India TV segment 12/10 - Interview with Tanya Sharma

I'm confused about what Tanya said at the end. The interviewer told her that they have heard her Dadi is about to enter the show. Tanya then says her Dadi has entered the show, though she has never met her because as you know she spent a lot of time away from the family, but now she hopes she will be able to meet her.

But Meera's Dadi is Kokila. 😕

Or did they get it mixed up with Nani and Gopi's mother Madhu is indeed coming back?
