Guy who works the government office in Nucleus is a hell of a type of guy. Like, first of all, you have to have the disposition both to like the culture of Nucleus—in fact they want people who deeply appreciate it—and to be good at being a very highly reliable worker. But beyond that, well... most customer-facing workers will eventually end up with some interesting stories to tell, sure, but generally you won't quite have been the person responsible for actually dealing with them? But the government office is meant to be reliable, in the sense that it's rather unlikely to just kick you out. Unless you start doing property damage or harassing people who dislike it, or something like that, and can't be quickly talked down.
More often than that, though, you've gotta deal with someone who's going through a hell of an ontological crisis and who has started being confused about the role of the government in the universe, or something. Which like, valid, the particular office in Nucleus may really just be a handful of unusually skilled people, in the end, but it does in fact act on behalf of Providence to an extent, and Providence is a sensible thing to have some deep questions about? Like, if you work for a government office in Nucleus you have spent a hell of a lot of time thinking about what that means, given that it is one of those cities where lots of people will very much not just go along with whatever the big powerful outside force asks of them if they don't thoroughly understand the necessity. You're gonna be much, much less likely to settle for a simple handwave-y answer than most.
So, y'know, they've been interrogated by people who are deeply confused or have a new galaxy brain philosophical perspective or are somewhere between the two, a few times. They're competent to provide basic grounding info if it looks like that would be helpful. They are not actually read in on every piece of secret info which some random Nuclide would plausibly piece together, exactly, but they're read in on the classes of reasonable guesses and are familiar with the glomarization policies. They keep up to date on the sorts of pranks and other assorted shenanigans that might end up with them wanting to be prepared for a very strange conversation, to the extent possible. They can recognize all the troublemakers, save those they're kept in the dark about for decision theoretic reasons (as sometimes "when would the officers piece it together if not told" is the sort of fact Emergency Services wants to know.)
Anyways, the point is: they occasionally see a situation actively optimized for being as confusing as possible. They aren't, like, the Emergency Services group that you get forwarded to if you're making incredibly-weird-but-testable claims, but the Celene situation isn't going to throw them off.
