The Girl of Steel is back! Filming for "Supergirl" Season 2 is well underway, and David Harewood -- who plays the Martian Manhunter himself -- celebrated the occasion with a new super-selfie.

In the photo, Harwood stands between Melissa Benoist (Supergirl) and Chyler Leigh (Alex Danvers). Behind them, fans will spy what appears to be a new set; since Harewood helpfully tagged the photo #DEO, it looks like the Department Of Extranormal Operations is getting something of an upgrade. This version of the DEO looks a bit more streamlined than its cave-like counterpart, albeit just as cold and concrete.

Since "Supergirl" is jumping networks from CBS to The CW this fall, it makes sense that the show would undergo a few changes. It seems, in this photo, that the DEO's location is just one of these.

Starring Melissa Benoist, David Harewood, Chyler Leigh and more, the second season of "Supergirl" is scheduled to premiere on Monday, October 10 at 8 pm EST on The CW, switching networks after a first season on CBS.
