I'm completely in agreement with you on Arnav comforting Khushi part. Since I'm one of those for whome comforting others become difficult for me, not knowing what to say or how. But i try to be there for the person and a silent support. That is exactly what Arnav is doing. Being there for khushi.
What more he even kicked his attempts to save his sinking company image by agreeing to fly economy. And khushi knew asking arnav fly economy wouldnt be ok, yet shewanted to reach her babuji asap and her not making eye contact revealed same to Arnav.
There may be time for them to show trust through there gestures but they are able to read other and what other want. Lets see what future holds.
