Kara isn't the only Danvers sister to hold the mantle of Supergirl in an upcoming episode from Season 5.
The CW has released a promo for the season's 16th episode, titled "Alex in Wonderland," which sees Alex use Obsidian technology to relax in a virtual reality world. Here, she becomes her own version of Supergirl before her friends realize she's trapped within her new persona.
As the team scrambles to rescue Alex, Obsidian Tech CEO Andrea Rojas notes that only a secure shock can bring her back to the real world, leaving the longtime character desperately clinging to her virtual delusions.
In the face of the growing coronavirus (COVID-19) pandemic, production on the remaining episodes of Season 5 has been suspended as a precautionary measure, following suit from other CW productions in the Vancouver area. There have been no updates on how this will impact the remainder of the season, which is presently slated to air its season finale in May.
Airing Sundays at 9 p.m. ET/PT on The CW, Supergirl stars Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter and Chyler Leigh as Alex Danvers.
