SUPERNATURAL | SEASON 16 - TRAILER (2025) Teaser Concept

SUPERNATURAL Season 16 – Sam Brought Dean Back... But at What Cost? Dean Winchester is alive because Sam brought him back. In this dark, emotionally charged fan‑made trailer, Sam Winchester, broken by grief, crosses a line he swore he never would. Desperate and alone, he performs an ancient ritual lost to the Men of Letters—one that fuses celestial magic with a forbidden pact. The result? Dean returns, but he’s not alone. Castiel reappears, emerging from the echoes of The Empty, warning Sam that this resurrection wasn’t clean or natural. New monsters are appearing—beings that defy everything hunters thought they knew, tied to the darkness that came back with Dean.
