In Diya Aur Baati Hum, Bhabho (Neelu Vaghela) and Babasa are struggling with their emotions and they have almost lost hope of meeting their grandson Vansh because of Ankur. Now that Sandhya (Deepika Singh) and Sooraj (Anas Rashid) got to know where their other son Vansh is, there are all possibilities of Bhabho meeting Vansh.
We are aware that Ved got into the same school where Vansh was studying. Sandhya-Sooraj get to know about Vash and are happy to see him. They try to talk to him, which doesn't go well with Ankur and he restrains them from meeting Vansh by putting court orders.
Sandhya and Sooraj hide about Vansh from Bhabho. But the duo is unaware that someone else also know about Vansh being in Ajmer! That someone is none other than Sooraj and Bhabho's Chotu-Aryan. Aryan meets Bulbul and recognises her. He tells Bulbul is misguided and asks her to speak to their parents to know the fact about Vansh.
Bulbul gets to know from her mother that her dad lied to her. Chotu (Randeep Rai), tells about the struggling that their families are undergoing because of Vansh being away. Bulbul says she won't give them Vansh back as she loves her brother a lot. When Aryan insists her to make everyone meet Vansh, Bulbul (Shivshakti Sachdev) agrees on one condition. She asks him to not to reveal the name as she wants Bhabho to know that her other grandson has also got good traditions from Ankur and Sandhya.
Chotu asks Bhabho to accompany him to the temple to Ajmer, so that he can make her meet Vansh. Bhabho refuses as she was busy with household chores. Somehow, Chotu and Bulbul manage to make Bhabho and Babasa meet Vansh. They will be seen sitting with Vansh and enjoying food.
How Chotu and Bulbul manage? Will Bhabho get to know that it is her grandson-Vansh?
