Jack Dupre

Jack Dupre was a magican who conducted a ghost walk from 7pm onwards in New Orleans. Jack followed the Eighth Doctor when he was touring a museum. When the Doctor was alone, Jack knocked him unconscious. He tortured the Doctor in an attempt to summon a demon from within him. Jack was shocked to find that the Doctor was an alien. Jack summoned the Demon from the Doctor and created a magic circle using Graveyard dust to protect himself from it. The Doctor blew some of the dust away and broke the circle. The demon ate Jack.
