the way it was shown that tushar's memory is back was quite funny.......it was like tribhuvan is telling tushar bout kareena and he immediately says that he remembers everything now and then shouts mom....dad....pk
the makers should have shown in an another way.....like A) he see's kareena somewhere and in a period of time, he get to remember all the past OR B) he gets hurt in the head which brings him back to normal.
