'Supernatural': Meet the Leviathan... and don't drink the water
As legend tells it, God created Leviathan before he created humans or angels -- and they were so dangerous, he had to create Purgatory just so he'd have a place to lock them up. Now that Castiel has set them free, the Leviathan are having a fantastic time on Earth. Basically... we can expect them to treat our world like it's Charlie Sheen's hotel room.
In a lot of lore, the Leviathan are sea monsters, so it's not much of a surprise that one of their first acts of delinquency is to slither into the water supply. We love the newest promo, which starts off like your average local commercial... and then gets gruesome.
Tune in to Episode 2, "Hello Cruel World," on Friday, Sept. 30 at 9 p.m. on The CW. It looks like Sam finally comes clean to Dean about his Lucifer hallucinations... if they are hallucinations.
