A lot of interesting information and surprises buried in this. I think one of the biggest is simply that we now have a firmer sense of how long the Shadows House has existed and timelines. Assuming the "3rd Floor" are all first generation, or at least the first successful generation if there were "prototypes" that didn't work while GGF or whomever figured the process out, then it's only been 30-50 years maybe since the fall of the Mirrors. That fits in with guesses based on the apparent aging of Kate's mother's attendant but still good to have a harder number. It also means that fundamentally the Shadows House including the "Adults" don't actually have that much raw experience yet, there is no one who is like, 80 years old or something. That ties back in with Kate saying she doesn't think the SH system is "perfected yet", there are holes in their net. Candy is even more of a potential resource than I thought, the first real actual adult of any level who may be fully on the Children's side and can give them a ton of different perspective, plus on top she spent decades in the greater world which is possibly pretty unique even amongst the Shadow and island adults period.
On the immediate plot, Edward clearly overreached. He did do some real investigation, though he's still missing key facts and players, but his ambition and indulgence in his own sense of cleverness and ladder climbing efforts are also clear and a weakness. It may be how they're raised, but politics is an interesting blindspot for him.
Definitely really cool cover. Guess we're now heading into the real crunch moment with Lou & Louise, and Anthony still lurking in the background of it all completely quiet. The wheels continue to spin faster, all the build up is quite something.
Scariest possibility I can imagine is that they don't care about doing an investigation because, if the children become troublesome enough, they are willing to just eliminate all of them and start over, not caring who the "troublemakers" are.
Of course? This has always been the big guillotine hanging over everything. The adults have such confidence in the awesome power of brainwashing, their whole system, and their isolation, that they've got huge blind spots to covert operations; they've never needed to really think about counterintelligence or infiltration for example so they don't. But as was painfully demonstrated with Maryrose vs Edward, the Adults have had an absolute advantage in sheer, raw power, and the tactical situation is grim. The Children have no easy escape and are fully dependent on external supply to live as well. The Children's House is a pretty well designed prison, albeit a luxurious one. So there has always been the balance, as long as they operate in the shadows (heh) they can do a lot under the Adults' noses, but it doesn't change their core situation either. At some point they need to take open action, and at that point it's a direct fight. And the runup to that is insanely risky, because they're necessarily doing more and more "strange" stuff that could get them exposed, but aren't actually ready to fight directly either.
And most if not all of the Adults are clearly perfectly loyal to the GGF and overall system if not each other and utterly ruthless as necessary. I've never doubted they'd wipe out all or most of the kids and start over again if threatened enough, they've got plenty of new "stock" and spending another decade or two building back up with more safeguards in place wouldn't bother them much.
So remains a very tight balancing act for rebellion. Kate probably only gets one shot.
