That's good, at least.
This whole situation is the most confusing thing that has ever happened to her and she needs to figure out how much danger she's in. There are people, she knows, who would kidnap an autumn equinox, and drug and hurt them out of revenge. Even though she's not grown up and hasn't done anything that was really bad instead of mischief. In that case she's supposed to abandon all propriety and let herself cry and do her best to seem like a normal kid. But...
The monster (which was a real monster, even though monsters aren't real, but the child here thinks they're real...) clearly got several people who she knows weren't her geminis. So this probably wasn't a very targeted operation. Unless someone drugged her to make her see that, even though it wasn't real, and it knocked her out, and they moved her, and then they had a way to wake her up very fast while she was standing up.
It's strange, if this was a kidnapping, that they put her with another child. Maybe it's a test? It doesn't really make sense as anything other than a test. Maybe they want to see... she's not sure. Whether she'll start acting bossy and superior to someone her own age? Especially since he keeps saying she's wrong about basic facts...
But if the monster was real, then what does that mean. (She really doesn't feel illucid - except for all of the things happening around her that don't make sense -)
...She got taken away to a place where monsters are real? Which means that a lot of things could be different... Like people not understanding astrology, and calling Latin something else.
She needs more information. She gets out from under the bed, fixes her hair and clothes as best she can without a mirror (which is something she has a lot of practice at), and comes back out of the bedroom.
