Okay, but what's the end goal here? She already knows that if she assassinates the 2nd prince, she'll just be made a scapegoat, so what's she sneaking around for? To locate the anti-emperor count and question him? But even if she questions him, he'll just tell her stuff she already knows, the emperor is a piece of shit and he'll betray you. It feels like making allies and collecting evidence of the emperor's plans to violate the peace treaty should be more important idk
Has she even told her subordinates that she's anti-emperor now, or do they still think she's planning to assassinate the count?
