Cat Grant recently saw double on Supergirl when Kara Danvers enlisted Hank Henshaw to prove that she wasn’t her superhero alter ego. But when Kara faces off against a mirror image of herself in the show’s Feb. 1 episode, it won’t be actress Melissa Benoist taking on double duty. CBS has confirmed that Hope Lauren will play Bizarro Girl, a twisted version of Supergirl set on destroying the real Kara.

“Cat coins her Bizarro, which is very appropriate,” Supergirl EP Andrew Kreisberg tells EW. “As she says, I can name Supergirl, I can name her enemies. The biggest thing about it that was a surprise for us as we constructed the character and the arc was how sad Bizzaro is. In a way, we sort of think about her like Frankenstein[‘s monster]. She’s a monster, but she has a pure child’s heart. Ironically, in the episode, while everyone else is saying, ‘We have to figure out a way to destroy her,’ Kara is the only one saying, ‘No, no, no, we have to save her.’ That makes the episode so emblematic of what’s so special about Kara. She’s looking to save everybody, even if they’re the bad guy.”
