I can only see one way in which the whole mess can be solved, that is dk's perception that disha is the cuprit and not pari, and mahika behing in love with etc......
dk oor better disha somehow has to manage to open kanchan's file and discover the real culprit
mahika's husband has to come back, she probably won't want to go back to him and in panic would come into the seghal house and threaten reveal everything to the evil trio, that he is dk and not satvivk and etc.....
dk asks her to keep quiet, but disha who came to tell him everything heard it all ( that he is dk), she is confused so does nothing for the present moment
she goes to kanaka, where the evil trio is chatting about how they should kill satvik now that their job is nearly done (she still does not know who satik is) she wonders who satvik is, and then she hears gargi say: that satvik is such a good actor, sometimes i feel like he actually is dk, she then gets everything...
to be sure she quietly leaves the place, and goes back home when sees aaroh and she's goes to him and asks him, hey what u doing here all by urself? he replies, i am just waiting here for my mom and dad
she is confused? who is ur mom and dad? he shows her dk and mahika. disha is shocked and she too in turn wants revenge
i wrote a lot know, it's like a short account of what may happen.....
