My Theories

1. As shiv shakti plot applying more foreshadowing why do I feel Nawab shown full memory loss or partial memory loss just remember Heer name not her face. As when today Heer pray as she don't want to lose Nawab then moment Nawab shown missing another foreshadow and Nawab ka baar baar bolna main tumhe chodke kabhi nehi jaunga. So maybe Daler will attack Heer like try to shoot her then Nawab will come between her then he got head shot. Heer will be shattered and feeling guilty as hospital scene BTS came so Nawab wake up not able to recognize Heer then Daler or Gulab blackmail or make a deal with Heer to go away from Nawab forever for his well being and blame for Nawab conditions. Then shattered heart Heer will move on to Mumbai then came back after 6 months with new look new personality and Nawab will be shown with Shanaya aka fake Nimrat as both are in relationship (makers love 3rd angle) like Nawab Tina type not serious type then Heewab again cross the path and many hit miss scene will happen but one day Heewab will came face to face Nawab will shown more curious and shown attraction towards Heer as Heer will shown distancing for Nawab health and well being maybe change her name. In shiv sati story sati father humiliated and insulted Shiv just like Heer who is facing Humiliation and insults from Daler (present as Sati father). I know makers love Nawab getting beaten and Hospital scene more as he is FL and Heer ko ek kharosh bhi nehi aane nehi dega she is iron lady and ml for makers

2. Goons and Daler killed Heer by throwing from the cliff Nawab kuch nehi kar payega maybe Daler will trap him or distract him in somewhere else. Then Nawab will be shattered and more do some junooniyat and crazy stuff and still believe Heer will return. Then 6 months leap Nawab will show mature and shown him successful cricketer infront of the world but inside he is death and hoping for Heer return and where else Heer shown in rich loyal business family and her look and personality change and will get new identity as she will remember anything about Nawab. As CPU BTS came maybe Heer new family want business extend to Chandigarh maybe collaborating something with CPU then Heer will be shown in CPU.

3. Heewab will elope together after defeating goons and Daler and will move to Mumbai. Living happily together from Brar and Daler

I know (2) and (3) not possible. As Nawab (Sati) and Heer(Shiva) who gets humiliation. Nawab FL and Heer ML. So possibility (1) theory
