I think maybe when B will find out abt tht his dearest Arjun actually our dearest Arjun was killed , than definitely she will sketch a plot to take revenge of Arjun's death from the evil 3, and in all this she will find A's humshakal who will turn out be the real Arjun, in last,and i think the doctor walia will also become the part of A's plan or whatever.😉
Wat say????, because i have this clue tht not for one moment they show Arjun's face
