Ennis briefly returned to the title in 1998 with " Son of Man " , filling the gaps between Paul Jenkins ' and Warren Ellis ' runs on the title . This more irreverent story is about the consequences of Constantine resurrecting the dead son of an East London gangster , using the spirit of a demon . He also had two specials published during his run on the title , the Hellblazer Special and Heartland , which follow Kit Ryan 's return to Ireland .
