Actually I loved yesterday epi and that hum dialogue. I dont know how many of you have read Eric Sehgal's book " Doctors", but if I had wanted to see Barney and Laura on screen it was there in Ishaan and Aliya.
Always friends through ups and downs going through multiple relations without understanding they are meant to be together and finally a day comes when they know they are not just friends, they cant be just friends and admit their feelings. In the book it was a line that said "They ended their platonic relation" but yesterday on screen that one line flared up like anything.
Yes in deep friendship between a boy and a girl you dont realize what the other is for you, till you lose that person or a third party comes between you.
It's a fact that maybe Malavika has to accept and she herself has to give that spare key to Ishaan's apartment back to him telling Aaliya needs it more than her. I am waiting for that scene. yesterday that key scene precisly reminded me of Doctors where Barney's GF finally lets him go to Laura.
