I know that this is late, but i finished all my playthroughts up until version 3.1.8. And i found it really odd that Hana never commented anything about Azar when she joins in the minotaur cave.
Is strange but compreensible that she wouldn't say anything in any routes other than the blood mage, but there's no comment whatsoever. And from what i gattered about Hana is that she is full of herself and she is possessive. She seemed to really dislike Azar too from what i read in her voice lines. It's really strange and even unsettling.
