Spoilers ahead for Episode 16 of Supernatural Season 15, called “Drag Me Away (From You).”
Only four episodes of Supernatural are left before the final credits roll, and “Drag Me Away (From You)” delivered some twists that could point toward a major character dying not in the fight against God, but before the showdown even begins.
And that is especially bad news for Castiel.
Billie dropped by the middle of a case that took the Winchesters on a blast to the past, and her conversation with Dean revealed that she could pose as much of a threat to Team Free Will 2.0 as God at this point.
