Something fun I noticed this episode is that while Occtis has reached a point where while he openly acknowledges that Primus is dangerous and actively malignant, he's still thinking about this as purely a Primus problem, rather than noting Primus to be a symptom of a broader systemic issue with the Sundered Houses. When the whole table is discussing the possibility of the Sundered Houses colluding to do something during the opening of KoTher'ai, he's the one who offers the theory that it might just be Primus going off book and behind the backs of the other Houses. And he does have reason to think this! His sisters in their letter to his uncle pretty plainly complain that Primus is doing things without consulting other people and neglecting political concerns to focus on working whatever great work of magic he's cooking up this week. But it stands in stark contrast to the perspective that some of the other PCs such as Murray bring to the table which is that the Sundered Houses as a whole are a problem and that even if it's only House Tachonis that's plotting something, the others are still complicit.
Occtis not seeing the Sundered Houses themselves as an issue is something that's been borne out by what we've seen from him in the whole campaign so far. He is, even of the noble PCs, the one who is the most comfortable with throwing his family name around in order to try and get what he wants, as seen during the fight on Hacvallen Brücke. His request that Julien let go of Thimble's wings back when the three met outside Hal's house was framed as an order. When talking to the other PCs he, in spite of his family outcasting and murdering him, still refers to Seremai as one of his vassal houses. There's an assuredness he has about his place in the general social order that makes it clear he's never really thought to question it, this power and station is simply his birthright and he's going to use it. There's also the broader concept of the fact that people are less likely to question the legitimacy of systems they benefit from, and Occtis has benefited a great deal from the social order of the Sundered Houses being what it is, as the power and wealth they hoard is something he as a member of the in-group has access to. And he clearly sees the fact that he does have access to it as simply the natural order of things, it's always been this way and much like the people-cages he's never thought to question it because it's always been that way. Compare that to characters like Murray and Azune who've known poverty and long felt the boot of the Sundered Houses on the collective necks of the common people, and thus are far more aware of where the entire system is unjust.
And the result is Occtis having a much different angle of approach towards the problem of what his family has been up to than a lot of the other characters. Rather than seeing what House Tachonis is up to as the workings of a corrupt and harmful institution trying to uphold and gain more power by any means necessary, he's purely seeing it as an issue of: "My dad sucks." And while that isn't an inaccurate assessment of Primus as a person and a parent, it does lose a lot of the nuance of how he's able to be as much of a problem as he is, which is that he's being enabled by an institution that strengthens itself on exploiting others, and Primus has just taken that to the logical extreme.
