In the next "Supernatural", Sam, Dean and Castiel track down the Colt and head off to find Lucifer to send him back to Hell. It's a hunters' reunion when the crew joins forces with Bobby, Ellen and Jo for what could be their last night on Earth.

The episode is called "Abandon All Hope" and it will boast the guest starring appearances from Alona Tal, Samantha Ferris and Mark Sheppard. The first two reprise their roles as Jo and Ellen respectively while Mark makes his debut as Crowley. The episode will air on November 18 as the last episode of 2009 and the show is scheduled to return with originals on January 14.

Talking about the episode that will leave fans hanging, Misha Collins aka Castiel told Huffington Post that there will be a huge showdown between him and Lucifer. "Well, as with the Devil's trap, which is used to trap demons, there is, actually, as we've discovered on the show, Angel trapping technology, that I introduced to the show. It's a ring of holy fire," he explained.

"And Lucifer ends up using my own tricks against me and interrogates me, in a way. Basically, Lucifer tries to persuade me to join his ranks as a fellow Fallen. A fellow rebellious angel. It's quite a face off."
