The background characters seen at Arkham Asylum at the end of this issue are members of the Legion of Super-Villains. Their presence here is uncommon as they typically operate in the 30th/31st century. Dream Girl made a cameo appearance in the epilogue in issue #1.
Jeff Graves appeared last in Justice Society of America (Volume 3) #1. His colleague, Trey Thompson, was brutally murdered by Catalyst in issue #2.
References are made to Commissioner Gordon and the Bat-Signal in this issue.
Although Tom Bronson assumes the name of Wildcat in this issue, he actually first appeared in his were-cat form at the end of issue #3.
