Amid the passengers' fear, a gang member plants a bomb on the plane, which sparks news and media. But the police were able to arrest the criminals and dismantle the bomb in time.
Upon returning home, Tulsi's soul takes possession of Mohan's body, making Mohan do unnatural things. The family calls a priest to free Tulsi's soul from Mohan's body, but they are surprised when the priest tells them that Tulsi's soul will not leave Mohan's soul until she eliminates her killer, who is a member of the house.
Damini and her mother contact Guru Maa in order to eliminate Tulsi's spirit. She tells them that Tulsi's spirit possesses Mohan from time to time. Mohan sees Damini in a state of extreme fatigue and decides to take her to the hospital. Damini is surprised that Tulsi's spirit has taken over Mohan's body in order to kill her in the burning house where she was killed, but she manages to escape. Radha learns of Damini's communication with Guru Maa and decides to expose them. Radha begins to suspect that Guru Maa is Kadambari. The family decides to celebrate Damini's birthday, but in the middle of the party, Tulsi takes over Mohan and threatens her to confess that she was the one who killed her. Damini confesses that she was the one who killed Tulsi in front of the police and family. At the same time, Mohan and Radha admit that this was their plan to reveal the truth about Damini and that Tulsi never possessed Mohan. Before being arrested, Damini manages to escape and kidnap Gungun. Damini threatens Radha, but Radha summons Tulsi's spirit to help her save Gungun's life from Damini. Tulsi's spirit responds to her on the condition that she appears with the intention of killing her killer, who is Damini. Damini takes Gungun to the valley in order to kill her there, and Radha and Mohan follow her. During the attempt to kill her, the spirit of Tulsi appears and kills Damini and throws her from the valley and saves Gungun.
Tulsi suspects that her real killer is still alive and is a family member. She tells Radha this before she disappears and asks Radha to be aware of her surroundings. Radha suspects that Tulsi's real killer is Guru Maa. She goes to Tulsi's burned-out house in order to search for any clues. She finds Kadambari there and confesses to her that she herself is Guru Maa and the real killer of Tulsi. Kadambari decides to kill Radha by locking her in the burnt house and burning her. While Kadambari thinks that she got rid of Radha, Radha discovers that the bones of Tulsi's body are still there and have not been cremated in all these years. Kadambari is surprised when Radha returns home with the bones of Tulsi's body and threatens her.
Surprisingly, Tulsi walks in with Mohan at that moment. The family decide to hide the fact that Radha is married to Mohan. Tulsi makes outrageous demands to Mohan, even going as far as asking for Mohan to take Radha's mangalsutra off. However Gungun tells Mohan that he need to give Radha back the mangalsutra. Tulsi attempts to kill herself, but Radha believes that she is bluffing and dares her to jump. So Tulsi jumps, resulting in Gungun becoming angry with Radha. Radha tries to warn the family against the fake Tulsi, but they believe she is mentally ill and suggest thar she gets a checkup. It is revealed that Tulsi really had disappeared and the Tulsi in their house was none other than Damini, who is in cahoots with Kadambari. Vishwanath finds about this and tries to warn the others, but Kadambari manipulates them into thinking Vishwanath was lying in behest of Radha.
Damini and Kadambari decide to oust Radha from Mohan's life. They make it seem like Radha threw Vishwanath off the balcony. Mohan finally believes that Radha is mentally ill and sends her to an asylum. Damini and Kadambari then plan to get rid of Gungun by bringing her to wildlife sanctuary. However, Radha becomes aware of the plan and runs away to save Gungun. Damini tries to kill Gungun by throwing Gungun in front of the lion, but Radha manages to save her. Mohan also arrives there, but refuses to believe Radha, as Radha had slapped Kadambari. Mohan blames Radha for destroying his and his daughter's life. At her wit's end, Radha breaks her nuptial chain and cuts all ties with Mohan. Radha leaves with the mental asylum workers.

Mohan and his family have also moved into the same city and live in Meera's house. Gungun is now a teenager and feels that irrespective of Radha and Mohan's personal issues, Radha should not have abandoned her, so she hates Radha.
