No as per yesterday's episode Aaraina herself was telling Shashank that she came back to Delhi after five years and Delhi is the place where she lived throughout her life..so this indicates that Aaraina went abroad only five yrs back when she was almost a adult..so her childhood was spent in Delhi only and Aziz too was there in the same house because again the synopsis says sinse childhood Aziz was fond of Aaraina😕😆 So u r right..we need to keep our brains in some refrigerator or freezer while watching BT Soaps😆😆
i too thought about that but then there is possibility that ...Araina's parents must have sent her abroad with in say about two years of adoption and may be after the two years Aziz and his mother joined the family .....all these are possibilities me too not sure ....only ekta maiyya knows the asli reason
or it may be the other way round like Aziz was kept away from his mother for some reasons...but i m not really concerned bout it i know i m watching a K soap after all ....have already kept my dimaag in the refrigerator. 😆
