Yeh Hai Mohabbatein 19th September written episode: Ishita sees Sanjana entering the function hall, covering her head with dupatta. Sanjana avoids going inside, thinking there can be a mess. Ishita tells her to sit outside and goes to attend the Puja of the Tilak ceremony with Raman.
Ruhi and Shravan keep searching for the thief. They see Sanjana under veil and think there must be something fishy. They think they should call the elders. As Raman and Ishita are busy in Puja, they call Madhavi and say that the woman is a thief.
Madhavi chases Sanjana calling her a thief and the latter runs away. All the family members come out hearing the ruckus. Ishita tells Madhavi to stop chasing. She announces that this is Sanjana, Mihir’s sister.
Mihir bursts seeing this and says that he does not know the girl. Ishita thinks he is saying so out of anger. She argues with him. He becomes more disgusted and keeps shouting. Ishita says that he is refusing to recognize her due to Raman.
Ishita mentions that Raman had a past affair with Sanjana and their break up led to Mihir’s misunderstanding with her. Raman reprimands Ishita and tells her to stop all these things. Mihir is completely out of his mind and says that this girl cannot be his sister, as his sister is none other than Shagun.
This is followed by Shagun’s dramatic entry in the function hall. Shagun is relaxed seeing that at last Mihir has acknowledged her as his sister. She says that she became fed up with Mihir’s refusal and developed the plan of exposing the fact by involving Sanjana and using Ishita. She taunts Ishita, calling her foolish!
