This week’s episode of Supergirl focused heavily on our resident Martians, M’gann M’orzz (Sharon Leal) and J’onn J’onzz (David Harewood). Next week’s episode is going to focus on the very human (and very mischievous) mother/daughter pair of Lillian (Brenda Strong) and Lena Luthor (Katie McGrath). ‘Luthors’ is going to find Lena framed for aiding in the escape of her mother and Metallo (Frederick Schmidt) from prison. Will Kara (Melissa Benoist) be able to clear her friend’s name…or is Lena even completely innocent to begin with?

The photo gallery shows both Lillian and Lena behind bars, Metallo’s return, and Alex (Chyler Leigh) patching up James (Mehcad Brooks) in the DEO. Wonder what trouble Guardian got himself into this time…

The trailer for the episode has James guilt tripping Kara for not believing in him, Lillian convincing her daughter to join her in her fight against aliens, and…could that be Lex Luthor’s warsuit?!?!?
