In the second-half of Supergirl's inaugral season, while trying to erase Colonel Jim Harper's memories, Martain Manhunter learned that Jeremiah Danvers (played by Dean Cain) -- who appeared to die a dozen years ago protecting J'onn J'onzz from the real-Hank Henshaw -- is alive and being kept at Project Cadmus. J'onn quickly revealed the shocking news to Jeremiah's biological and foster daughters, Alex and Kara, and he and Alex went in search of him, but they didn't find him by season's end.
Now in Season 2, the search continues! Although, they may not like what they find. In the previous episode, the Cadmus doctor played by Brenda Strong suggested that Jeremiah has been transformed, much in the same way John Corben became Metallo.
"We want to keep the mystery of who and what Jeremiah is alive," Executive Producer Andrew Kreisberg told EW. "He's been under Cadmus' control for the last 12 years. The Jeremiah that we see might not be exactly what people expect."
An attack is made on the President (guest star Lynda Carter) as hot-button, alien vs. human rights issues heat up in National City. Supergirl (Melissa Benoist) and the DEO are assigned to protect the President and bring in the responsible party. Alex (Chyler Leigh) teams up with Detective Maggie Sawyer (Floriana Lima) to investigate the case while Kara searches for a recently escaped Mon-El (Chris Wood), who she fears may be the alien behind the assault.
