With Supergirl’s third season having now come to a close over in the US, it’s been revealed that Chris Wood won’t be returning as a series regular for the show’s already-confirmed fourth season.

In the Melissa Benoist-starrer, the charismatic Wood plays Mon-El. As has been revealed to TV Line, though, the plan was always to have Mon-El’s story play out over a two-season arc.

We guess we should give some sort of spoiler warning here, so be warned that we’re going to touch on the finale of Season 3 shortly.

Still with us? Good! While we’ve yet to actually see said season finale here in the UK, the episode will see Mon-El sent forward in time once again.

Speaking to TVLine, executive producer Robert Royner explained, “The plan for Chris was always to have him on the show for two years. We’ve loved telling Mon-El’s story, as well as the story we’ve told for him and Kara. We hope the fans felt that it was a satisfying conclusion.”

Fellow executive producer Jessica Queller added, “They both have destinies in different times as heroes. What they did was the sort of Casablanca decision of putting what’s most important to them – which is saving the world – first. It’s a little bittersweet that one destiny is to be a hero in this time and one’s destiny is to run the Legion in another time, but I think they grew a lot from knowing one another.”

While Mon-El won’t be back for the fourth season, a return isn’t completely off the table given how the Arrowverse has made a habit of bringing characters back over the years. And given how Mon-El is a part of the Legion, time-travel is a tool instantly at his disposal.

Supergirl airs on Sky1 here in the UK.
