Flash Cast Member To Appear In The Superman & Lois Finale

The Flash’s Tom Cavanagh is not finished appearing in the Arrowverse (or Arrowverse-adjacent) shows, as he revealed this weekend at the FAN EXPO Philadelphia event on May 4 that he will be playing a role in the Superman & Lois series finale.

In the panel, Cavanagh explained how he preferred directing premieres or finales and had long grown a trust with showrunner Todd Helbing that he could always deliver, dating back to The Flash’s 100th episode which he directed. Since the Superman & Lois Season 4 finale is being directed by Gregory Smith, Cavanagh wasn’t able to do the finale this year, but instead, Helbing suggested that he appears in front of the camera.

“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?’ And so that’s coming up, for those of you that watch ‘Superman & Lois’ — something that I’m happy to have done,” Cavanagh explained at the panel.

The question now, of course, is who will Tom Cavanagh be playing? Harrison Wells or a variation of him? Eobard Thawne? Or, could it be someone entirely new… after all, Superman & Lois is not set in the same part of the multiverse. Or, he said “a role” – could it be something behind the scenes, and that to assume it’s an acting role could be a jump to conclusions. Either way, chances are good we won’t find out for sure until Superman & Lois Season 4 starts airing this Fall on The CW. For now, though, it might be fun to speculate.
