After reading most of the comments here I wonder if I am watching the same show! As I feel that Izzah made it clear that she has a self respect, and knows how to deal with Altamash. She is fighting her liking for him, because he came from the world she vowed not to be linked with. She said it clear that sometimes a person has to make a wrong step to correct a wrong thing! so she knew that she promised her father not to meet him, but she was also keen to make her name clear and avoid being linked with Altu. and she knew only Altu can make sure no one links her name with him. and that's exactly what he did !
