Love or hate the Arrowverse, there's no denying that Tom Cavanagh's performance as the Reverse-Flash was hard to find fault with. As the years passed, The Flash diluted the character by having the actor play multiple versions of "Harrison Wells." However, in the suit, Cavanagh proved himself a truly formidable villain.
His story ended in the Scarlet Speedster's series, but we can look forward to at least one final appearance from the actor in the DC Universe.
Superman & Lois will conclude with its fourth and final season later this year, and unlike Legends of Tomorrow and Batwoman, the show's creative team have received enough notice to craft what we hope will be a satisfying ending.
The question now is, will that ending include an appearance from Eobard Thawne?
Appearing at FAN EXPO Philadelphia this past weekend, Cavanagh reflected on his work as a director behind the camera in the Arrowverse and explained why he always preferred helming premieres and finales. Unfortunately, he wasn't able to take charge of Superman & Lois' last episode (that honour goes to Gregory Smith), but showrunner Todd Helbing did have another offer.
"The finale for 'Superman & Lois' was taken up already, and so I said, 'Well, I’m happy to not do it,' which is when Todd was like 'Well, would you play a role?'" the actor recalled (via KryptonSite.com). "And so that’s coming up, for those of you that watch 'Superman & Lois' - something that I’m happy to have done."
While we'd bet on Cavanagh making a cameo appearance as a Dr. Harrison Wells doppelganger (remember, Superman & Lois takes place in its own, separate reality), it would be pretty wild for Reverse-Flash to show up and leave the door open to this world being revisited down the line.
When The Flash ended, Cavanagh shared his hopes for a Reverse-Flash spin-off. "I pitched Greg [Berlanti]...this idea that was like, 'Look at him as one of those Dragons of Yore that are impenetrable but for one weakness that is a scale and that is the vulnerability. What if Reverse-Flash fell for some paramore on Earth and that created the obstacle for him getting back, because much against his will, he’d fallen in love.'"
"That’s a human story. You can’t really tell that complicated of a Reverse-Flash story on a television show called The Flash, because you have to serve The Flash," he continued. "As a cast member, I’ve always been more than willing and ready to do that, but now that The Flash is done, there’s always room to explore that story. So, you never know."
Superman & Lois season 4 is expected to return to The CW this Fall.
