All scientists would know of Mr.Right as he's used to finish up a job if the humans can't finish it. Werewolf won't turn? Call in the dark fairy who can make the werewolf believe it is the full moon.(course this wouldn't be done to any player controlled characters) Scales not coming off? Call in the dark fairy who can pull them out with his claws or use multiple tools at once.
Very useful he is. Basically like a back up tool to get their ingredients while he gets the bonus of food and such.

Shorter answer: no he isn't a secret.

As for being with the shape shifters I see no problem with it as long as you discuss the details with the person whom owns Hal first.
