Katie McGrath as Lena Luthor

Some “Supergirl” fans are convinced that Lena Luthor (Katie McGrath) is hiding something from Kara (Melissa Benoist), and that suspicion leads them to think that Kara should neither trust Lena nor make friends with her. But in an interview previewing the remaining episodes of Season 2, Benoist said that Kara has currently no reason to question Lena’s truthfulness.

“Not at this point, no,” Benoist told Entertainment Weekly when asked if Kara starts doubting Lena’s friendliness to her. “I think they have a really special bond. 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.”

And because Kara and Lena’s friendship has really gotten stronger since the latter was introduced to the series, Benoist said that “it would be devastating” if Kara ends up facing off against Lena in the future.

“Are we who others think we are? Or are we who we want to be? That’s Lena’s journey for the series,” executive producer Andrew Kreisberg told Entertainment Weekly in a separate interview in February. “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.’”

Kreisberg added that Lena’s storyline on the series will further highlight one main difference between Supergirl and her cousin, Superman (Tyler Hoechlin).

“Watching every character have their moment with [Lena] where they doubt and do they believe, it’s so interesting,” Kreisberg said. “Even Clark, when we had Superman on, didn’t trust her because of that name. It’s the difference between Kara and Clark, in our interpretation of these characters, is that Superman is a little jaded after doing this for so long, and Kara is still wide-eyed and fresh-faced and still believes in the goodness in people. Whether or not Kara and Supergirl’s belief in Lena is going to be enough to overcome the corrupting influence of Lillian (Brenda Strong) is the plot of the series.”

It was revealed last month that McGrath was promoted to series regular for Season 3, so this means that the show has more time to develop Kara and Lena’s relationship moving forward.

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