There is a new preview for tonight's Supergirl, where we see Alex Danvers (Chyler Leigh) beating on a bald prisoner as she tries to find out where Cadmus is. They don't tell us the prisoner's name, but since she is asking about Cadmus and the Luthors, some folks are guessing that he's Lex. I doubt that. But we do get the standard trope of the hero getting out of control and beating a suspect before someone else comes in and pulls them off before they can get the answer. This is usually followed by the obligatory, 'you're too close to this' speech and threat of suspension. Will J'onn J'onzz (David Harewood) give that speech tonight? We'll have to wait and see.
Supergirl airs Mondays at 8 PM on the CW.
