He is a famous magician appearing at the main event.
Background
He is famous for doing magic tricks while feigning demon possession. He is also very much stuck up and self loving. Sam and Dean see them when they come to investigate the death of Vance. Jeb is also the highlight of the Magic Event. Later on, he interviews Jay for a television special, but keeps calling him the wrong name (Jay's friends call Jeb a douchebag in the background). As he is preparing for his next show and checking himself out in the mirror, a cord comes down and hangs Jeb. Jeb dies in his hotel room.
