'Supergirl': "Call To Action" Synopsis Released

The CW has released the official synopsis for "Call to Action," this year's Thanksgiving episode of Supergirl.

The episode apparently takes place after Kara (presumably in her civilian identity, though it's hard to tell) has a televised debate with Agent Liberty's civilian identity about anti-alien discrimination. Meanwhile, James and Lena are trying to figure out how to handle the Children of Liberty.

This is an interesting inversion, as it has Supergirl taking on a decidedly civilian role while James and Lena deal with supervillains, but it likely is just a one-off to make some kind of point for the holiday episode and not a broader status quo for the show.

No word yet on whether Helen Slater, who plays Kara and Alex's mother, will appear in the episode, as she has in previous Thanksgiving episodes to celebrate with her family. Both she and Dean Cain, who plays her estranged husband, have not yet appeared in this season of the series.
