SPOILER WARNING: Season 2 of Supergirl discussed below!

Hot-on-the-heels of the awesome news that Saturn Girl will be played by Amy Jackson on Supergirl this season, The CW has released a new extended trailer, as well as a batch of pics from the Season 3 premiere, “Girl of Steel.”

When the show returns Oct. 9 on The CW, Kara (Melissa Benoist) will be diving deeper than ever into her role of Supergirl when a new threat arises (IMDb lists Yael Grobglas as Psi and Adrian Pasdar as Morgan Edge for the episode). And she'll also try to deal with the loss of Mon-El (Chris Wood) at the end of the dramatic Season 2 finale.

There’s also the upcoming nuptials between Alex (Chyler Leigh) and Maggie Floriana Lima) to look forward to (though we're told Alex will confess a secret to Maggie). Meanwhile, Erica Durance makes her debut as Alura Zor-El, replacing Laura Benanti in the role of Kara’s mom. While we’ve seen her in previous promos, the images give us another look at the Smallville actress in the Kryptonian role, as well as Odette Annable as the Season 3 big bad, Reign. Or should we say, Sam?

Have a look at the trailer above (narrated by Calista Flockhart's Cat Grant), then check out the gallery below for a closer look at “Girl of Steel.”
