Coming to the silent rivalry between Badi Rani Ma and Rajmata.. To be it just seems like some harmless Saas-Bahu generic tiff which is oh-so-common.. As they say Saas-Bahu is like Mongoose and Snake they hardly co-exist.. I mean come on look at Rajmata and Badi Ranima's Nature, Behavior and Life style.. They hardly match with each other.. They are like North and South Poles.. On one side is Rajmata who is Modern and live by the Western Lifestyle and believes in Showing off the Royalty even if the Royal Treasure is depleting.. Rajmata at times seems very Naive and Easily Influenced.. At times also comes off as Egoistic.
Where as Badi Rani Ma on the other hand clearly hates Western Culture and anything related to it.. She is more connected to her roots and kinda Old School when it comes to Culture and Traditions.. I don't think she is the one who believes in showing off.. She seems to be genuinely concerned about Ranaji's welfare.. Rajmata is too.. But when it comes to save her Royal Stature Rajmata would not blink an eye to sacrifice his own son for it. For example Rajmata is very well ready to marry off Ranaji to Gayatri, even though Ranaji has time and again clearly stated that he has no place for any one in his heart or life except Sulakshana his deceased wife.. But Rajmata would apparently sell off Ranaji to Gayatri's Father and in return not only get free from repaying the loan but would also ensure constant flow of finance from Govind Seth to the Royal Treasure..
Where as Badi Rani Ma is only concerned about Ranaji's welfare.. I think may be, I don't know how right I'm but maybe there is going to a tiff between Rajmata and Badi Rani Ma regarding Ranaji's Marriage as Badi Rani Ma would understand her grandson's pain and would not like the idea of Priyamvada selling off Indra in the name of Marriage and striking a deal with Govind Seth. Just my Opinion..
