Supergirl is about to get a visit from one of DC Comics' greatest villains of all time!
The CW released a first look photo of none other than Lex Luthor (Jon Cryer) Wednesday, and he's exactly where we expected him to be: prison. Whether he'll stay there or not is up for debate, but you can't deny that Lex looks pretty malevolent staring you down from inside his cell. It's enough to make even the Man of Steel shiver.
Lex will be making his debut in Episode 15, entitled "O Brother, Where Art Thou?", on Sunday, March 17. As expected, he will reach out to his sister, Lena (Katie McGrath), hoping to enlist her in his latest plan. Lex will stop at nothing to get Lena on his side, even if it means leveraging the life of one of her friends. On one hand, we're super nervous for Kara (Melissa Benoist), since she seems like the obvious choice for Lex to use as leverage, but on the other hand... Oh boy, does Lex not know what he's getting himself into by trying to put the pressure on Supergirl.
You have to wonder, though: How much longer can Kara keep her secret from Lena? This situation is exactly the kind of thing that would blow her secret identity out of the water!
Supergirl airs Sundays at 8/7c on The CW.
