I can. Their infighting is their signature trait, at least in one another’s company. But it does suggest that they are capable of functioning in a professional capacity while their close colleague is one who constantly challenges and rejects their suggestions. As they are constantly locked in this feud, their motions are actually far more functional than those from the more corrupt nobility. Neither one walks away fully happy, and so, the most needs are met for the population at large. They understand this, as they have never sought to resort to subterfuge or conspiracy to have their way.

At least until my father and the Prime Minister approached them for the Insurrection. They may have been able to stand against one or the other, but opposing the two central figureheads beside the throne was tantamount to signing their own death warrants. 

Not high, I assure you. Regardless, it’s vital to review how Those Who Slither in the Dark have manipulated others.

They prey on existing delusions of worth and glory, as they did with Ludwig, or they target trusting natures and uncertainties about society, as they did with Christophe. With so many centuries between my time and the original incident, along with extensive rewriting history and censorship, it’s impossible for me to say which is the case for Nemesis. It’s not impossible that he was told just enough information to send him into a vengeful rage against Sothis. That appears to have been their method in convincing Dimitri that Her Majesty was behind the tragic events that claimed the lives of his family and close companions.

Who would you say was (thus far) the most frustrating to deal with? Whether they be a true danger, just annoying, or those traits and others.

I have indeed. Naturally, there are occupants of Fódlan’s underworld who are closer to unseen sentinel than seedy malcontents. 

The most frustrating by far on all accounts would be the former duke and prime minister, Ludwig von Aegir. He's had his dealings with the underbelly of Fódlan on several occasions. 

A great deal of my frustration with him finds its origins with Her Majesty’s request to put him on house arrest in the interest of safeguarding Ferdinand’s softer feelings for a man who, by some cruel mockery, happens to be his father. It would bring him sorrow to have him dead. As such, he yet lives as no small source of irritation and posturing when I do find myself in his presence or receiving yet another missive that he must know is not reaching Ferdinand in full, if at all.
