As I recall, Nick, Monroe & Co. couldn't determine for certain if Krampus was wesen, so they decided to turn this sticky problem over to the Wesen Council! If Krampus is wesen, he's certainly a very different kind given that his human "host" is unaware of what's happened during the whole time Krampus is "out" and apparently has no family history of this special problem to inform them, unlike typical wesen who are fully aware of what happens around them when they are woged.

So they left us with the mystery, and the Wesen Council just isn't sayin'.... ;)
