|Episode(s)||15.01 Back and to the Future|
Look, I'm not some crossroads demon. I'm not even one of those black-eyed goons who crawled his way up here to eat, you know, virgins and puppies and virgin puppies. Look, downstairs I punch a clock. A soul comes in, I torment it, it's what I do.
– Belphegor, 15.01 Back and to the Future
Belphegor is a demon who was released from Hell when Chuck opened all the doors. A self-described "clock puncher," Belphegor enjoyed his work punishing the souls that entered Hell and wishes for things to go back to normal after the mass breakout, offering his services to the Winchesters and Castiel.
With the Winchesters and Castiel trapped in a crypt, Belphegor makes his presence known by taking possession of Jack's lifeless body. As he tries to formally introduce himself, Castiel, angry that he is defiling Jack's body by possessing it demands that he leave. Do to their desperate situation, Dean and Sam allow Belphegor to explain himself. He tells the Winchesters and Castiel that he wants the souls back in Hell as much as they do, and offers to get them out of the crypt by performing a spell using graveyard dirt and angel blood that blasts all the souls from their meatsuits.
Driving back to the Bunker, Belpehgor reveals that 2-3 billion souls were released from Hell, and if they are unable to close the rift, containing the souls is their best option, offering to perform a spell that would act as a mile wide salt circle in Harlan, Kansas to keep any other ghosts from getting in or out.
In Harlan, Belphegor and Dean remain downtown to collect the ingredients for the spell, while Sam and Cas help evacuate the citizens. After getting a bag of rock salt, Dean and Belephegor prepare to go to the morgue to retrieve a heart for the spell.
