Fans will see more of Katie McGrath in Season 3 of “Supergirl.”

According to Deadline, McGrath — who plays the enigmatic Lena Luthor on the show — has been promoted to series regular for the next season of the CW series.

McGrath made her debut appearance as Lena in Season 2, episode 1, in which she was introduced as the younger sister of Lex Luthor who came to National City to get out from under the shadow of her notorious sibling. The Irish actress has appeared in seven episodes of the show so far and is expected to return for more episodes before the superhero series ends its sophomore run in May.

Lena was last seen in Season 2, episode 12, in which she was blamed for the escape of Metallo (Frederick Schmidt) and her stepmother Lillian (Brenda Strong) from prison. But toward the end of the hour, Kara (Melissa Benoist) discovered that it was really Cyborg Superman (David Harewood) who helped Metallo and Lillian escaped jail. Lena was ultimately found not guilty, and she thanked Kara for standing up for her when the rest of the world thought that she’s evil just like her brother and her stepmom.

However, in her final shot in the episode, Lena seemed like she has something up her sleeve. Is she hiding something and playing a long game with Kara?

“That’s Lena’s journey for the series,” executive producer Andrew Kreisberg told Entertainment Weekly in February. “Are we who others think we are? Are we who we want to be? She’s not adopted, she’s actually truly a Luthor by blood, and is it nature vs. nurture? The audience’s perception of a character named Luthor mirrors the characters’ perception. ‘If your name is Luthor, you must be bad. That name is synonymous with evil.’”

It’s unclear whether Lena will appear in next week’s Season 2, episode 17 of “Supergirl,” but behind-the-scenes photos from the set confirmed that she will be in Season 2, episode 18, where she will be reunited with her former boyfriend Jack Spheer, played by “iZombie” actor Rahul Kohli.
