Ram and Priya will be connected, will be husband and wife. He not only calls, but continues to consider her as such. Therefore, he argues, fights and pushes away. Not her, but myself from love, which screams about the truth, and the mind, littered with false stories about pills and everything else, screams back.
That's why he was so exhausted in the hospital and made a promise to Pich. They both will never be able to live without Priya, the wedding can go through, the interview can go through, the altered DNA test, Krish and Ishaan's broken plan, Vedika's lost chicken earring, the bribed doctors, everything can go through except Ram and Priya's connection. Their love lives and will live through many more storms, like a mighty tree with strong roots, supported by young twigs and leaves, in the face of baby Pihu.
It was not in vain that Ram saw the doctor played by the beautiful Taapsee Pannu. She was right, peace comes with time. For Ram and Priya, peace is to be together forever and find each other in the dancing crowd.
