Melissa Benoist as Kara

“Supergirl” star Melissa Benoist said that Kara will continue to struggle with whether to finally tell Lena the truth about her alter ego now that she’s her boss.

“I think Kara (Benoist) probably battles that more often than we see because Lena’s (Katie McGrath) her best friend and she’s told every other confidant in her life,” Benoist recently told Entertainment Weekly. “She probably struggles with that on a daily basis. She probably knows deep down that it wouldn’t be the greatest thing to reveal to someone of that lineage.”

In Season 3, episode 2, Lena stayed at CatCo all day, and that gave Kara a hard time keeping up appearances as both Supergirl and Kara. It’s unclear when Lena will exactly find out about Kara and Supergirl being the same person, but if McGrath were to decide, the Irish actress said that she would like her character to remain in the dark a little bit longer.

“Part of the fun is the fact that she’s one of the only people who doesn’t know, and that gives their relationship something different than she has with anybody else,” McGrath told Entertainment Weekly last May. “With Lena, Kara can just be Kara; she can be Kara Danvers, not the superhero. She doesn’t have this weight and this responsibility on her. All she has to do when she’s with Lena is be a good friend. So I hope you, in a way, never see it, because what you have between the two is a very equal relationship. Lena doesn’t have to be this powerful corporate leader, she can just be a flawed human being, and so can Kara. The longer that you don’t ever see that, to me, the better.”

When asked how she thinks Lena would react if she learned that Kara is in fact the Girl of Steel, McGrath said that she thinks her character would feel a little betrayed but would ultimately understand why Kara kept her superhero identity a secret from her.

“She’s very accepting to aliens and people that are different, so why would she be any different with Kara?” McGrath said of Lena. “Absolutely she’d feel, in a way, betrayed and hurt that her friend hadn’t trusted her, but at the same time, I think she’s a very levelheaded person, so she understands that it would be difficult for Kara to ultimately trust a Luthor with that secret. ... I’d like to think she’d be very accepting of her best friend and the fact that her best friend is different.”

“Supergirl” Season 3 airs Mondays at 8 p.m. EDT on The CW.
