Barry: Would you escort Lois Lane here back across the police barricade and make sure she stays there? Referencing the famous comic book reporter, who first appeared in Action Comics #1 (June 1938). This tough-as-nails journalist works for the Daily Planet and has been Superman's long-time love interest. In more recent years, Superman informs her of his secret identity as Clark Kent and they are married. Barry's comment suggests that Lois Lane is a fictional character, meaning that presumably Superman is a comic book character in The Flash series setting rather than a fellow superhero.
