Supernatural Season Finale Trailer: The End is NowMatt Richenthal at .
The end is now.
So the trailer for next week's Supernatural season finale teases below. What, exactly, does this mean?
We'll have to tune in to find out, but we can forecast that Sam and Dean must make certain choices in in order to prevent the Apocalypse - and that a veteran character dies. Who will it be?
A certain Tweet gave us a hint, but we don't wanna believe it. Watch the following promo and get excited (and nervous) for next week's "Swan Song."
