Actually she went there with Rewa to stop TVS. ie. TVS would not do Sugni's sardhakai with Rewa present.
I think she was shocked about Adi doing it. In fact she then cried in front of God in the havali saying why is she being punished. She was angry and upset enough that she almost told Rewa but TVS stopped reminding her of Rewa's status of mind!!!!!
She even had a go at Aditya.
Before MS arrived they were all waiting for her to come and that would put an end to all this so why when she arrived nobody thought to tell her I will never understand.
Why she remained silent at wedding at gun point, I will never know. All she needed to do was to say that if Aditya marries Sugni she will kill herself. That would have stopped it but no she stayed quite but then collected her debt for tying rakhi's on TVS by asking him not kill Aditya.!!!!!
Senile people.
