"Nightwing's" 100th issue is rumoured to be his last (though not officially confirmed as such). This has caused a number of people to see it as proof of the rumour that he's the killer from "Identity Crisis." He also follows the classic murder mystery trappings of appearing in the first issue, with a similar trenchcoat worn by the killer, and all the deaths start on the anniversary of his parents' own demise.
