“Kara investigates a secretive new group whose leader, Thomas Coville (guest star Chad Lowe), has a mysterious connection to Supergirl.
Meanwhile, Samantha (Odette Annable) feels like she’s letting Ruby (guest star Emma Tremblay) down, and J’onn confesses an old secret.”
Following last night’s episode, The CW has released the first trailer for next week’s episode of Supergirl featuring the girl of steel as she battles one of her strangest foes yet – a deadly cult.
The DC villain’s big plans for National City instantly put him at odds with Supergirl (Melissa Benoist) and Lena Luthor (Katie McGrath); Carl Lumbly (Alias, Southland, The Cure for Wellness) plays classic DC character M’yrnn J’onzz, the father of J’onn J’onnz, the Martian Manhunter (David Harewood).
