In the last scene when all the angels were cast out of heaven all of you commenter do realize that not only Sam and Dean saw the angel being cast out of heaven,but evey human worldwide also saw the angels being cast out of heaven, that would mean that in the next season, that all humans on earth will now be aware of the supernatural.

So that means next season not only do Sam and Dean have to help the angels get back to heaven, stop the demon from taking over the world, stop the old gods from regaining their power over humans, and stop monsters and ghosts from causing choas, they now have to deal with the fact that all humans on earth will now know about the supernatural.
