Supergirl Photos: Dichen Lachman as Roulette, More Alex/Maggie Bonding

Genre-TV vet Dichen Lachman takes the DC Comics villainess Roulette for a spin in photos from Monday’s episode of The CW’s Supergirl. Also, Alex manages to cross paths again with NCPD Detective Maggie Sawyer.

In the fourth episode of Season 2, “Survivors,” when Kara and Alex investigate the murder of an unregistered alien, the trail leads to a fight club run by Roulette, where aliens slug it out for the amusement of humans. While trying to stop the fighting, Supergirl and Martian Manhunter find themselves up against a surprising opponent.

Elsewhere, Hank is thrilled to have found another Martian and tries to get to know M’Gann (played by Sharon Leal) better. Also, Supergirl takes Mon-El under her wing and begins to train him.
