I get where you're coming from, but what is she supposed to do, it's not like she would be of any help if she went with them, and she gave him instructions on how to get out, so I'd say she did all she could to help honestly.i hate the type of character the supervisor is. there seems to be one in every manga/anime and they're beyond annoying. they have some sort of power, whether it be in skills or in a "work" position and they just do jack-shit of insuring the safety of those they have power over.
