The gun control debate will return in the fourth season of Supergirl.

During season 3 of Supergirl, an episode called “Not Kansas” addressed the issue of gun control. The episode had Supergirl’s DEO allies attempt to stop a mass shooting, and confront a gun manufacturer about the morality of his chosen line of work. After much soul searching, J’onn announced that the DEO will be phasing out lethal weapons. This upsets some members of the organization.

The episode aired four months after the Parkland school shooting while the United States was still in a heavy debate on gun control. The episode was very controversial. Some fans took to Twitter and accused the show of being “too liberal”, while others praised it for daring to be topical and addressing the issue.

When season 3 concluded, J’onn left the DEO and put Supergirl’s foster sister Alex Danvers in charge. Some fans wondered if Alex would continue J’onn’s policy of phasing out guns, or if the show would ignore it.

On July 21, the cast of Supergirl participated in a media session during San Diego Comic-Con 2018. I had the chance to ask Alex Danvers actress Chyler Leigh about the weapon issue.

“Last season there was the plot point of the DEO phasing out lethal weapons. Are they going to follow up on that and continue on with that this year”, I inquired.

“That is a good question”, Chyler said. “We haven’t really gotten to at least that part of it from the DEO perspective yet. It’s still incorporated in the world outside of the DEO. I mean, you do see that. That’s life. That’s reality. That’s where we are right now and it’s more and more prominent”, she continued.

She made it clear that although it hasn’t been addressed yet, the DEO’s gun policy won’t be forgotten and she expects it to be revisited.

“We don’t just throw things in there just to have a one-off and do that and sometimes it can look that way until we are able to figure out how to bring it full circle. So a lot of the stories that were set up last season we’ll find opening up a lot more this coming season. And I do believe that’ll be a part of it and I think figuring that out and what that looks like when you’re… you know fighting against a ten foot alien that’s running out you and, you’re ‘like oh my net’ you know. So I don’t know. It’ll be interesting to see how they do that”, Chyler said.

What do you think? Should the DEO continue their lethal weapons ban? Does gun control belong on a show like Supergirl? How should the show address things going forward? Supergirl season 4 premieres Sunday, Oct. 14.
