71 parts Complete Cataleya is mysteriously back, but it won't take long to find out how or why.
Dean is wrestling with a confession he made, unsure if she feels the same.
And Sam is being influenced by someone/something he doesn't see as a threat.
The apocalypse is nigh, and the three, assisted by a few others, will do whatever it takes to stop it before it's too late.
But doing so will come at a cost none can fathom.
(Seasons 4-6)
