Close to the end of the episode, they finally confronted the Mother. She told them that Crowley was still alive. And they deduced that about the only way that Crowley could still be alive is if Cass was involved somehow(Cass was the one that supposedly found Crowley's bones and "killed" him). Then we see from next week's preview that it looks like Crowley is definitely still alive and that he's working with Cass in some way. They're setting it up like Cass is a fallen angel doing shit for his own purposes.
