How about when he comes out of his own world for a while and asks her why she never smiles or laughs now.
It shows just how much she made an impression on him in Dhulwadi
Her freedom, her laughter, her carefree nature--to him she was like a wild exotic bird that could never be captured.And when he asks her what happened to that Khanak we are struck anew at how that bird has been caged in the city by her circumstances, by fate.
And the only person who can set her free again is this man in front of her.
AND oh.
THAT hug
Their first hug
So tenderly he holds her.The first time he physically comforts her.
