Rita looks up and takes a moment to study his face. She's not supposed to talk about magic with ordinary humans... but if he works here, with magic happening right under his nose, he's probably not completely uninvolved. Assuming he's not just playing dumb, he might have a right to know... if he's willing to listen, anyway. There's always the chance that Rita will just look even more like a crazy person.

"About the magic in this collar," she answers simply, after a delay. She keeps her voice low enough to avoid drawing the attention of anyone else in the room. "Must've been crafted by a magic-user of... well, a decent skill level, at least." The spell might not be all that advanced, but it has a sort of elegant simplicity to it, at least in Rita's eyes.
