Not to venture off topic, but Charmed went pesky humans, group of weak demons, source of all evil, Strong elder and Strong demon, Rival to the Source of all evil and serious humans, then a group of power beings. Supernatural went ghosts, demons, angels, leviathans, the Darkness.

So, I'm guessing they are bringing something with them, perhaps unintentionally.

Unless this season has a happy ending...
