Yes, it definitely feels like she wants control. I felt the reason she so quickly accepted Simran was that she wanted to get close to Adi. I had written in another post of mine, Adi is the only obstacle for Supreet in the house. Daarji trusts her and takes her suggestions. Ambar is totally under her control. It's only Adi who has been resisting her. Once that is cleared, she can rule the house.
