This was a good development. No, she wasn't being sarcastic because of all that had happened: the meeting on Miracle Mountain that led to the slaughter of King Ameal and his people, the aftermath of which resulted in the destruction of her city, the ensuing battle between Knight Boris and Grand Duke Liam, and now the death of King Bor and his army of assassins - all of whom were murdered in the middle of the night by a pirate.
Okay, maybe she felt a little sarcastic, because even with all her efforts to unite against a common enemy, the fact that they ended up killing each other or getting into petty arguments was maddening.
And all this had happened regardless of the fact that she took a much more peaceful approach, only exerting her authority when needed. Yet, chaos seems to be the anthem of the week.
