it could be he has been sent by Ml to play a part in seeing whether the family can stay together. Also as he knows its pranav and sneha who he feels are the heart of the whole movement he wants to check them thru amit.
i thoguht abt it too....but somehow i dun think he cud have done this!!!!you never know mls may haf told amit the address.....but from what i see the way amit was acting towards sneha he is truly in lov wid her and i dun think he wud betray her or play with her emotions....
