The CW has released an official trailer for the Supergirl episode “Reign.” Hopefully this means we’ll have some official photos soon. Here’s how the network describes it:
REIGN CHALLENGES SUPERGIRL – Supergirl (Melissa Benoist) investigates a mysterious symbol popping up all over National City, tracing its origins back to an ancient prophecy and the mark of the World Killer, Reign (Odetee Annable). Meanwhile, the tension between Lena (Katie McGrath) and Morgan Edge (guest star Adrian Pasdar) continues to build, causing James to step in and offer up some protection, and possibly igniting a spark in the process. Glen Winter directed the episode written by Paula Yoo & Caitlin Parrish (#309). Original airdate 12/4/17.
The trailer for the episode, which airs December 4, can be found below.
