freed by Hank Henshaw and Corben/Metallo. All three go to a remote facility built by her son to unleash a powerful nuclear weapon to wipe out alien beings in National City; the plan is thwarted by Supergirl and Corben dies in facility while Lillian and Henshaw escape. In the episode "Homecoming", it is revealed that Jeremiah has joined Cadmus as well. After his rescue from Cadmus soldiers, Supergirl and her family celebrate his return, except for Mon-El who is suspicious of him. At the same time Cadmus apparently made a fusion bomb using energy from Supergirl's heat vision in order to frame aliens for dropping it on National City, but it is discovered to be a ruse.

After rescuing them, Lillian and Hank betray Kara and Mon-El to leave them behind while beaming only Lena and themselves to the Fortress. However, Kara expected her betrayal and her friend Winn Schott Jr. put a bug device on Hank prior to the rescue operation. She turns on the device to
