The showdown between good and evil is at hand and Dean tells Sam that he's decided to take part in the plan to bring down the evil.
A scene from the season finale of "Supernatural" is clipped. Dean tells his brother Sam that he's in for the big scheme to stop the Apocalypse. Sam and Dean realize they are out of options and make heart-breaking decisions that will change their lives forever.
"We're leading up to the big Death Match between Lucifer and Michael, which would cause the destruction of half the planet," producer Sera Gamble said. "Sam and Dean, of course, are trying to throw a wrench in the works, but these are the most powerful beings they've ever been up against, so their odds aren't great."
"Sam comes up with an incredibly risky Hail Mary to defeat Lucifer, which involves spending some very creepy, violent, one-on-one time with the guy. Terrible for Sam, but pretty damn fun to watch."
"Swan Song" airs May 13. According to the synopsis, a beloved character faces death and E! said it would be an archangel.
