Is it just me ou does anyone else think Crowley might not be a demon? If so, what do toi think he could be?

Interesting question Moriah - What are toi thinking he is then - a fallen Angel like Lucifer? Is that why he gets on so well with Cas as they're really brothers??? Whatever he is - I l’amour him :-)

he is the devil

There is a theory that he is a fallen Angel, because he a dit he had a thing with Hannah in Mesopotamia. People think that he may have realized it when Sam was pumping him with humanity.

He has to be a demon, because they've shown parts of his human life before he died and went to Hell and became a demon. His son, his mother. Those rule out any theory of him being a fallen angel, anyway.
