While Rick Cosnett's Eddie Thawne had a small role during The Flash season 8 midseason premiere, the showrunner teases the fallen character's return for more episodes. After an extensive hiatus, The Flash is finally back following its big Armageddon 5-part event. While not a traditional Arrowverse crossover, Barry Allen was joined by various heroes from the other shows, including Black Lightning, Batwoman, the Atom, and many more. As the show resumed its eighth season earlier this week, the midseason opener served as an adventure for Bart and Nora West-Allen, a.k.a. Impulse and XS, respectively.

While Cosnett was originally set to appear for just the «flashback» episode, the Arrowverse drama has more plans for the Australian actor.

Even though The CW is keeping details under wraps, Cosnett will reportedly be «embodying» other characters.
