after rogi divulges the information on fury/denis to jack and dorothea, the remillard dynasty assembles in order to 'exorcise' denis. denis is tricked into making himself vulnerable, and they attempt to remove the fury element of his psyche. this goes disastrously wrong, and denis/fury vanishes. he is later realised to have "d-jumped" — teleported — a first for man and most aliens, although it is revealed in the saga of the pliocene exile that the shipspouses of lene had this ability.
