I think the baron knows how to control a Zombie, and they would want to control Nick. Grimms have worked as killer for hire for royals before, so there is a history of royals controlling Grimms. Nick might be an unwilling puppet, but in Zombie state he has not many choice I suppose. And he is very powerful, maybe they will use him as their puppet, or can use him as a leverage against both Sean and his mother as well as maybe laufers.
