Correlations:

Ok first of, I am really confused on how to think and react about fault of characters etc. I am having contrasting views on that which will only clear next week. But I want to talk about the promo, here goes:
1. Dev with bike: in the accident promo the same type of people that he seem to admonish speeding bikers he became. He seems carefree and rash, not the Dev we know.
2. Ice-cream: During initial episodes when Devakshi went to Dev's award, Sona gets down for Ice-cream and tries to imagine Dev eating that in the road which he was doing now. Then Dev did not eat, now Sona seems to act like Dev eat a little in the car.
3. Age: In Dev's childhood, his father was only present the first 8 years of his life and in his daughter's he won't be there for those years.
This is what I thought so far! I am positive there will be more! If anyone wants to add they can! I will try adding more.
P.S: I thought Shaheer was really hot in that promo! But I am still not sure if that image fits Dev.
