Ganga has always shown the mirror to the Singhs and particularly Dadisa with such tact! And same to Jagya also (that session under the tree in which Jagya confesses to her about his past life etc.).
Out of fear and to much conditioning, Anandi did not really dare to speak much but it is great that Ganga does stand up to her with all politeness and respect and shows her where she is wrong with a lot of tact. Ganga's plus point is her lack of fear. She is grateful but does not make herself a doormat for those who she is grateful to.
