What I think - based on the SBB segment of today, DB and Dolly will leave with Zoya. There are no direct flights to NY from Bhopal so they will have to go to New Delhi. I know that Ajmer is not exactly on the way from bhopal to Delhi ; but for the purposes of the story, they could travel via Ajmer (either a train that passes through Ajmer enroute to Delhi or by road.I very strongly believe that Zoya will meet with some kind of a calamity (train accident/ road accident) in Ajmer and DB will inform Dilshad and co. Remember the clause that in case of health issues, till the time the person recuperates, the person can stay in the country. This mention in Friday's episode must have been foreshadowing the actual health issues that Zoya will face!!Asad will go crazy and get to Ajmer and here I think he will confess his love NOT to Zoya but to Dolly - Zoya will be in the hospital battling life and death. Dolly will empathize with Asad and work on Zoya's visa extension... and the visa issue will get solved.What happens to Asad and Zoya after this, not too sure!! I dont think the Ayaan angle will take place at this point in time...For one, Zoya chose to stay back because of Asad; doubt if she will want to stay back in india after Asad asks her to leave! It will be OOC. Also, if Rishab is leaving or is at loggerheads with the PH offscreen, I doubt if they will start such a major track featuring him.
I like the theory and it's very plausible but forum 32 confirmed that they haven't started shooting in Ajmer yet. So , unless the scenes we saw on SBS air only next week I don't know how this plays out.
