welcome to the new twist in the tale.
actually this twist that the husband (sagar) not only forgets his wife as one of the news item tells us and also that his wife will be introduced as the woman who took care of him when he was sick reminds me a very old and beautiful black and white movie in bengali starring uttam kumar and suchitra sen. the movie name was ' shaath pake bandhan' i suppose it means the seven pheras taken at time of wedding. there the hero regains back his old memory and forgets his pretty wife who also happens to be doctor (thats how he meets her)whom he had married at the time of amnesia. but he doesnot remember anything. and infact to be near him the heroine becomes his niece's teacher. and the movie goes very well.
infact in one of the interaction when the husband asks ,does your husband not take care of you or something like that, she replies ,'oh no, he is very nice'.
old wine in new bottle! wow! but quite interesting actually!
