In DK this was more or less towards the end of the show. It was not her reaction but Dr Ahmer's reaction that was stressed on.
I that Zoya agrees with to sell the house to the 'client' not knowing the client is none other than Ahmer himself. That too because her dad is in financial difficulties...(here also I think that partner may create financial problems for nidhi's Baba which may make her accept the lawyer's offer).
Ahmer then took Zoya to show her his dream house which would be theirs, and on alighting from the car she confesses that she is the one who has been left that house. As expected Ahmer's anger takes precedence to his rational thinking and he refuses to buy the house. Later on when he hears that Zoya wanted to sell it because of her Bab's financial difficulties he buys it but accepts his friend's offer to go abroad to work...and leaves the keys of the house for Zoya before leaving the country. Zoya then gets all desperate when faced with the fact of losing Ahmer for good and goes back to the house which was Ahmer's reason for existence...But finally Ahmer does not catch the flight and in the end both meet at that house only ...and forgetting all their gile-shikways they unite...
Very simply done and very well done..can't forget the ending scene...
