Sasural Simar 2 toke the approach of Making Mataji as a Twin Sister in this show. So its Geetanjali and Simar which will be her Dadi Khala Sas.
So they could bring the old cast whenever....
Kokila could of had a sister and it could of been their family while Kokila 2 says I want a Bahu like you Gopi and Gopi come and helps whenever like Simar...
SNS2 is just getting boring. Villans are boring in this show...Saathiya 1 yes it was illogical but it was fun...
