Supergirl Season 2 Episode 12: Luthors Photos Released

Following last Monday's Martain-centric episode, which concluded with Miss Martian heading back to Mars to find other like-minded White Martains, Supergirl will bring back Metallo (Frederick Schmidt) and the Luthors: Lena (Katie McGrath) and Lillian (Brenda Strong). Kara and Lena's friendship will be tested when it looks like the CEO of Luthor Corp is responsible for Lillian and Metallo escaping from their prisons.

Check out preview images in our gallery below.

LENA IS ARRESTED – After Metallo (guest star Frederick Schmidt) breaks out of prison and frees Lillian Luthor (guest star Brenda Strong), the police blame Lena (guest star Katie McGrath) for his escape and arrest her. Despite overwhelming evidence, Kara (Melissa Benoist) refuses to believe her friend is guilty and fights to clear Lena's name. Flashbacks reveal how Lena came to be a Luthor.

Meanwhile, Alex (Chyler Leigh) and Maggie (Floriana Lima) celebrate their first Valentine's Day together.

Tawnia McKiernan directed the episode written by Robert Rovner and Cindy Lichtman.
