Is Supergirl about to shed her secret identity for good?!
ET has your exclusive sneak peek at the first footage from the CW drama's highly anticipated third season, and it seems like Kara Danvers (Melissa Benoist) is tired of hiding her true Kryptonian identity.
"I am not a human -- I tried to be, but I'm not," Supergirl shares in a dramatic voiceover. "Kara Danvers was a mistake."
The two-minute preview, which first debuted at Supergirl's Comic-Con panel on Saturday, features an unusually solemn Kara wresting with the fact that she had to banish Mon-El (Chris Wood) from Earth for his own protection.
"The decision I made, he couldn't have made that sacrifice," she said while images of Karamel's happier times
flashed on screen. "But me, I couldn’t have lived with myself if I hadn't. I will always make the decision I made."
The sneak peek trailer also featured a sweet Maggie and Alex smooch, the first look at Smallville'sErica Durance in the recently recast role of Alura Zor-El, and the debut of new series regular Odette Annable as season three's big villain Reign.
But there are even more new faces headed to Supergirl in season three!
It was announced on Saturday that Heroes and Agents of S.H.I.E.L.D. alum Adrian Pasdar is joining the show as Morgan Edge, a charming but ruthless real estate developer who has big plans for National City that immediately put him at odds with both Supergirl and Lena Luthor (Katie McGrath).
And while Reign has already been announced as one of this season's villains, fans can watch out for another female baddie in Jane the Virgin star Yael Grobglas, who will play Psi, a psychic villain who uses people's own minds against them.
But there's some good to be had too! DC Comics veteran Carl Lumbly will embody J'onn J'onnz's father, M'yrnn J'onnz, a peaceful religious leader on Mars who "pushes his son in unexpected ways." Lumbly will know exactly what buttons to press, having voiced the Martian Manhunter himself on the animated Justice League series!
And Supergirl will be getting yet another fangirl in Emma Tremblay's Ruby, a intelligent kid from National City, whose fascination with the Girl of Steel may land her in some trouble!
