I do not think She can be Swati , if she would have been , i do not think Niranjan had any problem if Aditi was swati . I may be wrong as already have posted , she is somewhere related to Swati and knows about Shalok, likes ,dislikes . She must be attached to her like elder sister . She knows only Swati,s truth where she though Shalok betrayed her and here Shalok thinks Swati betrayed her . So there is misunderstanding where none of them may be wrong but only became pawn in Niranjabn,s game . I just feel may be Swati is no more and Aditi is medium through which she is appearing as bride and Shalok may be secretly planning to marry her , niranjan came to know and swati was last time left at the alter .
Without finding the motive , can not judge Aditi .
Yes Astha is trapped here . And what i wrote about movie , i liked the idea where she did not was crying over that guy , yes she used to remember but then found herself . Astha is from a family which has strong ties . She thinks that she can ease out Shalok from this past but is ridiculed at every step . CVs shows just seconds glimpses thinking that to be love and with BG music . Is there anything else there .
