I had the wild thought (or maybe not so wild?) of dadi being second wife of Vikram Singh, and probably Pujan's real mother? That's because dadi seems way to against Anami here. Just caught up with last few episodes, and the one which was right after Anami's entry in the house, Dadi seemed to be fueling Vikram's mind A LOT against Anami. She looked really against Satrupa as well!
Even if Dadi is not a second wife or Pujan's mother... 😛😆... I find her way to against Satrupa here. MAybe she's in support of Sudha the Red Color, or secretly helping Red Color with the "big plan" to Aag lagao in the Red Mahal.
Honestly whatever it is, dadi does look very Villain-ish! Or she's just too classy and a rude woman, who can't accept the jataon hair wali Anami 🤔
P.S. Your mom sounds funny 🤣 What scene was she talking about?😆
