Why Lex Luthor Hasn't Revealed Supergirl's Secret Identity, According To One Star

Few things are as essential to the superheroes of the Arrow-verse -- with the exception of Arrow itself nowadays -- as secret identities that allow them to fight the good fight without bringing that fight home to their loved ones. Supergirl's Kara Danvers has always hidden in plain sight, choosing not to wear a mask as Supergirl and simply going for a pair of glasses when not wearing the cape and boots. Kara's also gone to some extreme lengths to protect her secret identity, and that could spell trouble thanks to some Season 4 baddies.

If Kara was open about her double life as Supergirl, then she would be in a lot of trouble thanks to Red Daughter turning Supergirl into a public enemy. She even concealed the truth from some closest to her, including best friend Lena Luthor. Kara has kept the deception going long enough for Lena that it could get very ugly if and when Lena finds out the truth from somebody else.

Well, as it turns out, one of the people who does know Supergirl's secret identity could out the Girl of Steel to Lena in the not-too-distant future. The May 5 episode of Supergirl, called "Will The Real Miss Tessmacher Please Stand Up?," will see Eve set a trap for Kara and Lena that could reveal Kara as Supergirl.

Andrea Brooks, who plays the treacherous Miss Teschmacher, spoke with CinemaBlend about what's to come, and she had this to say when asked why Lex and Eve hadn't already exposed Kara as Supergirl:

I think that it could be revealed. I don't think it's on their priority list at this point. They're very concerned with their efforts to take over the world, global domination, universal domination. I don't think it ever kind of occurred to them that, hey, there's another character here that doesn't know everything that's going on. I don't think it's been their priority, but I think that there might be some ability to reveal this in a way that might be hurtful, and that might be the one reason why they would do it. But I think up until this point, they've been preoccupied with other things.

Kara Danvers as Supergirl may be the priority of viewers who have been watching the Girl of Steel for almost four full seasons so far, but as Andrea Brooks says, that's not the case for Lex Luthor and Eve Teschmacher. While Kara is on their radar, she just hasn't been as high on the list of priorities as global domination. What's one superhero compared to the attempt to take over the world, and perhaps even more?

If anything, Lex and Eve's actions have been more targeted at Lena, which is understandable. Thanks to her significant resources, genius, and soft spot for her brother, Lena was unintentionally key to Lex's plan to regain his freedom, and how could Lena have guessed that Eve had really been in Lex's pocket all along? The reveal that Eve had been Lex's double agent all along was a doozy for Lena and Supergirl fans for sure.

As much as Lena is a formidable foe, Eve isn't shrinking back from her former friend and boss in a sneak peek image from the next episode, even as Lena brandishes a weapon at her. Take a look!

Eve looks awfully confident for a woman being threatened with a blunt object by a member of the Luthor family, and Katie McGrath has really perfected a glare as Lena that makes it clear she's not to be messed with. Although Lena's face isn't visible in the image, it's probably safe to guess that she's not throwing her warmest smile in Eve's direction.

Of course, Eve does have reason to be confident in scenes with just Lena, and not just because she has leverage on Kara. Eve got to know Lena quite well while they worked together as Team Science. When I asked Andrea Brooks if Eve's confidence facing off against Lena could backfire on her, she said this:

I think it absolutely could come back to bite her. But her dealings with Lena are interesting, because this was such a deception and it was such a massive betrayal, and betrayal of course being Lena's kryptonite. Let's just say that Team Science has a lot to sort through in the next few episodes, and luckily you're going to see that play out... But luckily at this point, Eve does know Lena thinks and how she operates, so she does have that to her advantage. But we will have to see!

Honestly, Eve spilling the beans about Kara as Supergirl could be the perfect way to throw both Kara and Lena off their game for a while. The deception has begun to wear on the Girl of Steel more and more, as helping Lena as Supergirl meant that she had to neglect her friend as Kara. She's also in too deep for the reveal to not cause some damage. Years of deliberately lying -- even with the best of intentions -- won't work in her favor.

Lena is already struggling to deal with Eve's betrayal; wouldn't she see Kara's years of deception another kind of betrayal? Lena has enough on her plate with James' struggles and his family, the Lex twist, and Eve as a longtime double agent. If Eve reveals that another one of Lena's friends isn't what she seemed, nothing good could come of it. According to Andrea Brooks, though, there is still some hope for Eve to return to the side of good:

Anything is possible with this character. I always refer to Eve as an onion. She's multilayered, you never really know what you're going to get with her. So absolutely anything is possible with her. And I will say that despite everything, Eve does have a big heart. Under all of this, she has a heart. So there is hope, but you'll have to wait and see what happens.

The big question is, then, of who Eve's heart ultimately belongs to. Is she loyal to Lex to the core? Or did all that time working with Lena (and Kara) give her a soft spot that won't let her do anything too dastardly to them? Is there a line that she won't cross? Hopefully Supergirl will continue peeling back the layers of the "onion" of Eve's character.
