Later Nandini comes to the temple. Kundan asks her to stop and says you came to get Devimaa’s blessing naa. He asks her to be careful and says your one wrong step and your sister will die. Premal is seen there holding match stick, and tied Sudha to the pillar. Kundan says we have sprinkled petrol on your sister. Premal threatens to burn her. Nandini asks him to leave and asks what do you want? Kundan says you…..Nandini is shocked. Kundan says I want my wife. He sits on the mandap and says I need your approval for marriage. Nandini asks have you gone mad? Kundan asks him to either take pheras or get her sister burnt. Sudha asks Nandini not to marry him and says you have sacrificed much for me, and always gave you hatred. Kundan asks her to think wisely. He holds Nandini’s hand and says sacrificing devi Nandini.
Nandini asks why you are doing this. What you will get. Kundan says revenge from Anandi’s daughter for my parents death. He asks Pandit ji to start mantras and starts taking pheras with her. Nandini says why you are doing this with mom. What she has done bad with you and asks if his love was fake for her. Kundan says I have bear her to reach you and can kill her also. He says I have done everything infront of her eyes, if she couldn’t see then what is my mistake.
Pandit ji asks Nandini to come forward. Kundan takes her forward and asks her to complete the rest of the pheras. Just then they see Krish, Karuna, Shivam and Triveni coming there. Pandit ji runs from there seeing them coming. Karuna is shocked. Krish says what did you think that I will believe you, and will leave my wife. He says it was just an acting so that your truth can come out. Kundan starts acting and apologizes to Karuna. Karuna slaps him and says not anymore. She says I don’t know why I couldn’t see your truth and trusted you instead of Nandini, but not anymore. Nandini frees Sudha’s hand from rope and hugs her.
Sudha apologizes to Nandini. Nandini asks Shankar to come and tells Sudha that Shankar loves you very much. Sudha is shocked. Nandini says if one relation couldn’t work then it is better to leave it behind. She gives Shivam’s hand in Sudha’s hand. Shankar looks at Sudha. Kundan picks the sword kept there. Sudha sees him picking sword and alerts Shankar/Shivam. Shivam fights with Kundan. Premal tries to stop Shivam. Krish beats Premal while Shivam beats Kundan. Shivam’s locket falls down. A fb is shown. Nandini recalls Anandi making them wear it. She recalls Anandi asking Nandini to take care of Shivam being elder to me.
She recalls Shivam asking Nandini to give him a chance thinking him as her brother. She gets emotional. Premal and Shivam continue to fight. Shivam pushes Kundan and tries to stop Premal from hurting Krish. Kundan picks the sword again. Karuna sees him proceeding towards Krish and Shankar, and picks Devi maa’s trishul and throws it towards Nandini, asking her to stop Kundan. Nandini picks the trishul thinking about Kundan’s tortures and stabs him, just as he is about to stabbed Shankar. Everyone is shocked. Nandini throws the trishul. Kundan falls down and closes his eyes.
Nandini looks at Shankar and shows the locket asking if it is his. Shivam nods yes. Nandini asks about his mum’s name. Shivam looks on. Nandini cries and asks what is your mum’s name…..Shivam says Anandi Shivraj Shekhar……Nandini gets emotional. Everyone is surprised to hear that. Nandini calls him Shivam. Shivam calls her Nandini…..Nandini hugs him and cries emotionally. Both of them recall their childhood and cries emotionally. A fb is shown, kid Shivam hugging kid Nandini. Kundan gets up and sees their union….
He takes out gun and aims at Nandini and Shivam. They get shocked. He is about to shoot them, but he is shot by the police. He falls down and dies. Nandini and others see Police there. Police arrest Premal and takes him. Karuna goes to Nandini. A little girl comes there and asks her to save her, and says she don’t want to marry. Girl’s father comes and asks them not to interfere, and says it is our personal matter. Nandini slaps him and asks Inspector to arrest him. She says this is not your personal matter, but society’s matter. She tells that child marriage is a curse on the childhood. Shivam says everyone should promise that there will be no balika vadhu. Krish says everyone shall join hands and take a stand against child marriage. They hold hands.
At home, Nandini sees Dadisaa and she says I am with you always to bless you, but I know you don’t need me anymore as you have learnt to follow my teachings. Nandini hugs Dadisaa and says a child needs elders always. She says whenever there will be darkness in the house, I will think about you. Dadisaa says you will become a big tree one day, who will make our family name proud. She kisses on her forehead. Nandini looks at the rudraraksha and says you will always be with me, and I won’t let you go anywhere.
Later Nandini writes a book on Anandi’s journey since childhood…and says my mum became balika vadhu, her innocence, ups and downs, she has faced everything. A fb is shown from Anandi’s childhood, marriage with Shiv and then her union with Nandini. She says I became doctor by my mum’s blessing and got married to Krish. She says we have fought with Kundan together.
A voiceover is heard, Balika Vadhu is ending after making place in viewers heart. Nandini writes in her book that even though she couldn’t spend time with her, but understood her and her teachings. She writes I missed you mum and I know you will always be with me in our hearts. She closes the book balika vadhu with pictures of Anandi and Nandini on it. With this, Balika Vadhu ended on a happy note abruptly with Nandini and Shivam’s union, but many questions are left unanswered to the viewers.
