When Gayatri gave rana the free hand to crown Sula the queen as she does not aspire to be rani, only wife, Rana did not hesitate even for a sec and goes ahead and crowns her.
Its like he wanted to make Sula the queen and was only hesitating becos of Gayu.
No wonder she was sending hurt filled signals to Rana cos he did not even for a sec think that Gayu could have remained the queen.He dethroned her,excuse taken was pressure from British and BRM.
Now there is no escape for him, he has to take the decision of patni and there will be no excuses.
Now seeing the power he has given to Sula as queen to illtreat his patni, Im sure he is regretting, and hence addresses Gayu as Rani Gayatri Devi after the dance,reinstating her as his queen.
Good drama playing out there.
