I think that wen in yesterday's episode Razia told Tanu to make arrangements for sending Zoya out of this country, I thibk Tanu ordered for those tickets in Zoya's name...
Now Asad wants to stop Zoya n will go with those tickets to her with the intention to stop her but Zoya wud misunderstand that Asad was in so much hurry to send her back that he even got the tickets ready!!!
I don't think that just in one night Zoya wud book the tickets n wud decide to leave just like that...m sure Razia n Tanveer r behind this ticket fiasco!!!
