So I just went back through the story in reader mode searching "Monica" and I'm finding her sudden certainty of QA's royalty in this chapter strange. There is only a single reference to Monica thinking of QA as Hell royalty.
I feel like it's a bit of a stretch to go from "Taylor might be eldritch royalty" to apparently absolute certainty that Taylor is a princess of Hell.
I'm going to guess that intervening interaction has somehow persuaded Monica that her offhanded speculation is fact, but it's hard to say exactly what has made her so certain. Did QA start smelling of fire and brimstone? Does Monica find Pegacorns blatantly satanic? Does she think 'magic' = 'infernal pact with the devil'? QA's mentioned extensive memory modification and a general 'survival of the fittest' mindset, but I don't understand why Monica has arrived at such certainty of "Hell royalty" instead of "cult survivor", which seems like the more reasonable choice.
Anyway, apart from that, let's see if I can understand the rest of the chapter.
Going to guess Anna is busy exchanging high-band info with Silver, possibly regarding Taylor, Rose, or maybe just tech in general. Going to also guess that Anna is trying to figure out where is the most defensive place she can put Silver when carrying her into battle. Can't leave Silver on the ground of course, or Antagonists will get her. Having her near Anna's body is obvious the safest, but the question is, where can the pegacorn cling so it's not in the way, and Anna can defend it? Bet that Anna is remembering all the times an Antagonist shot off or shot at various parts of her body which is why she can't determine the safest part of her body to put Silver.
Nyx has been so encouraging to Monica, it's a shame she's not got the processing to understand Nyx's communications yet.
So... I think what happened here is that QA's Friends with their hat powers have kinda majorly twigged some Valkyries' PTSD buttons by being way too similar to Antagonists. There might have been some actual Antagonists with that kind of sensor-spoofing powers and the UN is apparently hoping they're not real? Either way, I think Kaiti is encouraging Taylor to go to therapy sooner not necessarily because Taylor needs therapy (though she does) but to get her out of a volatile situation before Valks can get itchy trigger fingers. Also to remind said Valks with itchy trigger fingers that Taylor is not an infiltrating Antagonist, but a regular human who needs help and therapy.
Not sure if I got all this correct, but it's my best guess anyway. I look forward to reading the speculation of others!
