It's also respect for the fact Holiday had felt it worth keeping to a select audience. Annie doesn't have the same divide on "Registered" or "Unsettled;" she can't afford to think too narrowly. It'd be too easy for her to get over-focused on one set of details if she did.

"Why none of the rules seem to make sense. People say one thing... like do this like that, because it's supposed to work that way. Then you learn there's all these exceptions, for no consistent reason. Or there's rules for parts of English no one thought to tell you about, because they forgot you wouldn't understand all the history behind the language."

Holiday felt everyone needed to know more. Trusting Registered was a peace offering - giving them something that people higher up hadn't wanted them to have. It's information, and nothing more complicated, but everything precious. What reasons to keep them in the dark over remnants of the more recent history of this world was there? Holiday had been part of the original group dealing with imPorts and the changing of policy in the United States away from the military state it'd been in the 1980's. Now he was gone, and Ananke had a gag order when it came to talking to imPorts at large.

Or something close to it, after the Hornets claimed themselves as real.
