Constantine may have been canned but the master of the dark arts has been resurrected courtesy of a guest spot on Arrow. John Constantine will feature in an upcoming episode of Arrow S4 as he journeys to Starling City to help out Oliver Queen. The official synopsis reads:
When things take a turn for the worse with Sara (guest star Caity Lotz), Oliver (Stephen Amell) calls in a favor from an old friend who deals in the mystical, John Constantine (guest star Matt Ryan). John Badham directed the episode written by Brian Ford Sullivan & Oscar Balderrama.
Chances are Constantine may well assist Oliver in exorcising a demon or two, which may have come back when the Canary was brought back to life in the Lazarus Pit. Of course, fans are hopeful that this appearance could lead to something a little more permanent for the master of the dark arts. In the meantime, check out the teaser for the episode titled ‘Haunted’, which will air soon.
