Well, first off, as we heard, her kingdom hasn't been winning lately over the years so some people would respect her less along with her husband going to war and her being in another place other than her kingdom
Even royalty must be held accountable for crimes she is innocent in this case but if she wasn’t the system would be terrible to simply let her go for being the empress
Even though she's an empress, their country is most likely below than the other countries. So, other higher country citizens try to humiliate her because they have the protection of the other royal family (the high ranking countries)
Still up to now, I strongly disagree and was disappointed on how an empress, the mother of the land, being just easily being shouted, being pointed by a finger of a lower rank person, being accused, dragged, attacked and all. Why??? She's supposed to be powerful and feared or respected. Even though there are already persons who are addressing her as "your highness" or "empress" why are there still easily shouting at her as if she's lower than those people??? Its as if she is a peasant!!!
