see.. what i feel is.. nana will give ridz the letter armaan leaves for her.. she gets really upset n starts crying in the fire escape.. (im taking into consideration that the promo is not a dream.. if it is.. my prediction doesn't count).. then, armaan maybe wants to see her before going so he too comes to the fire escape.. and then the promo scenes will happen and hopefully everything will turn out to be ok and she confesses...
