Jesse Rath (Agent Riggs) went on to play Brainiac-5/Querl Dox on Supergirl; Andy Mientus (James Finley) plays Hartley Rathaway/Pied Piper on its sister show, The Flash, set in the same universe.
While the show is based in Pittsburgh, Pennsylvania, the characters travel throughout the US to solve kidnappings. The final showdown in this episode is filmed at Century III Mall, a condemned former shopping mall in the Pittsburgh suburb of West Mifflin, but the scene is meant to take place in and around Green Bay, Wisconsin.
