The logic behind the scenes starting from Dev's birthday is to show us how sonakshi is made to feel like an outsider. We may feel they are small incidents and had no purpose because it got sorted in the end. But these small incidents give bigger insights about how each character is actually behaving with eachother. Sona already feels like an outsider and had shared it with Dev many times but there are no incidents with which she could be 100% sure so she always gives the benefit of doubt and let the matter rest.. one after other. The bigger the pile, the more painful will be her realization. That pain which will be felt by each of us along with Sona.
This is what they want us to feel for Sona hence the tracks!
