I think this is how it might be..
Shivaay first assumes Pinky told a lie to Anika about his NKK (here in Shivaay's NKK will re surface...he wont believe that he is Naajayas...he will believe that pinky lied to separate them.)once again the NKK conflict in Shivika will rise...(has to)and after a lot of drama Shivaay will realise the truth and leave Oberoi Home. (The vanvaas)And after all this we get to know kamini ne sab ka pappu banaya!
