Also, I don’t think I understand why the evil noble has to sneak out to give Myne a poison and give the kidnapper instructions himself. Is it a needless event to implicate the evil noble and Georgine or perhaps there’s a good explanation?

I did not reread that passage, but I believe to remember that there had to be a noble to knock out an arch noble. Even though she was a kid, Charlotte could have just crushed the fall guy. And if I remember the poison wasn’t poison but a drug that would keep someone’s magic in locked, it just so happens to be poison for the unique health condition that Myne was in. Grausam (name means “cruel” in German, btw.) really did try to kidnap and not kill.
