I was hoping Crowley would be protected by his status of main villain (of two seasons), since, shortly after the death of Abaddon, the show seems to have gained an aversion to killing main villains. But this doesn't apply to reformed villains, unfortunately for Metatron who could have become our new favorite ally of Sam and Dean if he'd lasted longer.

Though I hope you're right that these two characters are safe no matter what
