Introducing Kara Danvers and Cat Grant

On the TV show Supergirl, Kara Danvers and Cat Grant have a complex relationship. Cat Grant is the founder and CEO of CatCo Worldwide Media, a global media company where Kara works as Cat’s assistant in her secret identity (Cat Grant | Arrowverse Wiki | Fandom). This positions Cat as Kara’s boss, though their dynamic grows into more of a mentorship over time.

As Kara’s boss, Cat often treats her harshly and makes demanding requests. However, she also pushes Kara to reach her full potential and gives her opportunities to advance her career as a reporter at CatCo. Their day-to-day interactions in the workplace play a key role in the evolution of their unique bond.

Cat Directly Confronts Kara

In season 1 of Supergirl, there is a pivotal moment when Cat Grant directly confronts Kara Danvers about her secret identity. Having grown suspicious of the uncanny similarities between her meek assistant and the heroic Supergirl, Cat decides to directly call out Kara in her office.

“Kara, I know your little secret,” Cat says bluntly, catching Kara completely off guard. Kara nervously tries to deflect, adjusting her glasses and pretending not to know what Cat means. But Cat continues pushing, outright telling Kara that she knows she is Supergirl.

Despite being cornered, Kara denies Cat’s accusation and sticks to her secret identity story. She makes excuses about why she couldn’t possibly be Supergirl, saying things like she’s just a normal girl from Midvale. Kara refuses to jeopardize her privacy and safety by confirming anything, no matter how much evidence Cat presents.

This tense confrontation highlights the budding dynamic between Kara and Cat. It shows Cat’s perceptiveness and refusal to be fooled, contrasted by Kara’s commitment to keeping her heroic alter ego separate from her civilian life. Their back and forth over Kara’s biggest secret solidifies their complicated, almost maternal relationship.

Why Kara Keeps Her Identity Secret

Kara Danvers, known to the world as Supergirl, keeps her superhero identity a closely guarded secret for several important reasons. According to discussions on Reddit (, Kara originally kept her powers hidden because she was insecure and uncertain of her role on Earth. However, over time she realized the importance of protecting her secret identity both to keep her loved ones safe and to attempt living a normal life.

As explained on Quora (, Supergirl’s identity is closely guarded by the DEO to prevent her enemies from targeting her friends and family in order to get to her. Supergirl has experienced many threats due to her superhero status, so maintaining a secret identity provides a layer of protection. According to CBR (, Kara vowed to keep her powers hidden when she first arrived on Earth, though she would use them in secret to help people while outwardly living as Kara Danvers.

Keeping her Supergirl identity separate from Kara Danvers also allows her to experience life on Earth as normally as possible. As a refugee from Krypton, she strives to fit into human society. Her secret identity gives her that chance while still letting her use her powers for good.
