my predeiction is about sid is tht
i think sid lost him memory even though he got into a car accident somehow he was saved
then arjun's wife probably found him and told him tht she is his wife and he has a daughter becuase probably arjun was dead and she wanted her daughter to have a dad,so she made it up to conveince sid..
and he probably got convienced becuase she probably showed sid the picture of arjun and his family,and then sid probably believed he was arjun
wht do u guys think?
