Episode 3 of Naagin Season 7 starts with Purvi (Priyanka Chahar Choudhary) entering the meeting room, carrying multiple bags in her hands. Aryaman asks her about the report, to which she replies that she hasn’t started working on it yet. Aryaman then asks her to prepare a glass of wine for him. Purvi tells him she doesn’t know how to make wine, so Aryaman tells her to learn it. Purvi searches on the internet and serves the wine to him. Meanwhile, Aryaman’s sister tells Rajat to meet Parmeet, saying she can’t accompany him because she has to prepare for the 9 p.m. news. Rajat nods and leaves.
Purvi prays to God to help her manage everything since it’s her first day at work. Later, Ananta (Eisha Singh) tells Purvi, “Let’s go home.” Purvi says she has a lot of work, so Ananta can go alone. Ananta leaves, and Purvi dozes off while working. Aryaman taunts her for sleeping during office hours. Purvi wakes up and gives him the report. Aryaman then asks for coffee without sugar. After having coffee, Purvi starts feeling itchy and suffocated, so she goes to the terrace. Rajat sees her and decides to follow her.

Uttara recalls all the previous Naagins’ transformations and says this is the beginning of Pralay. Rajat sees Purvi’s transformation and screams in fear as he realizes that Purvi is a Naagin. He decides to inform Parmeet about it, but Purvi faints before he can.
Parmeet’s brother insists that Naagins don’t exist. Rajat then tells Parmeet that the Naagin is outside. Just then, Purvi enters with a file, and Rajat points at her, saying she is the Naagin. Shocked, Purvi denies it, claiming she’s human. Parmeet asks her directly if she is a Naagin. Frightened, Purvi runs away. Rajat starts laughing and reveals that he was joking. Angered, Parmeet throws Rajat out.
Rajat goes to his car, where he transforms into his true form—Bharni (Alice Kaushik). Bharni opens the car trunk and finds the real Rajat tied up inside. She warns him to escape and never return. Rajat flees but meets with an accident. Bharni and Uttara witness this.
Purvi realizes she can now see everything clearly without her glasses and finishes her work quickly. She informs Aryaman that she has completed the week’s tasks, impressing him. Later, Purvi misses her bus and runs behind it to catch up. The driver is shocked by her speed and asks if she is an Olympic athlete. Purvi starts wondering if she has become some kind of superwoman.
Uttara tells Bharni the story of Rishi Kashyap and Vinasha, explaining how Karud killed all snakes to avenge his mother. At that time, Sheshnaag sought help from Lord Narayan, which is why their clan still exists.
Ananta tells her boyfriend Ravish that she is pregnant. Ravish asks her to trust him, promising he will talk to his family after Karan’s marriage. He excuses himself, saying he has a meeting.
Purvi later learns that Ananta is pregnant with Ravish’s child. Concerned, Purvi warns her that Ravish is rich and might betray her. Ananta assures her that Ravish loves her and will handle everything. She adds that Purvi will understand love one day. Meanwhile, Ravish is seen romancing Savarna, his father’s friend’s wife, who reminds him that she’s already married to an older man.
The next day, Purvi hurries toward Aryaman and nearly falls, but he catches her. Aryaman sarcastically tells her that he can begin his show if her circus is over. Purvi wonders why someone so handsome can be so rude, hoping Ravish isn’t like him.
Mayuri searches for her boyfriend at the office. Purvi sees her in Parmeet’s cabin and asks what she’s doing there. Mayuri replies that she is looking for her boyfriend and even shows a suspicious video to Purvi, saying something strange is going on in the office. Purvi agrees and decides to talk to Aryaman. However, Aryaman dismisses her, saying he can’t handle her clumsiness again. He receives a call from his aunt, realizes he’s late for Karan’s engagement, and invites the staff to the event.
Meanwhile, Parmeet takes his friends to the basement to show them the dragon. He says the Mahakumbh is approaching, meaning the Pralay is near. He explains that the dragon hates Naags and Naagins and assures them there’s no need to worry as the creature is extremely dangerous. Parmeet’s friends praise him. Parmeet boasts that India’s growth made other nations jealous and recalls how he killed the real Parmeet and Dr. Tushar. He then says, “Let’s prepare for Mahakumbh.”
Mayuri notices the lift, which is always closed, standing open. She enters it, and Purvi follows her. The dragon senses Purvi’s presence and becomes restless. A security guard tells Purvi to come out, saying the lift is only for owners.
Later, Purvi visits Aryaman’s house, where Uttara and Bharni also arrive in human form. Purvi tells them they look familiar. Uttara thinks Purvi’s powers are awakening, which is why she’s drawn to them. Purvi admires the surroundings and wonders how to find Aryaman in such a large house.
She mistakenly asks Aryaman—assuming he’s a servant—for a glass of water. Aryaman jokingly asks whether he should serve poison too. Purvi tells him that she can now see clearly without glasses and wants to show him something important. Aryaman thinks she’s drunk, but Purvi firmly replies that she doesn’t drink and advises him not to either. When Aryaman asks why, she sweetly says, “Because I want you to live a long life.”
Meanwhile, Mayuri gets shocked seeing the dragon, which then captures her. The episode ends there.
