You know how stupid that would be of him? But don't get your backwards thongs in a bunch if it IS Mason in the end anyways, I don't see ANYTHING wrong with it. How would making the beast be anyone else make you happy?

The promos released after the episode pretty much confirm that he is the host of the Beast.
