Shouldn't she have atleast questioned her about cheating Suman of the kangans if not other things?
I agree she didn't know that Pandya store was mortgaged because of Mami and how she cheated their father of all the money and he eventually died. Dhara and Gautam worked hard to bring it where they want now😕
Raavi is emotionally and physically drained. She's stuck in a marriage where her husband doesn't like her, is rude to her, and manhandles her. Then she has Maami, who's her mother, the one who raised her up as her own. Right now, Raavi is so troubled that all she wants is some peace in her life, she's trying so hard to become Raavi 1.0 but the people around her aren't letting her be.
You see, when you are stuck between two difficult choices, one is evil but has always been good to you, and the other is good but has always been so hard towards you. It is obvious that the person will deviate towards the first choice.
All Raavi wants is peace and happiness in her life, and to be loved by the people around her. Maami is that person right now and not Shiva. So its obvious that she is going to take Maami's side for now. But didn't she also said to Maami that she cannot talk to Shiva like that. And that's when Shiva shouted at her.
