‘Supergirl’ Season 2 Spoilers: Is Lena Luthor Hiding Something From Kara?

While some “Supergirl” fans suspect that Lena Luthor (Katie McGrath) has a scheme of her own that viewers are totally unaware of thus far, McGrath thinks that her enigmatic character has never been dishonest to Kara (Melissa Benoist).

“I think Lena is a very genuine person,” McGrath told TVLine. “What you see is what you get with her. She is honestly trying to do the best she can, and she is honestly a good person. [But] that’s not to say that other people don’t use her for ills. Because she’s the head of this company, she has all of these other relationships that people can manipulate — like her mother [Lillian (Brenda Strong)].”

“You think she’s going to ‘be a Luthor’ about something, but then she turns around and completely surprises you,” McGrath added of her character. “[That I] guess is what makes her an interesting character to watch — and definitely an interesting character to play.”

Although McGrath thinks that Lena is one of the good guys, the Irish actress said that there’s also a possibility that her character will be revealed as straight-up villain in Season 2 finale. “You know, she might!” McGrath told the website when asked if Lena isn’t going to introduce herself as a baddie at the end of the show’s sophomore run. “I haven’t read the end of the [season], so anything is possible.”

Regardless of what the future holds for Lena, McGrath said that her character and Kara are “bezzie mates” at this point.

Interestingly, Benoist finds Lena and Kara’s friendship the same way McGrath sees it. “I think they have a really special bond,” Benoist told Entertainment Weekly of Lena and Kara’s relationship. “The allure of the Luthor-Super relationship is so fascinating in the comics. I love where they’re taking it now. She has no caution to being friends with Lena. She just sees a good heart right now.”

McGrath was recently promoted to series regular for Season 3, so viewers will see more of Lena and Kara’s relationship moving forward.

“Supergirl” returns from its month-long hiatus with Season 2, episode 18 on Monday, April 24 at 8 p.m. EDT on The CW.
