A new episode of Supergirl — the midseason finale! — airs tonight (December 4) at 8PM ET/PT on The CW, and to get people excited, the network has released an “Inside” video as well as a preview clip to promote it.
The episode is called “Reign” and the “Inside” video features Executive Producers Robert Rovner & Jessica Queller previewing what’s to come, complete with a bunch of clips. Burning a symbol all over the place is giving us Smallville flashbacks!
And speaking of Smallville flashbacks, Erica Durance is featured in the actual full clip, which features Kara discussing what is going on with her mother.
You can see both of the clips below; official preview photos from “Reign” can be found here.
