Another year, another season of 'Supernatural' racing toward its inevitable endgame. But where previous seasons have put Sam and Dean Winchester, or even the world at large in jeopardy, this year it's angels, demons, and Sam and Dean's various saves over eight seasons on the line. Last night's "Clip Show" began the massacre, but will our main duo strike a deal to keep everyone safe? Watch the latest clip from 'Supernatural' season 8 finale "Sacrifice" to find out!

Sam and Dean may have a bead on the third trial to close the gates of hell, but Crowley won't make it easy for them after last night's episode, using the writings of Carver Edlund to track down and kill all their past saves. Next week's season 8 finale "Sacrifice" will see Sam and Dean ultimately looking to make a deal to spare more bloodshed, as well as hand over the demon tablet, but will Crowley underestimate the Winchesters' plans?

From the official CW description of next week's finale "Sacrifice":

WHAT MUST SAM, DEAN AND CASTIEL SACRIFICE TO FOREVER SEAL HELL? — With Crowley (guest star Mark Sheppard) poised to undo all the good they’ve ever done as hunters, Sam (Jared Padalecki) and Dean (Jensen Ackles) find themselves cornered. But with Kevin’s (guest star Osric Chau) help, the Winchester brothers bound into one last play against The Demon King. Metatron (guest star Curtis Armstrong) initiates a plan with Castiel (Misha Collins) to take on Naomi (guest star Amanda Tapping) and the bureaucracy of Heaven.

So, what do we think? Will one, or both of the Winchesters end up making a “Sacrifice” in the finale? What do you hope to see from the final episodes of the season? Check out the first clip from ‘Supernatural’ season 8 finale "Sacrifice," and give us your predictions in the comments!
