I think it's pretty obvious she is, but as usual with this cluster of incompetents, she isn't a very good spy. Don't laugh when the target tries an obvious lie, you dumdum...The question is: is she actually an agent of some sort or is the author baiting us?
I agree fully with the sentiment but I think she's also referring to how Benika is a walking billboard with her personal informationShe threw falling glass at your agents and you think a spy asking such obvious questions is gonna fool her?
