As far as Cooper's role on the Night Council goes, he's very intrigued by this idea. Personal bias against the fae, considering what's happened to him in his past at their hands, are definitely going to be coloring his opinion. Also, having dated a witch who was part of Midnight in the past means he's more inclined to bend the rules in terms of what is considered to be dark magic.

But, considering that the vampires only just got their position back on the Council and are still sitting on a precarious perch, he's going to be having a long discussion with Jean-Claude first to consider his opinion on the matter.
