Supergirl Just Dropped Two Big Cadmus Twists On Viewers

Warning: spoilers ahead for the latest episode of Supergirl.

Supergirl is the sunniest superhero series on The CW, but the latest episode took Kara to some very dark places as she finally got an up close and personal look at Project Cadmus. Thanks to the evil deeds of Cadmus head honcho Lillian Luthor, Kara Danvers first faced off against a scheming Cyborg Superman/the real Hank Henshaw, and then reunited with her foster dad Jeremiah. The questions now are of just what the ginormous Cadmus twists mean for the rest of Supergirl Season 2.

Kara was in a rough situation in Cadmus after Lillian Luthor forced Supergirl to drain her own superpowers by overusing her heat vision. Lillian used Kara's vulnerability to extract a blood sample, then threw her back into a cell alongside an injured Mon-El. Luckily for the two aliens, none other than Jeremiah Danvers emerged from the shadows to free them. He pried the lead bullet out of Mon-El's leg, hugged Kara and offered some inspiring words, and then used a passkey and his clear familiarity with the building to guide them to safety.

Jeremiah refused to join Kara and Mon-El as they raced back to the D.E.O. in what was an act of major self-sacrifice...or part of a Project Cadmus ploy to let Kara think she had an ally on the inside. After all, Cadmus has had more than a decade to rewire Jeremiah, so to speak. It's entirely possible that he was acting on orders from Lillian Luthor to release Kara and Mon-El after she got her blood sample. Kara may have her guard dangerously low the next time she and Jeremiah meet.

The final scene of the episode revealed just why Lillian Luthor needed Kara's blood. My first thought was that the blood draw was the way that Supergirl would be creating its own Superboy-esque clone plot, but Cadmus' plans were much more dastardly. Cyborg Superman arrived at the Fortress of Solitude and used Kara's blood to access Kryptonian technology and memory files. The blood tricked the computer into believing that Kara was present and requesting information, and so Cyborg Superman's demand for details about the mysterious "Project Medusa" met with no objections.

Project Cadmus now has access to alien technology that could be instrumental in achieving their goals of ridding the Earth of visitors from outer space, and we can bet that the fallout with Project Medusa will be ugly. Only time will tell how ugly. Going by what we know of next week's episode, it looks like Project Medusa will involve a Cadmus virus designed to instantly kill any and all aliens in the area.

Given that the huge crossover between Supergirl, The Flash, Arrow, and Legends of Tomorrow is slated for next week, however, we may have to wait a bit to find out everything we want to know about Jeremiah Danvers, Cyborg Superman, and Project Cadmus. Tune in to The CW on Mondays at 8 p.m. to catch episodes of Supergirl.
