Sunday's episode of Naagin 3 begins with Maahir (Pearl V Puri) asking Bela (Surbhi Jyoti) to give her the hospital address where her mother is being treated.
He tells her that he will the pay the bills for her mother's treatment. Bela says that everytjing is sorted.
She then puts medicine on Maahir's wound, and while she is doing that, the medicine falls all over his shirt. Bela then takes Maahir to the bathroom to clean his shirt and face.
However, accidentally Bela turns the shower tap and the water drips on her instead of Maahir. She then gets upset and starts crying, saying that she always messes things up and has never done anything good for him.
Maahir consoles her by hugging her and says that he is happy to have her by his side.
Meanwhile, Sumitra (Rakshanda Khan) is worried about what happened between Maahir and Bela. She wants to know why they were fighting and if everything is
okay between the two.
Andy, on the other hand, says that everything is fine, but Sumitra insists on going and talking to them the very moment.
She goes to their room and knocks on their door. Bela opens the door. Sumitra asks her why she is drenched and why all the vases are broken. Bela makes an excuse.
Meanwhile, Vikrant is hearing Bela and Sumitra's conversation. He thinks that Bela has already killed Maahir and that is why he is nowhere to be seen.
Then Sumitra tells Bela that she wants to talk to her and Maahir about Yuvraj. Bela lies to her saying that Maahir is not in the room, so Sumitra goes to find him.
Vikrant (as Yuvraj) asks Andy what is happening. He asks him to tell Maahir that he and Bela are in love.
Andy then knocks on Maahir's door. This time, Maahir opens the door. Andy is shocked to see all the mess in his room. He is also bewildered to see Maahir drenched.
Mahir makes an excuse and tells his father that he will talk to him in the morning. Andy and Sumitra then wonder what is wrong between Maahir and Bela.
They once again walk then go to Maahir and Bela's room. But since the two are in the bathroom, they aren't able to find them.
Bela and Maahir get scared of hearing their voice and fall into the bathtub. On hearing the noise they walk up to the bathroom and see the two together, and then leave their room.
Later, Vikrant tries calling Bela and wonders why she is not answering. Meanwhile, Maahir and Bela freshen up and clean their room.
Then, while Bela is walking out of the room, Maahir tries stopping her. This Vikrant sees and realises that Bela has not yet killed Maahir.
Vikrant (Rajat Tokas) then questions Bela and her intentions. He says that he has realized that she just doesn't want to kill Maahir. He says that he doesn't think that she will kill him as she is attached to the family, and so he will kill Maahir now.
Bela then tells him that she will kill him and asks Vikrant for some more time. He warns her saying that he will not kill Mahir, but make his life troublesome.
Bela then walks out of his room and acts as if she is fighting with Maahir over the phone. She then visits her mother in a cave and applies medicine to her wound.
Her mother says tells her that she will be fine, and once again warns her about Vikrant and Vishakha (Anita Hassanandani).
Next morning, Yuvraj tells Andy and Sumitra that he wants to marry Bela, and since the two have signed the divorce papers it shouldn't be a problem.
Later, Kuhu asks Bela to accompany as she wants to go shopping. She informs Bela and Maahir that Yuvraj has organised a party tonight. The reason for the same is unknown however.
Poulomi (Pavitra Punia) enters their house and is surprised by the grand welcome. Yuvraj says that he arranged this for Bela and not her. Bela then asks Yuvraj what this party is for. He (Yuvraj) holds her hand.
Maahir comes and asks what is happening. Yuvraj tells everyone that the surprise is for Maahir and Bela. Yuvraj hands Maahir an envelope and then proposes Bela and asks her if she will marry him.
On hearing this Maahir gets furious and has a verbal quarrel with Yuvraj (Vikrant). Yuvraj shows Maahir the divorce papers and tells him that, both him and Bela have signed the papers.
Yuvraj once again asks Bela. He says he will not force her but he knows that she will say 'yes'. Maahir asks Yuvraj to back off and holds Bela's hand. Bela asks Mahir to leave her hand.
