I'm one of the people who find it strange when a married woman does not call her husband by his name. So I never liked it when Paro started calling him Major Saab once she wanted to marry him. She seemed fine calling him Jallad when she was his captive and Rudra when she was his fake fiance. In fact I was waiting for Rudra to ask her to call him Rudra. But I guess it grew on me as it became her petname for him.
The way her eyes sparkles, her fond smile and her face lighting up as she calls him 'Major Saab' will be one of the many things I will miss about Paro.
