If they were getting married I think Hania would have had more scenes in the ost. It's not that she was a surprise or something. Also, if the marriage actually happens it would effectively close all doors for Faazi to even consider Meenu being capable enough to be his wife. She would be forever compared to Saint Hania. Maybe if it had been a drama airing outside of Ramzan, this would have a very real possibility but seems too serious for a Ramzan series.
