Wallace confirmed he’s “working on it,” in regards to a post- Arrow appearance by Mr. Terrific, though pandemic protocols may punt Curtis’ return to late in the season or possibly next season. That said, we already have David Ramsey’s Diggle coming back for multiple episodes across the Arrowverse this season, so it’s nice to see the creative teams are still keen to keep some of these characters around even without their mothership series. "I'd like to see him, not just as the character, but I'd like to see some T-sphere action taken to the next level,” Wallace said. “You get a little bit crazier and comic book-ier. I don't know how soon we can do it. COVID has shrunk our season, so unfortunately a lot of those plans have kind of gone out the window. So I don't know if we'll get to it this year, but yes, that is on my to-do list."
