Zoya will find the doll at the very last minute and give the evidence in court i iterate at the very last minute when her Visa also is to expire. And when she gives the evidence in court the embassy will also come for her to deport her...But because of the rift between Asad and her and his BIG EGO and the fact that Aayan is grateful for releasing his father he will save her and ask her to marry him.
This is the only justification i can find of the though of Aayan and Zoya since i cannot see them as a couple.
What you guys think?
