‘Kyunki Saas Bhi Kabhi Bahu Thi’ opens when Karan confesses to Tulsi that he intended to tell her the truth about Rio once she recovered from her illness. However, she never got better, and he was forced to continue lying. Karan breaks down in tears, expressing his guilt. He says he does not know how he could have told Nandini that he was raising Ansh’s child. Karan believes it was fate that brought Rio into his life. He draws a parallel, saying that just as Tulsi raised him despite him being an illegitimate child, he has done the same for Rio, giving him a loving home and family.
Tulsi’s forgiveness
Tulsi becomes overwhelmed with emotion and apologizes for ever doubting Karan’s character. She realizes he was not wrong. Karan consoles her and insists she did nothing wrong. Tulsi continues crying and asks for his forgiveness. Karan takes her back home with him.
Rio’s decision
Meanwhile, Rio and Niyati share a warm moment. Rio lovingly tells his mother that now that he is back, he will not let her face any troubles alone. When Rio learns that Karan plans to return to India, he decides to go back with him so they can stay together.
The truth revealed at home
Back at the house, everyone becomes worried as Tulsi arrives late. She makes an excuse about the car breaking down on the way home. Upon sensing something wrong, Mihir urges her to tell him the truth. Tulsi takes Mihir aside and reveals that Ansh had another son besides Eklavya, and that son is Rio.After knowing the reality, Mihir tells Tulsi not to disclose it to the rest of the family. However, she believes otherwise. She feels Rio deserves his rightful share in the Virani household. Their conversation gets overheard by Karan, who also begs Tulsi not to reveal the truth. He explains to her that over the years, he has done everything possible to keep this secret hidden. Despite his pleas, Tulsi convinces both Mihir and Karan that the truth will eventually come out anyway. She says they should tell Nandini themselves rather than having her find out from someone else. Karan finally agrees and decides to confess to Nandini after he returns from Niyati’s house.
The shocking news
The following day, when Karan visits Niyati’s house, he gets completely shocked when he learns that Rio has decided to move back to India with him immediately.
