One thing is clear from today's episode. Abir's baba was not an evil person. I have read a lot of theories on this forum stating that Abir and Kunal must be sharing the same father and he must have been a rapist. But from today's episode, it's kind of clear that Abir gets his philanthropic nature from his dad. I assume, his 'banjaraness' is blood related. In previous episodes, when Abir was shown to be talking about his dad with Meenakshi, you could see that he has trust in his father. He does not believe Meenakshi in the fact that his father left them because he doesn't love them. And I guess, that's why I don't think the makers will show Abir's trust broken in this truth being unfolded. On the contrary, I believe that Meenakshi must have had a brother who was a criminal and whose deed may have affected Abir's dad's household. Parul must have been Meenakshi's brother's wife. She must have gotten pregnant before his death. Due his misdeeds, Nanu's business must have been affected which Meenu had to take up later on. In order to not let Kunal get affected and be labeled as 'a criminal's child', Meenakshi adopted him as her own son. Abir's father must have not had a problem with this action of Meenakshi's, however, his family must have not accepted Meenakshi after this move. Hence, he had to leave them. This will be contrasted by showing that Abir would not be like his father. He will not leave Mishti due to his family and instead, he would not lead a banjara life. The subtle changes in his lifestyle are already visible like him getting a phone- changes which Meenakshi couldn't bring to her husband.
