Guy, I highly doubt that the CV's will play out the "CONFESSION" in this manner. Usually, in tellywood confession sequences are played out in 2 3 episodes with fancy settings, long dialogues and high emotional quotient leading to high trps and happy fandom. The cv's won't use this card like this (I HOPE). I think Aditya will go to her house after Zoya invites him and he'll say what we saw in the precap, Zoya will slap her and then Aditya will be snapped out of his thoughts by Zoya. Last minute, he'll change his decision and not confess.
I hope too God they don't make Zoya slap Aditya for confessing because that's a terrible thing to do and it is safe to say that it will drive alot of us away so fingers crossed. Hoping that its a dream sequence.
