My guess

I guess Iccha is going to the old man as requested by the stranger and this man is actually Rathod's father. So now Iccha is unknowingly pretending to be Tapasya, so getting her life.
while tapasya will now be married to Rathod but will be hated by daima. Rathod might die so she could have to live life of a widow or if not then daima will continuously be scheming for their break up. But i think rathod will support her as long as he lives so that she can understand the meaning of love in spite of problems.

Iccha's story is going like tht movie "kati patang"...please CVs spare us from this torture...there's something called graceful ending...nowdays CVs do not end the shows they keep on dragging it until viewers get fed up then apruptly end the show...why do they do this??
