Now that Myriad has been unleashed, Supergirl’s got a new mystery to unravel.

After Hank Henshaw was publicly unmasked as the Martian Manhunter (David Harewood), the former head of the DEO was sentenced to imprisonment at Project Cadmus, which was revealed to be a genetic engineering facility that experiments on aliens in order to weaponize their abilities for military purposes.

In the comics, Project Cadmus serves a somewhat similar function, though it’s best-known for its work in cloning, particularly with the creation of Superboy. Alas, the Supergirl bosses are staying relatively mum on whether the Boy of Steel will factor into the show’s future. “We can’t speak to that,” executive producer Andrew Kreisberg says. “You’re not going to see Cadmus this season. It’ll be something that gets saved for season 2.”

“We did run out of runway a little bit, so it’s going to remain more of a evil specter-y thing that’s out there,” Kreisberg continues. “It’s definitely something that we’re going to pursue. Cadmus has such a rich history in the comics and the animated shows. There’s so much there to mine. It’ll definitely be part of season 2.” (The CBS super series has not yet been renewed.)

While Hank and Alex (Chyler Leigh) didn’t end up as guinea pigs at the facility, they’re now on the hunt for it after discovering that Kara and Alex’s father, Jeremiah (Dean Cain), is actually still alive and trapped within the depths of Cadmus — though that may get derailed after Monday’s episode.

“[Alex] is on a mission, but Myriad taking over the entirety of National City is going to put into question which mission she should be pursuing,” Kreisberg says, teasing that we’ll see Alex and Hank on the run in a “comical way” in the April 11 episode. “Obviously she knows her father is alive and he’s out there, but the entirety of National City has been taken over, and there’s going to be some discussions with Hank in the subsequent episodes about which danger is more immediate and pressing.”

Supergirl airs Mondays at 8 p.m. ET on CBS.
