After tonight’s airing of “Supergirl Lives” The CW presented a trailer for the January 30 episode of the series.

While we don’t have any official photos for it yet — hopefully we’ll have some of those in the next day or two — we know the episode is called “We Can Be Heroes” and features the return of Brit Morgan as Livewire. Here’s how The CW describes it:

LIVEWIRE IS SET LOOSE UPON NATIONAL CITY — After Livewire (guest star Brit Morgan) seemingly breaks out of prison, Supergirl (Melissa Benoist) is intent on recapturing her. After training Mon-El (Chris Wood), Supergirl takes him with her when she sees Livewire attack the NCPD but things go awry when Mon-El puts Supergirl before the citizens of National City. Meanwhile, James (Mehcad Brooks) decides to come clean with Kara and M’Gann (guest star Sharon Leal) has a psychic attack and collapses into a coma. Rebecca Johnson directed the episode written by Caitlin Parrish & Katie Rose Rogers (#210). Original airdate 1/30/2017.
