The dark fae would have more of a problem with it than the light fae would. Bo, herself, had practically claimed Kenzi as her human just to keep the girl safe in the fae world. If he had to do the same with Maria then he would do so. Hopefully that was not something that they would ever need to do. Something that he, himself, would never have to do.
"The stories are not always true but there is some truth to them." Every story has a bit of truth to it. "We have the light fae and the dark fae. I, myself, am part of the light fae."
There was another in Madison Valley who was part of the dark fae. Though he had no problems with Vex, no matter how much the man drove him crazy.
