Rosh this makes a lot of sense! Maybe we are a little crazy to be so optimistic but this theory explains a lot!
How stupid can Gul make her lead AAK look. Plus there has to be a reason for Mangalpur part 2 before Ajmer right. I mean why have this scene. Zoya is not in the house but still Billi is trying to kill her and Asad will save her. This has to have some significance.
I really hope you are right and Asad starts understanding Billi. I really hope so. Today he cursed billi. That was interesting too. Until recently, we all thought, he would be the one to expose billi (Bheegi's-kheer symbolism). Maybe its time.
Perhaps some of the Ajmer confrontations is when Asad is also trying to tell Zoya about billi but Zoya does not listen and Asad goes in Tadap Tadap mode. And then we have the Billi Zoya confrontation. I strongly feel we will have a cliff scene. There has to be scenes which we don't have any spoilers/segments/pics of in Ajmer right. I mean they went so far to shoot, I am sure they concealed something. So I feel during the cliff scene she will try to kill Zoya again (because she probably blurted the truth to Zoya during the confrontation-just like Raziya blurted to Badi Bi) and Asad will come in time, slap Billi and save Zoya. There is no way billi is winning in God's place.
This is when Zoya will start to feel guilty. They will go to the dargah and finally reconcile/get married there.
Honestly, if Asad is committed to marry billi then i don't see him ever confessing to Zoya. That would be further breaking her heart-it's not possible!
Let's hope Gul is in to surprise us!
