They are totally in a fix with Jiya needing break. That might probably be the reason they were aiming for ThaRab separation rather than keeping them together after their participation in the Janam janam wala puja. The spoiler s mention she was hospitalized more than once. So that and the need for leave must have brought in the need to reroute the storyline from whatever they had planned.
Viewers scream for ThaRab, yet who would want ThaRab that doesn't have Jiya??? It is a no win situation for the PH.
Now if they keep the Dargah scene real, they need to plan another Damaka to separate ThaRab coz there is no way fans will accept the new actor romancing Purab, when they waited do long to see Aakasya as ThaRab's khullam khulla romance.
But if they keep Dargah part dream, again fans will pelt them with angry words😆. And they have pulled down Purab from his pedastal. But separation is possible without another damaka and they could make it look like Taps left before the marriage that didn't happen in reality. Purab can be lifted back to the pedastal if it is made to look like he was making Taps go through the pain of rejection in order to protect her from further humiliation and Han's harmful plots. The marriage was his plan to expose Hans... Or he had just intended to distract Hans by saying he would marry her but things got out of hand when VD and Anjali joined hands to bring about marriage at top speed. There was no way he could avoid it without making Hans suspicious.
I think the best option for the PH is to face the viewers and address the issue. Reassure them that Jiya will be coming back and the replaced actor is temporary. To accommodate this situation they are tweaking the story and ask the fans to be with them in this difficult situation. Pull in Aakasya too in the conference. Deal with the situation in a mature and logical way, rather than put the fans in a defensive mode and leave the show.
