Vampires, wolves, shapeshifters, witches, and faeries not enough for you? You can expect an additional category of supernatural creatures to be added later on in season 5.

A spoiler report from E! Online says that it’ll involve Sookie:

If you can believe it, the HBO hit will actually be introducing a new supernatural entity later this season…and they’re taking a page out of the Vampire Diaries’ playbook: Sookie’s getting a doppelgänger! Here’s hoping she’s nicer than TVD’s Katherine!

Any theories as to what kind of supernatural creature this could be?
