest Eswaran and interrogate him. They find out Ammani was his sister, and became deranged after she went missing. He admits Nila and Adhisayam offered his Rs 2 lakhs to kill someone, which he refused, but still snatched their money. Forensic reports confirms the traces of blood in the cave is from a goat and Eswaran is probably innocent.
