Raman and Mani confront her for lying to her about her presence at the club.
She lies to them once again. She tells them that she is innocent and won’t accept any false blames. Raman asks her if Sahil is blackmailing her for becoming Shaina. She tells him that there is nothing like that and he is hugely mistaken. She yells at Raman for accusing her so badly that she is involved with Sahil. Raman finds her behavior very strange and wants to know her problem. Raman and Mani share the big problem with Shagun. They tell how Ishita is driving them mad by her dual personality.
Shagun doesn’t think that Ishita can be involved with Sahil. She asks Raman to apologize to Ishita by meeting her at the clinic. Raman doesn’t think he is at any fault. He refuses to apologize, but Shagun insists him to accompany her so that he can sort his differences with Ishita. Meanwhile, Mr. Bhalla follows Ishita to give her some dentures box, which she forgets at home. He reaches her clinic and sees her in a different avatar. She leaves in a modern dress and drives off in her car. She hits a man and yells at him for coming in front of his car. Mr. Bhalla worries seeing her rudeness and different personality.

Raman gets puzzled and wants to know the matter of Ishita and her lookalike. There are many complications in Bhalla family because of Ishita and Shaina’s confusion.
