[@TheMinorFall] I"m debating slapping him.  x.x  He just did something to her without permission, and touched her without permission, both serious breaches of etiquette.  ...How badly would that turn out?  I can turn it into her simply giving him a lecture.

And you've got a point about Primm, though part of why Amune is in her care is because I came up with the need for a chaperone and an idea for one before I set up the school.  Now to make an IC justification that makes sense and doesn't seem completely careless.
